A Letter to Shareholders


Dear Shareholder

In its first four months, 2007 could already be termed an eventful year for
investors. For most financial markets, 2007 opened just as 2006 ended - on a
positive trajectory. Then, at the end of February and into March, global
equity markets registered their first significant decline since last summer.
The market jitters were triggered by a significant setback in the Chinese
market and were exacerbated by worries of a weakening economy, escalating
geopolitical concerns and rising delinquencies in the subprime mortgage
market. Still, underlying stock market fundamentals appeared quite sound,
supported by a generally favorable global economic backdrop, tame inflation,
slowing but still positive earnings growth, relatively low interest rates and
attractive valuations. These conditions prevailed later, and the Dow Jones
Industrial Average crossed the 13,000 mark for the first time in its history
in late April.

Not unlike the equity market, the bond market also experienced volatility as
observers attempted to interpret mixed economic signals. A bond market rally
(falling yields and rising prices) late last year reversed itself early in
2007 amid some transitory signs of economic strength. Overall, yields have
fluctuated month to month but ended April little changed from the beginning of
the year. However, compared to one year ago, yields on 30-year Treasury bonds
fell 36 basis points (.36%) and 10-year yields fell 44 basis points, while
prices correspondingly rose.

For its part, the Federal Reserve Board (the Fed) has left the target short-
term interest rate on hold at 5.25% since first pausing in its interest rate-
hiking campaign on August 8, 2006. The central bankers continue to express
concern about potential inflationary pressures, but also acknowledge signs of
economic weakness. Given this relatively "balanced" assessment, most observers
believe the Fed will keep interest rates on hold for now.

Against this backdrop, most major market indexes posted positive returns for
the annual and semi-annual reporting periods ended April 30, 2007:

If the first four months are any guide, 2007 could be a year of enhanced
market volatility. As you navigate the un-certainties, we encourage you to
review your investment goals with your financial professional and to make
portfolio changes, as needed. For more insight, we invite you to view "What's
Ahead in 2007: An Investment Perspective" and "Are You Prepared for
Volatility?" at www.blackrock.com/funds. We thank you for entrusting BlackRock
with your investment assets, and we look forward to continuing to serve you in
the months and years ahead.

BLACKROCK HEALTHCARE FUND, INC.                                  APRIL 30, 2007



Discussion With Your Fund's Portfolio Manager


We continued our long-term strategy of stressing more growth-oriented health
care subsectors as well as more defensive holdings in order to balance upside
potential and downside risk in the portfolio.


How did the Fund perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended April 30, 2007, BlackRock Healthcare Fund,
Inc.'s Institutional, Investor A, Investor B, Investor C and Class R
Shares had total returns of +10.62%, +10.43%, +9.41%, +9.47% and +9.98%,
respectively. (Fund results shown do not reflect sales charges and would be
lower if sales charges were included. Complete performance information can be
found on pages 6 and 7 of this report to shareholders.) Fund performance
lagged the broader stock market as represented by the Standard & Poor's (S&P)
500 Index, which posted a total return of +15.24% for the 12-month period. The
Russell 3000 Healthcare Index returned +16.03% for the same period.

As the Fund's fiscal year began in May 2006, the broad equity market was at an
all-time high and still on the upswing based on expectations that the Federal
Reserve Board (the Fed) would suspend its two-year string of interest rate
hikes. Interest-rate-sensitive stocks led the rally while the more defensive
health care sector (in that it is less sensitive to interest rate movements)
ranked at the bottom of all U.S. industries in terms of performance at this
time. Shortly thereafter, the market pulled back as super-heated commodity
prices, especially metals prices, sparked inflationary concerns. The markets
again began to anticipate a rise in interest rates.

As 2006 progressed, inflationary fears settled back and the anticipated
interest rate hikes did not materialize. Investor concern shifted from
inflation to slowing economic growth and the possibility that it could
eventually lead the United States into recession. Investor speculation of a
Fed interest rate cut arose and continued amid the slow-growth, mildly
inflationary economy that developed. In this environment, the equity market,
as measured by the Dow Jones Industrial Average, rose steadily (albeit with a
pullback in March 2007) to a series of new all-time highs. The health care
sector moved from the bottom of the industry performance rankings in calendar
year 2006 to a leading position in early 2007. Investors recognized the
reasonable valuations, sturdy dividends (especially from pharmaceutical
companies), modest exposure to the anticipated weaker economy and currency
benefits from a weak U.S. dollar, as well as robust earnings stemming from the
new Medicare prescription drug program. Political concerns about the apparent
strength of congressional Democrats, who have declared pharmaceutical price
cuts to be a top priority in their agenda, were deferred. It was generally
judged that damaging legislation, although still a very real prospect, was
unlikely until 2009 at the earliest (after the 2008 election), with
implementation possible by sometime in 2010 or 2011.

The Fund's performance generally mirrored that of the health care sector, with
strength emerging in the fourth quarter of 2006 and continuing through period-
end. The major reason for the Fund's underperformance in the earlier part of
the fiscal year was its subsector allocation within the health care universe.
We adapted a somewhat more concentrated - but still diversified - portfolio
position in late 2006, and relative performance for the remainder of the
fiscal period improved. Our focus on the pharmaceutical industry for its
defensive characteristics and biotechnology for its upside potential proved to
be highly effective, and the Fund matched the market performance of both
subsectors during the last eight months of the fiscal year. Another positive
influence on Fund performance in the first four months of 2007 was our reduced
weighting in the managed care (HMO) subsector that resulted from the portfolio
changes in late 2006. As a consequence, the Fund outperformed the Russell 3000
Healthcare Index and the S&P 500 Index in the first four months of calendar
year 2007.



BLACKROCK HEALTHCARE FUND, INC.                                  APRIL 30, 2007



What changes were made to the portfolio during the period?

During the 12-month period, the Fund's subsector weightings were only slightly
changed, but substantial changes to stock weightings took place due to market
price action. Abbott Laboratories, for example, rose by 37% to become the
Fund's largest position. This diversified pharmaceutical company appears
poised to become a leader in the drug-coated stent market, which should
supplement its well-accepted arthritis drug, Humira. We reduced our position
in Sanofi-Aventis as delays in U.S. approval of Acomplia, the company's
obesity-treatment drug, dampened our enthusiasm. In our pharmaceutical
holdings, we eliminated Wyeth and reduced our position in Novartis AG as we
diversified the portfolio. Important additions to the portfolio included Bayer
AG, a leading German drug and chemical company; Baxter International, Inc., a
diversified healthcare company; and Intuitive Surgical, Inc., the pioneer and
leading robotic surgery company.

In general, we continued our long-term strategy of stressing more growth-
oriented subsectors as well as more defensive holdings in order to balance
upside potential and downside risk. We have focused on biotechnology for its
upside potential based on new drug discoveries, and on pharmaceuticals for
their defensive strength due to reasonable valuations and substantial dividend
yields. Throughout the fiscal year, the number of holdings in the portfolio
decreased from 78 to 71 as we worked to increase the portfolio's liquidity by
shifting to large-capitalization positions.


How would you characterize the Fund's position at the close of the period?

On April 30, 2007, the Fund was more heavily weighted in large- and mid-cap
holdings, reflecting our deliberate effort to increase liquidity, given our
belief that the broader stock market advance had matured. U.S. holdings
accounted for 79.5% of the Fund's net assets at period-end, higher than a year
ago, as the earnings of larger domestic multinational companies were buoyed by
stronger non-U.S. currencies. The Fund's emphasis at fiscal year-end continued
to be on pharmaceuticals, medical devices and biotechnology companies.
Overall, we believe the Fund to be appropriately positioned in the climate
of economic slowdown and/or heightened inflation threat that existed at
period-end.

Performance Data


About Fund Performance


Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I
Shares were redesignated Investor A, Investor B, Investor C and Institutional
Shares, respectively. Class R Shares did not change their designation. As
previously communicated to shareholders, new sales charge schedules came into
effect at the same time for certain of these classes.

The Fund has multiple classes of shares:

* Institutional Shares are not subject to any sales charge. Institutional
Shares bear no ongoing distribution or service fees and are available only to
eligible investors.

* Investor A Shares incur a maximum initial sales charge (front-end load) of
5.25% and a service fee of 0.25% per year (but no distribution fee).

* Investor B Shares are subject to a maximum contingent deferred sales charge
of 4.50% declining to 0% after six years. In addition, Investor B Shares are
subject to a distribution fee of 0.75% per year and a service fee of 0.25% per
year. These shares automatically convert to Investor A Shares after
approximately eight years. (There is no initial sales charge for automatic
share conversions.) All returns for periods greater than eight years reflect
this conversion.

* Investor C Shares are subject to a distribution fee of 0.75% per year and a
service fee of 0.25% per year. In addition, Investor C Shares are subject to a
1% contingent deferred sales charge if redeemed within one year of purchase.

* Class R Shares do not incur a maximum initial sales charge (front-end load)
or deferred sales charge. These shares are subject to a distribution fee of
0.25% per year and a service fee of 0.25% per year. Class R Shares are
available only to certain retirement plans. Prior to inception, Class R Share
performance results are those of Institutional Shares (which have no
distribution or service fees) restated for Class R Share fees.

Performance information reflects past performance and does not guarantee
future results. Current performance may be lower or higher than the
performance data quoted. Refer to www.blackrock.com to obtain performance data
current to the most recent month-end. Performance results do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares. Figures shown in each of the following tables
assume reinvestment of all dividends and capital gain distributions, if any,
at net asset value on the ex-dividend date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be worth
more or less than their original cost. Dividends paid to each class of shares
will vary because of the different levels of service, distribution and
transfer agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

Disclosure of Expenses


Shareholders of this Fund may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and exchange
fees; and (b) operating expenses including advisory fees, distribution fees
including 12b-1 fees, and other Fund expenses. The following example (which is
based on a hypothetical investment of $1,000 invested on November 1, 2006 and
held through April 30, 2007) is intended to assist shareholders both in
calculating expenses based on an investment in the Fund and in comparing these
expenses with similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during
the period covered by this report, shareholders can divide their account value
by $1,000 and then multiply the result by the number in the first line under
the heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders'
ongoing costs only and do not reflect any transactional expenses, such as
sales charges, redemption fees or exchange fees. Therefore, the second table
is useful in comparing ongoing expenses only, and will not help shareholders
determine the relative total expenses of owning different funds. If these
transactional expenses were included, shareholder expenses would have been
higher.

  * For each class of the Fund, expenses are equal to the annualized expense ratio for the class
    (1.34% for Institutional, 1.58% for Investor A, 2.37% for Investor B, 2.37% for Investor C and
    1.94% for Class R), multiplied by the average account value over the period, multiplied by
    181/365 (to reflect the one-half year period shown).

 ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in
    the most recent fiscal half year divided by 365.

BLACKROCK HEALTHCARE FUND, INC.                                  APRIL 30, 2007



Notes to Financial Statements


1. Significant Accounting Policies:
On September 29, 2006, Merrill Lynch Healthcare Fund, Inc. was renamed
BlackRock Healthcare Fund, Inc. (the "Fund"). The Fund is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, open-end
management investment company. The Fund's financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may
require the use of management accruals and estimates. Actual results may
differ from these estimates. The Fund offers multiple classes of shares.
Effective October 2, 2006, Class I, Class A, Class B and Class C Shares were
redesignated Institutional, Investor A, Investor B and Investor C Shares,
respectively. Class R Shares did not change their designation. Institutional
Shares are sold without a sales charge and only to certain eligible investors.
Investor A Shares are sold with a front-end sales charge. Shares of Investor B
and Investor C may be subject to a contingent deferred sales charge. Class R
Shares are sold only to certain retirement plans. All classes of shares have
identical voting, dividend, liquidation and other rights and the same terms
and conditions, except that Investor A, Investor B, Investor C and Class R
Shares bear certain expenses related to the shareholder servicing of such
shares, and Investor B, Investor C and Class R Shares also bear certain
expenses related to the distribution of such shares. Each class has exclusive
voting rights with respect to matters relating to its shareholder servicing
and distribution expenditures (except that Investor B shareholders may vote on
material changes to the Investor A distribution plan). Income, expenses (other
than expenses attributable to a specific class) and realized and unrealized
gains and losses are allocated daily to each class based on its relative net
assets. The following is a summary of significant accounting policies followed
by the Fund.

(a) Valuation of investments--Equity securities held by the Fund that are
traded on stock exchanges or the NASDAQ Global Market are valued at the last
sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available
asked price for short positions. In cases where equity securities are traded
on more than one exchange, the securities are valued on the exchange
designated as the primary market by or under the authority of the Board of
Directors of the Fund. Long positions traded in the over-the-counter ("OTC")
markets, NASDAQ Capital Market or Bulletin Board are valued at the last
available bid price or yield equivalent obtained from one or more dealers or
pricing services approved by the Board of Directors of the Fund. Short
positions traded in the OTC markets are valued at the last available asked
price. Portfolio securities that are traded both in the OTC markets and on a
stock exchange are valued according to the broadest and most representative
market.

Options written or purchased are valued at the last sale price in the case of
exchange-traded options. Options traded in the OTC market are valued at the
last asked price (options written) or the last bid price (options purchased).
Swap agreements are valued based upon fair valuations received daily by the
Fund from a pricing service or counterparty. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges. Obligations with remaining maturities
of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC
(the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc.,
believes that this method no longer produces fair valuations. Valuation of
other short-term investment vehicles is generally based on the net asset value
of the underlying investment vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. The Fund
employs pricing services to provide certain securities prices for the Fund.
Securities and assets for which market quotations are not readily available
are valued at fair value as determined in good faith by or under the direction
of the Board of Directors of the Fund, including valuations furnished by the
pricing services retained by the Fund, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are
reviewed by the officers of the Fund under the general supervision of the
Fund's Board of Directors. Such valuations and procedures will be reviewed
periodically by the Board of Directors of the Fund.



BLACKROCK HEALTHCARE FUND, INC.                                  APRIL 30, 2007



Notes to Financial Statements (continued)


Generally, trading in foreign securities, as well as U.S. government
securities, money market instruments and certain fixed income securities, is
substantially completed each day at various times prior to the close of
business on the New York Stock Exchange ("NYSE"). The values of such
securities used in computing the net asset value of the Fund's shares are
determined as of the close of business on the NYSE. Foreign currency exchange
rates will generally be determined as of the close of business on the NYSE.
Occasionally, events affecting the values of such securities and such exchange
rates may occur between the times at which they are determined and the close
of business on the NYSE that may not be reflected in the computation of the
Fund's net asset value. If events (for example, a company announcement, market
volatility or a natural disaster) occur during such periods that are expected
to materially affect the value of such securities, those securities will be
valued at their fair value as determined in good faith by the Fund's Board of
Directors or by the Manager using a pricing service and/or procedures approved
by the Fund's Board of Directors.

(b) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized.
Assets and liabilities denominated in foreign currencies are valued at the
exchange rate at the end of the period. Foreign currency transactions are the
result of settling (realized) or valuing (unrealized) assets or liabilities
expressed in foreign currencies into U.S. dollars. Realized and unrealized
gains or losses from investments include the effects of foreign exchange rates
on investments. The Fund invests in foreign securities, which may involve a
number of risk factors and special considerations not present with investments
in securities of U.S. corporations.

(c) Derivative financial instruments--The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the
securities markets. Losses may arise due to changes in the value of the
contract due to an unfavorable change in the price of the underlying security,
or if the counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such financial futures contracts. Financial futures
contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract,
the Fund deposits, and maintains as collateral, such initial margin as
required by the exchange on which the transaction is effected. Pursuant to the
contract, the Fund agrees to receive from or pay to the broker an amount of
cash equal to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund as
unrealized gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.

* Foreign currency options and futures--The Fund may also purchase or sell
listed or OTC foreign currency options, foreign currency futures and related
options on foreign currency futures as a short or long hedge against possible
variations in foreign exchange rates. Such transactions may be effected with
respect to hedges on non-U.S. dollar denominated securities owned by the Fund,
sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

* Forward foreign exchange contracts--The Fund may enter into forward foreign
exchange contracts as a hedge against either specific transactions or
portfolio positions. The contract is marked-to-market daily and the change in
market value is recorded by the Fund as an unrealized gain or loss. When the
contract is closed, the Fund records a realized gain or loss equal to the
difference between the value at the time it was opened and the value at the
time it was closed.

* Options--The Fund may purchase and write call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked-to-market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or deducted from)
the basis of the security acquired or deducted from (or added to) the proceeds
of the security sold. When an option expires (or the Fund enters into a
closing transaction), the Fund realizes a gain or loss on the option to the
extent of the premiums received or paid (or gain or loss to the extent the
cost of the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.



BLACKROCK HEALTHCARE FUND, INC.                                  APRIL 30, 2007



Notes to Financial Statements (continued)


(d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

(e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Dividends from foreign securities where the ex-dividend date may have passed
are subsequently recorded when the Fund has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

(f) Prepaid registration fees--Prepaid registration fees are charged to
expense as the related shares are issued.

(g) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

(h) Securities lending--The Fund may lend securities to financial institutions
that provide cash or securities issued or guaranteed by the U.S. government as
collateral, which will be maintained at all times in an amount equal to at
least 100% of the current market value of the loaned securities. The market
value of the loaned securities is determined at the close of business of the
Fund and any additional required collateral is delivered to the Fund on the
next business day. Where the Fund receives securities as collateral for the
loaned securities, the Fund typically receives the income on both the loaned
securities and the collateral and, as a result, the Fund's yield may increase.
Where the Fund receives cash collateral, it may invest such collateral and
retain the amount earned on such investment, net of any amount rebated to the
borrower. The Fund may receive a flat fee for its loans. Loans of securities
are terminable at any time and the borrower, after notice, is required to
return borrowed securities within five business days. The Fund may pay
reasonable finder's, lending agent, administrative and custodial fees in
connection with its loans. In the event that the borrower defaults on its
obligation to return borrowed securities because of insolvency or for any
other reason, the Fund could experience delays and costs in gaining access to
the collateral. The Fund also could suffer a loss where the value of the
collateral falls below the market value of the borrowed securities, in the
event of borrower default or in the event of losses on investments made with
cash collateral.

(i) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes - an interpretation of FASB Statement No.
109." FIN 48 prescribes the minimum recognition threshold a tax position must
meet in connection with accounting for uncertainties in income tax positions
taken or expected to be taken by an entity, including mutual funds, before
being measured and recognized in the financial statements. Adoption of FIN 48
is required for the last net asset value calculation in the first required
financial statement reporting period for the fiscal years beginning after
December 15, 2006. The impact on the Fund's financial statements, if any, is
currently being assessed.

In September 2006, "Statement of Financial Accounting Standards No. 157, Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS
157 and its impact on the Fund's financial statements, if any, has not been
determined.

In addition, in February 2007, the Financial Accounting Standards Board issued
"Statement of Financial Accounting Standard No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities" ("FAS 159"), which is effective
for fiscal years beginning after November 15, 2007. Early adoption is
permitted as of the beginning of a fiscal year that begins on or before
November 15, 2007, provided the entity also elects to apply the provisions of
FAS 157. FAS 159 permits entities to choose to measure many financial
instruments and certain other items at fair value that are not currently
required to be measured at fair value. FAS 159 also establishes presentation
and disclosure requirements designed to facilitate comparisons between
entities that choose different measurement attributes for similar types of
assets and liabilities. At this time, management is evaluating the implications
of FAS 159 and its impact on the Fund's financial statements, if any, has not
been determined.

(j) Reclassification--U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the
current year, $5,005,799 has been reclassified between undistributed net
realized capital gains on investments and accumulated net investment loss as a
result of permanent differences attributable to net operating losses, foreign
currency transactions, and foreign taxes paid. This reclassification has no
effect on net assets or net asset values per share.

2. Investment Advisory Agreement and Transactions with Affiliates:
On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates, with BlackRock, Inc.
to create a new independent company. Merrill Lynch has a 49.8% economic
interest and a 45% voting interest in the combined company and The PNC
Financial Services Group, Inc. ("PNC"), has approximately a 34% economic and
voting interest. The new company operates under the BlackRock name and is
governed by a board of directors with a majority of independent members.

On August 15, 2006, shareholders of the Fund approved a new Investment
Advisory Agreement with BlackRock Advisors, Inc., an indirect, wholly owned
subsidiary of BlackRock, Inc., which was reorganized into a limited liability
company and renamed BlackRock Advisors, LLC. The new Investment Advisory
Agreement between the Fund and the Manager became effective on September 29,
2006. Prior to September 29, 2006, MLIM was the Fund's manager. The general
partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned
subsidiary of Merrill Lynch, which is the limited partner. The Fund also has
entered into separate Distribution Agreements and Distribution Plans with FAM
Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates
("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary
of Merrill Lynch Group, Inc., and BDI is an affiliate of BlackRock, Inc.

The Manager is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Fund. For such services, the Fund
pays the Manager a monthly fee at an annual rate of 1.0% of the average daily
value of the Fund's net assets. In addition, the Manager has entered into a
sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an
affiliate of the Manager, under which the Manager pays the Sub-Adviser for
services it provides a monthly fee at an annual rate equal to a percentage of
the management fee paid by the Fund to the Manager. Prior to September 29,
2006, MLIM had a Sub-Advisory Agreement with Merrill Lynch Asset Management
U.K. Limited ("MLAM U.K."), an affiliate of MLIM.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays each Distributor
ongoing service and distribution fees. The fees are accrued daily and paid
monthly at annual rates based upon the average daily net assets of the shares
as follows:


                                             Service       Distribution
                                                 Fee                Fee

Investor A                                      .25%                 --
Investor B                                      .25%               .75%
Investor C                                      .25%               .75%
Class R                                         .25%               .25%


Pursuant to sub-agreements with each Distributor, broker-dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch and an affiliate of each Distributor, provide
shareholder servicing and distribution services to the Fund. The ongoing
service fee compensates the Distributor and each broker-dealer (including
MLPF&S) for providing shareholder servicing to Investor A, Investor B,
Investor C and Class R shareholders. The ongoing distribution fee compensates
each Distributor and the MLPF&S for providing shareholder servicing and
distribution-related services to Investor B, Investor C and Class R
shareholders.

For the year ended April 30, 2007, FAMD, the Fund's sole Distributor until
September 29, 2006, and BDI earned underwriting discounts and direct
commissions, and MLPF&S and BDI earned dealer concessions on sales of the
Fund's Investor A Shares as follows:


                                     FAMD         MLPF&S            BDI

Investor A                      $   2,517     $   31,105        $   281


For the year ended April 30, 2007, MLPF&S received contingent deferred sales
charges of $79,166 and $36,002 relating to transactions in Investor B and
Investor C Shares, respectively. Furthermore, MLPF&S received contingent
deferred sales charges of $12,030 relating to transactions subject to front-
end sales charge waivers in Investor A Shares.

The Manager maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to shareholder
inquiries and processing transactions based upon instructions from
shareholders with respect to the subscription and redemption of Fund shares.
During the period September 29, 2006 to April 30, 2007, the following amounts
have been accrued by the Fund to reimburse the Manager for costs incurred
running the call center, which are a component of the transfer agent fees in
the accompanying Statement of Operations.

 * In September 2006, certain brokerages, including a wholly
   owned subsidiary of Merrill Lynch, entered into a remediation
   agreement with a regulatory organization, which among other
   things, permitted certain shareholders of Investor B Shares to
   convert their shares into the Fund's Investor A Shares. As a
   result, a wholly owned subsidiary of Merrill Lynch supplemented
   the Investor A Share purchase by approximately $61,000.

The Fund, along with certain other funds managed by the Manager and its
affiliates, is a party to a $500,000,000 credit agreement with a group of
lenders. The Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund
may borrow up to the maximum amount allowable under the Fund's current
prospectus and statement of additional information, subject to various other
legal, regulatory or contractual limits. On November 22, 2006, the credit
agreement was renewed for one year under substantially the same terms. The
Fund pays a commitment fee of .06% per annum based on the Fund's pro rata
share of the unused portion of the credit agreement. Amounts borrowed under
the credit agreement bear interest at a rate equal to, at each fund's
election, the federal funds rate plus .35% or a base rate as defined in the
credit agreement. The Fund did not borrow under the credit agreement during
the year ended April 30, 2007.

Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Directors
of BlackRock Healthcare Fund, Inc.:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of BlackRock Healthcare Fund, Inc.
(formerly Merrill Lynch Healthcare Fund, Inc.) as of April 30, 2007, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Fund is not required to have, nor were we engaged to
perform, an audit of its internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Fund's internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
as well as evaluating the overall financial statement presentation. Our
procedures included confirmation of securities owned as of April 30, 2007, by
correspondence with the custodian and brokers; where replies were not received
from brokers, we performed other auditing procedures. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
BlackRock Healthcare Fund, Inc. as of April 30, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and its financial highlights for each
of the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

           the end of the period covered by this report, that applies to the
           registrant's principal executive officer, principal financial
           officer and principal accounting officer, or persons performing
           similar functions.  A copy of the code of ethics is available
           without charge at www.blackrock.com.

Item 3 -   Audit Committee Financial Expert - The registrant's board of
           directors has determined that (i) the registrant has the following
           audit committee financial experts serving on its audit committee and
           (ii) each audit committee financial expert is independent: (1)
           Ronald W. Forbes, (2) Richard R. West, and (3) Edward D. Zinbarg
           (retired as of December 31, 2006).

Item 4 -   Principal Accountant Fees and Services

           (a) Audit Fees -         Fiscal Year Ended April 30, 2007 - $36,500
                                    Fiscal Year Ended April 30, 2006 - $36,500

           (b) Audit-Related Fees - Fiscal Year Ended April 30, 2007 - $0
                                    Fiscal Year Ended April 30, 2006 - $0

           (c) Tax Fees -           Fiscal Year Ended April 30, 2007 - $6,100
                                    Fiscal Year Ended April 30, 2006 - $6,000

           The nature of the services include tax compliance, tax advice and

           (e)(1) The registrant's audit committee (the "Committee") has
           adopted policies and procedures with regard to the pre-approval of
           services.  Audit, audit-related and tax compliance services provided
           to the registrant on an annual basis require specific pre-approval
           by the Committee.  The Committee also must approve other non-audit
           services provided to the registrant and those non-audit services
           provided to the registrant's affiliated service providers that
           relate directly to the operations and the financial reporting of the
           registrant.  Certain of these non-audit services that the Committee
           believes are a) consistent with the SEC's auditor independence rules
           and b) routine and recurring services that will not impair the
           independence of the independent accountants may be approved by the
           Committee without consideration on a specific case-by-case basis
           ("general pre-approval").  However, such services will only be
           deemed pre-approved provided that any individual project does not
           exceed $5,000 attributable to the registrant or $50,000 for all of
           the registrants the Committee oversees.  Any proposed services
           exceeding the pre-approved cost levels will require specific pre-
           approval by the Committee, as will any other services not subject to
           general pre-approval (e.g., unanticipated but permissible services).
           The Committee is informed of each service approved subject to
           general pre-approval at the next regularly scheduled in-person board
           meeting.

           (g) Fiscal Year Ended April 30, 2007 - $2,711,583
               Fiscal Year Ended April 30, 2006 - $3,439,633

           (h) The registrant's audit committee has considered and determined
           that the provision of non-audit services that were rendered to the
           registrant's investment adviser and any entity controlling,
           controlled by, or under common control with the investment adviser
           that provides ongoing services to the registrant that were not
           pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
           Regulation S-X is compatible with maintaining the principal
           accountant's independence.

           Shareholders who wish to recommend a nominee should send nominations
           which include biographical information and set forth the
           qualifications of the proposed nominee to the registrant's

           (17 CFR 270.30a-3(d)) that occurred during the second fiscal quarter
           of the period covered by this report that have materially affected,
           or are reasonably likely to materially affect, the registrant's
