Alcohol Can Increase Your Cancer Risk, Researchers Find

The world's oldest and largest cancer research association "found excessive levels of alcohol consumption increase the risk for six different types of cancer," reports CBS News: "Some of this is happening through chronic inflammation. We also know that alcohol changes the microbiome, so those are the bacteria that live in your gut, and that can also increase the risk," Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, recently said on "CBS Mornings."

But how much is too much when it comes to drinking? We asked experts what to know. "Excessive levels of alcohol" equates to about three or more drinks per day for women and four or more drinks per day for men, Gounder said... Other studies have shown, however, there is no "safe amount" of alcohol, Gounder said, particularly if you have underlying medical conditions. "If you don't drink, don't start drinking. If you do drink, really try to keep it within moderation," she said.

Dr. Amy Commander, medical director of the Mass General Cancer Center specializing in breast cancer, told CBS News alcohol is the third leading modifiable risk factor that can increase cancer risk after accounting for cigarette smoking and excess body weight. [Other factors include physical inactivity — and diet]. "There really isn't a safe amount of alcohol for consumption," she said. "In fact, it's best to not drink alcohol at all, but that is obviously hard for many people. So I think it's really important for individuals to just be mindful of their alcohol consumption and certainly drink less."
The article also includes an interesting statistic from the association's latest Cancer Progress Report: from 1991 to 2021 there's been a 33% reduction in overall cancer deaths in the U.S. That's 4.1 million lives saved — roughly 136,667 lives saved each year.

"So that is hopeful," Commander said, adding that when it comes to preventing cancer, alcohol is just "one piece of the puzzle."
