It begins as a lump or mass on the side of the face in front of the ear, at or above the jawbone. If the growth is slow and the lump is painless it is likely to be benign (80% of cases). If the area is painful or numb (nerve paralysis) it may be malignant (20% of cases) and the prognosis is poor with average survival of 2.7 years and a 10-year survival of 14–26%. It affects between 1 to 3 people per 100,000 each year in the Western world. What I am referring to is a parotid gland tumor (PGT), also known as salivary gland tumor (SGT).
Parotid tumors have not received much attention until recently.
