I don't know which companies, if any, offer genetic testing that could provide valuable information about your situation. Buy please research that so, when you have surgery, tissue samples will be held for submission to a genetics testing firm. I'm a big believer in using any avenue to gain valuable information and the clinical biopsies and such, while important, can't measure every variable.

Also is it possible to make an appointment with another oncologist in your area while you wait for an opening at Mayo? You can always cancel an appointment if you need to and someone else will be grateful to grab it who also might be dealing with cancer for the first time and otherwise unable to see someone fast.
