Drinking alcohol can increase your risk of cancer because ethanol is itself a carcinogen on certain parts of the body, scientists have found.
Researchers said they found that when ethanol is broken down by the body, it can cause DNA damage that may lead to dangerous changes to the cells.
U.S team from the National Institute on Alcohol Abuse and Alcoholism in
Maryland, used human cells engineered to produce an enzyme that is
found in liver and
the cells to a concentration of alcohol similar to blood alcohol levels
attained after having a few drinks on a night out. The results confirmed that the alcohol (ethanol) was being converted to
acetaldehyde, causing DNA damage and switching on the cell's DNA repair
