The researchers found that even moderate amounts of alcohol (66 grams of vodka a day) results in 6000 of cancer deaths in the U.S. alone.
Timothy Naim from Boston University and his team found that alcohol is responsible for 20 000 000 cancer deaths, or 3.5% of all deaths in cancer.
In men, the alcohol generally leads to cancer of the mouth, throat, esophagus, and for women, alcohol consumption associated with breast cancer.
Evidence of excessive alcohol consumption due to cancer, much more than the relationship of occurrence of the disease with moderate drinking.
But the risk from the use of moderate doses should also be taken seriously, the study Neumann.
Naim expressed doubts about the reliability of studies showing the benefits of alcohol for moderate drinkers. He said that these studies did not comply with generally accepted scientific standards, which require a randomized control group of non-drinking people.
