Just one alcoholic drink a day increases risk of breast cancer, study says
AKIPRESS.COM - Researchers have long known that having one too many cocktails might be associated with an increased risk of breast cancer.
Now, a new report from the World Cancer Research Fund and the American Institute for Cancer Research reveals just how much of a risk daily drinking might pose for both premenopausal and postmenopausal women, CNN reported.
Sipping an average of 10 grams of alcohol a day -- equivalent to a small glass of wine, an 8-ounce beer or 1 ounce of hard liquor -- is associated with a 5% increased breast cancer risk in premenopausal women and 9% increase in postmenopausal women, said Dr. Anne McTiernan, a lead author of the new report and a cancer prevention researcher at the Fred Hutchinson Cancer Research Center in Seattle.
"I was most surprised by the alcohol result, that risk increases at just one drink a day, on average," McTiernan said. "The increase with one drink a day was small ... but the risk goes up from there. So that's why AICR recommends no more than one alcohol drink a day for women to reduce risk for cancer."
Globally, breast cancer is the top cancer in women, in both the developed and developing worlds, according to the World Health Organization
