There is strong causal evidence that alcohol contributes to cancer.

Good. A lot of the public really isn't aware that there is strong causal evidence that alcohol contributes to cancer.

As the report notes, we have causal evidence that alcohol causes at least 7 types of cancer. It is the third largest preventable cause of cancer behind tobacco and obesity.

Alcohol contributes to 1 in 6 breast cancers in women.

The risk increases with higher consumption. But for breast, mouth, and throat cancers the risk is elevated even with 1 or fewer drinks per day.
