The report is timely as the link between alcohol and cancer is well established. Few would dispute the generally adverse effects of alcohol consumption on cancer risk and overall health with excessive levels of intake. More controversy exists at light-to-moderate levels of intake, such as not exceeding 2 drinks per day for men or 1 drink per day for women. Cancer risk may be the biggest concern in the low-moderate range of drinking as about one-quarter of cancer cases attributable to alcohol consumption arise in those consuming two or fewer alcoholic drinks daily. In moderate alcohol consumers, four modifying factors merit consideration, tobacco use, drinking frequency, whether drinking is with meals or on an empty stomach, and beverage type.
