19. Drinking too much
We all enjoy a drink from now and then, but if one drink translates to four or more, we have a serious problem here. Having more than two alcoholic beverages per day increases your cancer risk significantly. The American Cancer Society even noted that overdrinking is strongly associated with a greater risk of liver, breast, throat, and colon cancer.
Avoid ordering that third alcoholic drink at all costs!
