I have parotid cancer. I was told it was benign but instead it was malignant. Nt all of it was removed 8 months ago. It is now causing symptoms from base of skull and twitching R eye and mouth. I have painful swelling R lower face and in R neck. I am told it is in masseter between upper and lower teeth too. I have been told they cannot re operate. I have not had any radiation or chemo. Has anyne heard of other treatments?
