The risk of death from breast cancer before age 70 among Canadian women increases with each daily standard drink. Relative to non-drinkers there is an estimated 13% increase in risk for women who have 1 standard drink per day on average, 27% risk increase at 2 drinks, 52% increase at 3-4 drinks, 93% at 5-6 drinks, and 193% risk increase at 7+ drinks. A standard drink is the equivalent alcohol content of a 5oz glass of wine. For medical providers and public health agencies concerned with cancer, stroke and diabetes, addressing risky alcohol use is critical. People who are addicted to alcohol make up only a minority of those at risk.
