Call it liquor, alcohol, or booze, but this substance's scientific name is ethyl alcohol. It's a chemical typically made from fermenting sugars (like those from grapes) or starches (such as potatoes or rice) with yeast.
Part of the reason alcohol is dangerous is that it irritates tissues, making it easier for carcinogens (cancer-causing compounds) to sneak in and cause DNA damage in the body.
Scientists have shown time and time again that drinking alcohol can contribute to several different kinds of cancer in humans. The dose is important too; the more you drink, the greater your risk of developing different kinds of cancers, including head, neck, throat, liver, breast, and colon.
A worldwide study of drinkers in 195 countries published in 2018 found that no matter where people live, heavier drinkers are more likely to develop cancer, and they're also more likely to die from cancer and many other causes.
