Parotid tumors are the most common type of salivary gland tumors, accounting for 80 to 85 percent of all salivary gland tumors. While most parotid tumors are noncancerous (benign), the parotid glands are where nearly 25 percent of cancerous (malignant) salivary gland tumors develop.

The parotid glands, located just in front of the ears on each side of the face, are the largest of the three sets of major salivary glands. They are responsible for producing saliva to aid in chewing and digesting food.

Parotid tumors may present a variety of characteristics. If you have a parotid tumor, you may notice a mass or swelling in your jaw area that may or may not be painful. If the tumor is malignant, it may also affect facial nerves, causing pain, numbness, a burning or prickling sensation, or loss of movement in the face.
