Drinking alcohol, even a light or moderate amount, increases the risk of several common cancers. The American Society of Clinical Oncology (ASCO) issued a statement identifying alcohol as a "definite" risk factor. "People typically don't associate drinking beer, wine with increasing their risk of developing cancer ", Dr. Bruce Johnson, the president of ASCO, said.
Indeed, a recent survey from the organization found that 70 percent of Americans didn't know that drinking alcohol is a risk factor for cancer. "However, the link between increased alcohol consumption and cancer has been firmly established," Johnson said. It's estimated that worldwide, about 5 percent of new cancers and 6 percent of cancer deaths each year are directly attributable to alcohol consumption.
