Alcohol Consumption After Breast Cancer Diagnosis May Increase Recurrence Risk
Alcohol consumption following diagnosis of early-stage breast cancer may increase risk of recurrence of cancer but not total mortality risk
In the Life After Cancer Epidemiology (LACE) study, 1,897 participants diagnosed with early-stage breast cancer between 1997 and 2000 and recruited on average 2 years post-breast cancer diagnosis were evaluated for the association between alcohol intake and breast cancer recurrence and death. The women, who were generally light drinkers, were followed for an average of 7.4 years. The study reported an increase in risk of breast cancer recurrence and breast cancer death, but no effect on total mortality, to be associated with consumption of 3 to 4 or more drinks per week when compared with women not drinking following their cancer diagnosis.
Because of conflicting results among studies on this topic, further research will be needed to determine the extent to which alcohol following a diagnosis of breast cancer may relate to subsequent disease and death.
