Tobacco usage: Head and neck cancers include cancers involving the throat, tongue, mouth, nose , and sinuses. Cigarette smoking is closely associated with throat cancer and chewing tobacco causes cancer in the mouth. Nasal and sinus cancers happen more often because of genetic predisposition rather than some external irritant like smoke.
