Hi Panhandle,
I want to welcome you to the forum and tell you how sorry I am that you are having these health problems.
I'm also sorry I can't help you as I don't know anything about the tumors but if it were me, I wouldn't be satisfied with the doctors. I would do some searching and get some more opinions.
We sometimes have to be our own advocates for our health problems.
I'm wishing you all the best.
Linda
