i am 54 years old weigh 88.50 kgs height 5foot 8inches. iam under medication for diabetes and cholestorol for last two years and is under control. i have a solid painless lump on the left neck which after taking a cat scan recently the doctors have diagonised it as parotid tumours which mostly are benign but can be cancerous also. they have suggested for surgery to remove the gland . however they stated that upon doing the surgery there might be a ten percent chance of facial paralysis . is there any other way to cure this besides surgery
