It seems like cancer is in the news more than ever these days, and the health benefits of light alcohol consumption have been touted for years (even claims that alcohol improves brain health). However, new research indicates that even light alcohol consumption will increase your risk from cancer.
Scientists have known for a hundred years about the link between alcohol consumption and cancer. A study from Paris in 1910 showed that 80 percent of patients with cancer of the esophagus or gastric track were alcoholics. More recently, scientists have found correlations between alcohol consumption and cancer of the mouth, pharynx, larynx, esophagus, liver, large bowel, and even the breasts. Yet lab experiments have always failed to show the effects in animals that investigators knew to be true in humans.
It seems past studies used too much alcohol -- in concentrations of 20 percent -- and the animals just wasted away while showing no tumor growth. But when Gu used concentrations of one percent -- about one to two drinks per day in humans -- to study blood vessel growth, he detected stimulated tumor growth in both chick embryos and mice. ...
Gu's findings, now confirmed by other scientists, are evidence of what many have long suspected -- alcohol, even in moderation, increases cancer risk.
Therefore I'll continue my policy of teetotaling.
