Drink alcohol in moderation, if at all

If you choose to drink alcohol, do so in moderation. For healthy adults, that means up to one drink a day for women of all ages and men older than age 65, and up to two drinks a day for men age 65 and younger.

Alcohol does have health benefits in some people — for instance, consuming a drink a day can reduce your risk of heart disease. But it also increases the risk of certain cancers, including those of the mouth and throat.

While it isn't clear whether drinking alcohol can cause cancer recurrence, it can increase your risk of a second primary cancer.

Weigh the risks and benefits of drinking alcohol and talk it over with your doctor.
