Possible Link Identified Between Hereditary Cancer Genes and Increased Risk of Cancer From Alcohol
Medical News Today

In laboratory experiments conducted on human cell lines at the Johns Hopkins Kimmel Cancer Center, scientists have shown that people carrying certain mutations in two hereditary cancer genes, BRCA2 and PALB2, may have a higher than usual susceptibility to DNA damage caused by a byproduct of alcohol, called acetaldehyde. The scientists say they suspect that the two genes in their normal forms evolved to protect cells against the damaging effects of acetaldehyde, which can lead to cancer. While the scientists caution that the research is preliminary, they say their findings suggest that studies on disease risk factors should take into account these particular genetic variations and the use of alcohol.
