What should people know about cancer of the oral cavity?
The oral cavity is made up of the mouth, pharynx and salivary glands. Almost four percent of cancers occur in the oral cavity. The tongue, floor of the mouth, gums, lip, tonsil and lower pharynx are where most oral cavity cancers occur. Cancer of the salivary glands is relatively rare. However, when it does occur, it most frequently starts in the parotid gland.
