A study of nearly 1.3 million British women offers yet more evidence that moderate alcohol consumption increases the risk of a handful of cancers. British researchers surveyed middle-aged women at breast cancer screening clinics about their drinking habits, and tracked their health for seven years.A quarter of the women reported no alcohol use. Nearly all the rest reported fewer than three drinks a day; the average was one drink a day. Researchers compared the lightest drinkers — two or fewer drinks a week — with people who drank more.
Each extra drink per day increased the risk of breast, rectal and liver cancer, University of Oxford researchers reported Tuesday in the Journal of the National Cancer Institute. The type of alcohol — wine, beer or liquor — didn't matter.
That supports earlier research, but the new wrinkle: Alcohol consumption was linked to esophageal and oral cancers only when smokers drank.
Also, moderate drinkers actually had a lower risk of thyroid cancer, non-Hodgkin's lymphoma and renal cell cancer.
