CausesSalivary gland tumors are rare, accounting for less than 10 percent of all head and neck tumors. It's not clear what causes salivary gland tumors.
Doctors know salivary gland cancer occurs when some cells in a salivary gland develop mutations in their DNA. The mutations allow the cells to grow and divide rapidly. The mutated cells continue living when other cells would die. The accumulating cells form a tumor that can invade nearby tissue. Cancerous cells can break off and spread (metastasize) to distant areas of the bod

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.
