Among women treated for early-stage breast cancer, those who consume three to four alcoholic drinks per week or more have a higher risk of breast cancer recurrence than non-drinkers. These results were presented at the 2009 San Antonio Breast Cancer Symposium.
Previous studies have reported that alcohol consumption increases the risk of developing breast cancer, but there has been limited information about whether alcohol influences breast cancer prognosis and survival.
To address this question, researchers evaluated information from the Life After Cancer Epidemiology (LACE) study. The study enrolled 1,897 women who were diagnosed with early-stage, invasive breast cancer between 1997 and 2000. Information about alcohol consumption was collected by questionnaire.
In a prepared statement, the lead researcher suggested that “women previously diagnosed with breast cancer should consider limiting their consumption of alcohol to less than three drinks per week, especially women who are postmenopausal and overweight or obese.”
