Larynx Cancer Types
Several types of cancer form in these two areas. About 95 percent of these cancers start from squamous cells. Squamous cell cancer is slow growing. Smoking and heavy alcohol drinking usually cause the changes. The cells are then considered "pre-cancers". Most pre-cancers will not develop into cancer. If the causes, such as smoking or drinking stop, the pre-cancers usually go away.
However, some pre-cancers do grow into cancers. The earliest form is called carcinoma in situ (CIS). A CIS has not spread to other parts of the body. Some will go away by themselves. Others can be cured by stripping or cutting away the cell's lining. Some are destroyed by radiation therapy. If CIS is not treated, it can spread.
