What happen if u developed a warthin tumor in the parotid gland?

You're be relieved: It's benign and far less troublesome than most other causes of parotid masses.

Needs to come out: While benign, you don't want masses growing in your parotid gland. The nerve the moves that half of the face (aptly named the facial nerve) runs through the middle of the gland and it is always easier to take out smaller parotid masses than bigger ones. Discuss this with your ent, who likely will suggest surgical removal of the mass and part- though not all- of the parotid gland.
