A case-control study was conducted in Italy and Switzerland between 1992 and 2000 on 527 cases of laryngeal cancer and 1,297 hospital controls. The risk of laryngeal cancer steadily decreased from 3 years after stopping smoking. Some decline in risk was observed only 20 years or more after stopping drinking.
