Cancer of the head and neck region represents approximately three percent of all cancers diagnosed in the United States each year. Cancers in this part of the body have been strongly associated with the use of both tobacco and alcohol. Presenting symptoms depend on the site of involvement; however, they can include hoarseness, sore throat, ear pain, difficulty chewing and swallowing, and even potentially, difficulty breathing.
There are many types of cancer that can arise in the head and neck region, but by far the most common type is squamous cell carcinoma, which arises from the lining of the mouth and throat. That correlates with the fact that those are the areas which are exposed to the highest concentration of tobacco products like smoke from cigarettes and chewing tobacco.
