Alcohol consumption increases risk of seven types of cancer, claim doctors

Posted November 09, 2017

In a statement released November 7 in the Journal of Clinical Oncology, ASCO said it has evidence identifying alcohol consumption as a definite cancer risk, citing 5 to 6 percent of new cancers and deaths related to cancer around the world as directly tied to alcoholic use.

For its research, ASCO reviewed earlier studied and made the conclusion that 5.5% of all of the new cancers as well as 5.8% of cancer deaths around the world could be attributed to alcohol.

LoConte also told the Times people who do drink alcohol don't have to totally stop, although that'd be the smartest move, but that "If you want to reduce your cancer risk, drink less".

As of 2013, about 73 per cent of Americans reported consuming alcohol, and almost 13 per cent described their consumption habits as binge drinking, according to a survey published in JAMA Psychiatry in August.

LoConte is the author of "Alcohol and Cancer", an American Society of Clinical Oncology special article.

The risk for heavy drinkers - defined as eight or more drinks a week for women and 15 or more a week for men, including binge drinkers - are multiples higher. Additionally, excessive alcohol use has also been found to negatively affect cancer treatment. The statement is meant to raise awareness about the strong link between alcohol and cancer.

The group warns that heavy drinkers have an increased risk of developing liver cancer, mouth cancer, throat cancer, colorectal cancers and cancer of the voicebox.

"It's good to look at where you are with diet and physical activity and look at places where you might improve and just start every day to take some simple steps to decrease your risk and improve your health", Bender said. "We don't have randomized trials, but sometimes when you start looking at the coherence of all the evidence, including the observational epidemiology, the lab studies, the mechanistic studies, you begin to see a picture and get more clarity". Overdoing it may lead to cancer.

Alcohol is classified as a carcinogen by the International Agency for Cancer Research.

"The evidence is very clear", she said.

To reverse the trend, ASCO suggests a number of measures to fight cancer deaths from alcohol, including by limiting sales through increased taxes and incorporating alcohol control strategies into cancer patients' care plans.
