Alcohol raises risk of breast cancer return

Post-menopausal women who have three to four alcoholic beverages a week of any sort have a significantly higher risk that their breast cancer will come back, researchers said in the United States on Thursday.

They said women who have been diagnosed with breast cancer should consider limiting alcohol consumption to less than three drinks a week, especially if they are overweight or obese.

"We didn't find any increased risk in women who consumed less than half a drink per day. There was no association at all with breast cancer recurrence," said Marilyn Kwan, a research scientist at Kaiser Permanente in Oakland, California, who presented her findings at the American Association for Cancer Research San Antonio Breast Cancer Symposium.

Other studies have shown that alcohol use can increase the chances a woman will develop breast cancer, but few studies have looked at the role of alcohol consumption in women who already have had a breast cancer diagnosis.

Kwan and colleagues studied 1,900 women and followed them for 8 years.
