Salivary Gland Tumours

Most salivary gland tumours are benign - they are not cancerous and do not spread to other parts of the body. These tumours are seldom life-threatening.

Pleomorphic adenomas are the most common type of salivary gland tumour.

Parotid tumours often cause swelling in the face or jaw that usually isn't painful. Other symptoms include numbness, burning or prickling sensations in the face, or a loss of facial movement.

Not all salivary gland swellings are malignant; most of them are benign. Salivary gland swelling is also commonly associated with mumps. Swelling happens in parotid glands on both sides of the face, giving the appearance of "chipmunk cheeks." Viral infections such as the flu and others can also cause swelling of the salivary glands.
