ATLANTA - Risk of developing colorectal cancer is known to differ across ethnic and racial groups, and now an analysis of 26 studies, involving over 25,000 participants shows that some of these disparities might be explained by distinct patterns of genetic inheritance. A team of researchers, led by investigators at the University of Pittsburgh, present their findings today in Atlanta at the American Association for Cancer Research conference on The Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, being held November 27-30.
