Alcohol and breast cancer risk

“Drinking alcohol increases the risk of breast cancer in women and heavy drinking increases the risk in men.

The more alcohol a woman consumes the greater the risk, with no lower threshold.

Alcohol is metabolised into acetaldehyde, a cancer-causing compound. This occurs primarily in the liver but also in breast tissue.

Alcohol increases levels of circulating hormones including oestrogen, which increases breast cancer risk.”
