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．
