Us 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. 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 access to medical care,because blacks are more likely to have other diseases like diabetes as well,and perhaps because of differences in the biology of the cancer itself,the report added. "In general,African Americans have less likelihood 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 Mrican Americans,this report recognizes that socioeconomic disparities and unequal access to medical care may underlie many of the differences associated with race." The Cancer Society said blacks should be encouraged to get check-ups earlier,when cancer is more treatable,and it said more research was needed to see if biological differences play a role.
"The new statistics emphasize the continuing importance of eliminating these social disparities 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 declined substantially among African Amnericans since 1992,as have incidence rates,"said the report. "Increased efforts to improve economic conditions in combination with education about the relationship of lifestyle choices to cancer could further reduce the burden of cancer among African Americans."
About 36 million Americans describe themselves as black,representing about 12 percent of the population.
选项 Which may NOT be a reason for higher cancer death rates among US blacks?
A:Unequal access to medical care.
B:Greater probability of having other diseases.
C:Differences in the biology of the cancer.
D:Early diagnosis.
答案D
解析由文章第一段中“…but black Americans are still more likely to die of cancer than whites…”可知，美国黑人的癌症死亡率高于美国白人。故选B。
A、B、C三项在文章第三段中都被提及，用以说明美国黑人比白人有着更高的癌症死亡率的原因，而D项（早期诊断）是有助于降低癌症死亡率的。故选D。
由文章第六段中“The Cancer Society said blacks should be encouraged to get check-ups earlier , when cancer is more treatable…”可知，黑人被鼓励更早去做检查，因为癌症越早发现越有利于治疗。故选A。
文章第七段中提到，公共政策和教育有助于消除不平等的社会差异。故选C。
由文章倒数第三段的内容可知，自1992年以来，美国黑人的癌症死亡率下降了。故选D。
