The more alcohol you drink, the more you could be increasing your risk of colon cancer. That's according to a study at Brigham and Women's Hospital and Harvard Medical School.
Together, researchers analyzed data from nearly a half million people in eight studies, and they found those who drank the most were at the highest risk. They also found a stronger risk among heavy drinkers who were thin compared to those who were more heavy-set.
Beer, wine, and liquor all seemed to have a similar impact on cancer risk. So, what's heavy drinking? Researchers called it three or more drinks a day.
On the other hand, previous studies have shown that moderate consumption, up to two drinks a day, is thought to provide some health benefit, even lowering the risk of heart disease.
