U.K. study links wine to cancer risk in women

Researchers from Southampton Hospital in the United Kingdom say that having one bottle of wine each week increases the risk of cancer by the same amount as smoking up to ten cigarettes. They found the "cigarette equivalent" of one bottle of wine is five cigarettes for men or ten for women on a weekly basis.

Men were more likely to get gastrointestinal cancers from drinking, while the risk of breast cancer was greatest for women. The risk was much greater for both men and women who drink three bottles of wine per week.

Emergency room physician Dr. Huma Kausar discusses the study with Isiah Carey.
