It’s well known that long term smoking can increase the incidence of lung cancer while it’s seldom known that smoking may also increase the risk of getting throat cancer. Actually smoking is the primary risk factor of throat cancer, which has been certified by the fact that 95 percent of patients who have treated in hospital had a history of smoking.
According to a research done in Finland, daily smokers over 30 pieces have higher risk of getting throat cancer than nonsmokers; the risk is decreased for people who quit smoking or have intermittent history of smoking.

2. Moderate alcohol drinking: alcohol can irritate mucous membranes and make mucous denatured. Long-term alcohol consumption may lead to cancerization.
3. Active treatment for throat disease such as chronic laryngitis, respiratory inflammation, and so on.
