Alcohol consumption is considered by the International Agency for Research on Cancer to be causally related to invasive breast cancer with a 7% to 10% increase in risk for each 10g alcohol consumed daily by adult women. However, the risk attributable to alcohol intake during adolescence and early adulthood remains inconclusive. It is the aim of this study ito evaluate the association of the of alcohol consumed before the first pregancy with the risks of breast cancer and proliferative benign breast disease, independent of drinking after first pregnancy.
