Smoking and obesity are known risk factors for cancer -- but could your nightly glass of wine also be increasing your chances for developing the disease?
A new study from Boston University Medical Center finds twenty thousand cancer deaths each year are caused by alcohol consumption. Breast cancer has the most alcohol-related cases, accounting for six thousand deaths each year. Cancer of the mouth, throat, esophagus and liver are also related to drinking alcohol. And while the researchers found the risk for cancer increased the more a patient drank -- one out of three reported having just a little more than one serving of alcohol each day.
