We know there are certain things that can increase a person's risk of cancer, such as smoking. But it turns out even drinking a small amount of alcohol can lead to cancer.

A new study from the American Society of Clinical Oncology found that between five and six percent of new cancer and cancer deaths can be attributed to alcohol. 

“People typically don’t associate drinking beer, wine, and hard liquor with increasing their risk of developing cancer in their lifetimes,” Bruce Johnson, the society’s president, said in a statement.

The society found that drinking alcohol led to an increased risk in many types of cancer, including oropharyngeal and larynx cancer, esophageal cancer, hepatocellular carcinoma, breast cancer, and colon cancer. 

“The importance of alcohol drinking as a contributing factor to the overall cancer burden is often under-appreciated. In fact, alcohol drinking is an established risk factor for several malignancies,” the researchers found. “In the United States, it has been estimated that 3.5% of all cancer deaths are attributable to drinking alcohol.”

Another study earlier this year found that people who drank four pints of beer or five glasses of wine per week were actually at greater risk of brain deterioration than those who did not. These studies seem to contradict the view of many that a glass or two of alcohol a day could actually improve a person's health.

Just more proof that alcohol is worse than marijuana, despite what America's drug laws will tell you.
