A study published in JAMA shows blacks, especially black women, have a higher risk of having one or more large colon polyps when compared with whites. Lead author Dr. David A. Lieberman, professor of medicine at Oregon Health and Sciences University, says the results are so striking he is recommending "more intensive public education efforts among black Americans" about colon cancer. The study shows black women are 62% more likely and black men 16% more likely than their white counterparts to have such polyps.
