A case-control study on 177 pre menopausal and 216 post menopausal breast cancer patients diagnosed in the southern Swedish Health Care Region between 1980 and 1981 and 195 pre menopausal and 254 post menopausal controls randomly chosen from the same population by means of a computerized population register was used to estimate the relation between alcohol, cigarettes and the risk for breast cancer. Cigarette smoking was significantly related to the risk for breast cancer neither among pre nor among post menopausal women. Consumption of wine and spirits appeared to be protective among post but not among pre menopausal women; RR=0.4 (0.3-0.7) and RR=0.6 (0.4-0.8) resp for post menopausal women. The consumed quantities were moderate.
