Abstract
For most cancers, black Americans or Americans of African heritage have the highest cancer mortality rates and the worst survival of any population ( 1 ). This fact has been a concern for nearly 40 years ( 2 ). Although it is incontrovertible that there are racial disparities in cancer incidence and mortality, the reasons for the disparities are not as clear and indeed are controversial. Some have suggested that they are due to racial differences in biology ( 3 , 4 ). Others have suggested that socioeconomic and cultural influences are to blame ( 5 ).
