Alcohol and Cancer

Heavy boozing has been shown to up the risk for certain cancers, including breast, liver, mouth, and throat cancer. In fact, when researchers tracked the drinking habits and cancer risk of more than a million women, they found that up to 13% of cancer cases were tied to alcohol consumption, according to the NIAAA.

What’s the link? When alcohol is broken down in the body, its converted to a toxic chemical called acetaldehyde. Acetaldehyde can injure both the DNA and the proteins in the body and cause damage to your cells, Dr. Lebeda explains. Alcohol also generates free radicals, harmful compounds that cause cells to oxidize. That can sometimes cause healthy cells to grow out of control and become cancerous, Dr. Lebeda says.
