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. In a special
report on cancer and blacks, the organization said blacks are usually diagnosed
with cancer later than whites, and they are more likely to die of the
disease. This could be because of unequal (不平等的) access to
medical Care. Because blacks are more likely to have other diseases as well, and
perhaps because of differences in the biology (生物学) of the cancer itself, the
report added. "In general, black Americans have less hope of
surviving five years after diagnosis than whites for all cancer sites and all
stages of diagnosis." the report said. "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 cancer
society said blacks should be encouraged to get check-ups (体格检查) earlier, when
cancer is more treatable. And it said more research is needed to see if
biological differences play a role. "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. But it also noted a drop in cancer death
rates. "Cancer death rates in both sexes for all sites combined
have dropped greatly among black Americans since 1992, as have incidence rates
(发生率)," said the report.
