Pleomorphic adenoma is the most frequent of the tumors to affect
the principal salivary glands like the parotid (located in the mouth, just under the ear) or the minor salivary glands near the palate, at the base of the tongue, inside the cheeks or the upper lip. Pleomorphic adenomas generally don't carry a risk, only 2% of them evolve into a cancerous tumor. Nevertheless, a very large pleomorphic adenoma can be removed surgically if it proves to be too troublesome.
