Study subjects: 40,000 postmenopausal women

Location of study: U.S.

Results: A study by the Cancer Prevention Institute of California found that women using hormone therapy who also consumed a moderate amount of alcohol had an increased risk of breast cancer.

Women using hormone therapy who consumed two or more drinks per day approximately doubled their risk over those who used hormone therapy alone.

Significance: The research provides more insight into the link between alcohol and breast cancer.
