What is parotid gland cancer?

The parotid gland is the largest of the major salivary glands and the most likely to develop cancer. It is located in the cheek in front of the ear. The smaller major salivary glands are the sublingual salivary glands, which are under each side of the tongue, and the submandibular glands, which are under and inside the lower jaw bone (the mandible), toward the back. There are also a number of small minor salivary glands in the mouth. The salivary glands produce saliva, which helps keep the mouth moist and aids in digestion.

Several different types of cells can be found in salivary glands; as a result, several different types of cancers can develop. Some are slow growing; others are more aggressive.

The risk of parotid and other salivary gland cancers seems to increase following radiation exposure. The risk also tends to go up with age; salivary gland cancers are most common in people age 55 or older. Overall, salivary gland cancers are quite rare, occurring in approximately two in every 100,000 people each year in the United States (Source: ACS).

Parotid gland cancer is frequently curable, especially when caught in early stages. Treatment is typically surgery, which may be followed by radiation therapy. Chemotherapy can be effective in treating later stage cancers.

Emergencies related to parotid gland cancer are rare; however, parotid gland cancers are known to cause serious symptoms. Also, parotid gland cancers that are caught early have a better chance of cure than cancers that are not detected until later. Seek prompt medical care if you notice swelling in your cheek or jaw, inside your mouth, or in your neck, especially if it does not go away within a week or two. Also seek medical care for facial weakness or numbness, trouble swallowing or opening your mouth, or persistent pain in your face.
