Scientists at Georgia Health Sciences University identified a mutation in the p53 tumor suppressor gene that might underlie racial differences in breast and colon cancers. Black people with a specific genetic profile are more likely than whites and Asians with a different genetic profile to get breast or colorectal cancers at a young age, the researchers say. The researchers compared patients' normal genome from blood with tissue samples from tumors to identify the mutation.
