Just one glass of wine, beer– or about 10 grams of alcohol– a day significantly increases the risk of breast cancer, according to a report by the American Institute for Cancer Research.
The alcohol consumption can lead to a five percent increased risk of cancer for pre-menopausal women and nine percent for post-menopausal women, according to the report.
“This suggests there is no level of alcohol use that is completely safe in terms of breast cancer,” said Anne McTiernan, a lead author of the report.
Both pre- and post-menopausal women can decrease the risk of breast cancer with hardcore exercise such as running or fast bicycling.
“With this comprehensive and up-to-date report the evidence is clear: Having a physically active lifestyle, maintaining a healthy weight throughout life and limiting alcohol – these are all steps women can take to lower their risk,” McTiernan said.
The report analyzed 119 studies, including data on 12 million women and 260,000 cases of breast cancer.
