CANCER RESEARCHResearchers too DNA from cancerous cells in patients with lung cancer (including some who had never smoked cigarettes) and measured mutations in the p53 gene, the most frequently mutated gene in human cancer. Among the smokers who also drank alcohol, 76% had p53 mutations in their cancer cells, as compared with 42% of the smokers who did not drink alcohol. Scientists hypothesize that alcohol interferes with the body's ability to convert carcinogenic chemicals in smoke into more benign substances that it can eliminate. Alcohol may also disrupt the body's ability to repair DNA that has been damaged by the carcinogens, researchers suggest.(U.S. News, THE FEMALE PATIENT, August 1999) --> return to menu / back ...
