Light/moderate drinking linked to increased risk of some cancers in women

Even light and moderate drinking (up to one drink a day for women and up to two drinks a day for men) is associated with an increased risk of certain alcohol related cancers in women and male smokers, suggests a large study published by The BMJ today.

The study, which involved almost 136,000 people, found women who drank the equivalent of a glass of wine a day over a 30-year period were 13% more likely to develop one of the alcohol-related cancers (breast cancer being the most common) than women who didn’t drink at all.

The study found low to moderate drinking increased the risk of certain types of cancers already thought to be linked to alcohol, but only among women or people who smoked. Men who didn’t smoke and drank moderately had no increased risk of any type of cancer.
