There are several pairs of salivary
glands in the mouth: in front of the ears (parotid glands), under the
jaw (submanibular glands) and under the tongue (subligual glands).
These all produce saliva, which is the lubricating fluid
found in the mouth. Saliva contains enzymes that begin the
process of digesting food as well as antibodies and other
substances that help prevent infections of the mouth and throat.
A tumor can form in any of these glands, but the most common location for cancerous tumors is in the parotid gland. Not every lump in a salivary gland is cancer, as many benign tumors and other conditions (such as infections and salivary gland stones) can also cause lumps. The exact cause of salivary gland cancer is unknown. In some cases, cancer may develop due to DNA damage after years of tobacco use or exposure to radiation. Heredity also may play a role in the development of salivary gland cancer.
Symptoms of a salivary tumor include:
