U.S. Blacks Hard-hit by Cancer Death rates for cancer are falling for all Americans, but black Americans are still more likely to die of cancer than whites, the American Cancer Society said Monday. This could be because of unequal access to medical care, because blacks are more likely to have other diseases as well, and perhaps because of differences in the biology of the cancer itself, the report added. In describing cancer statistics for black Americans, this report recognizes that many of the differences associated with race may be caused by unfair social and economic differences and unequal access to medical care. The new statistics emphasize the continuing importance of wiping out these unfair social differences through public policy and education efforts, the organization said in a statement.
