Lip cancer is the most common form of oral cancer, and affects mostly men. There are two types of lip cancer: squamous cell and basal cell. The most common type of lip cancer begins in the squamous cells, the thin, flat cells that line the lips and mouth. Lip cancer symptoms are very similar to those of other types of oral cancer. It can often be mistaken for a cold that won’t go away, or a persistent toothache. Other symptoms and signs include, A sore in the mouth that does not heal, Persistent mouth pain, A lump or thickening in the cheek, A white or red patch on the gums, tongue, tonsil, or lining of the mouth, A sore throat or feeling that something is caught in the throat that does not go away.
The study was commissioned by the Israel Dental Association and directed by Avi Zini of the community dentistry department at the Hebrew University-Hadassah School of Dental Medicine. The study included examination of the incidence of oral cavity cancers in Israel from 1970 to 2006. Of the 11,843 Israelis who developed oral cancers during the period studied, salivary gland cancer was the third most common (at 16.2 percent) after lip cancer and throat cancer. Most oral cancer patients were over 70, with only 2.7 percent under the age of 20.
