Good evening, welcome to J.A. Lois. Unfortunatly surgery is the treatment of choice in benign salivary gland tumors. Except for radiation therapy, there are no non-surgical treatments currently available or being tested. I wish I could offer a more positive answer, but I'm happy to answer this, or any other question you may ask. Goodnight.
I hope my answer is helpful. If you have more questions, just ask! I am happy to help. If not, please click "accept" so I may receive credit for my work.
Positive feedback and a bonus is appreciated when you feel I've earned it. Thank you, Christy
