@pjdonn Hello and welcome to our Head and Neck group. That’s a big tumor. There are a lot of people here who have dealt with a parotid tumor and can likely help you out better than I. If you have a specific issue or problem please just start your own discussion which will result in better visibility to your concern.
In the meantime, make sure your doctors have experience in this particular tumor by flat out asking them, “What is your experience with Parotid tumors?” If the answer is zero, ask for a referral to someone or some place with experience. It is your life on the line.
As for nervous, that means you are smart. Get good help and you should do well. My word for you is “Courage.”
