Welcome @rogermcintire.

As you prepare for your upcoming appointment, I thought we could help you prepare a list of possible questions. Here's a few I found on Mayo Clinic's website:
What are my treatment options?
How will you check my response to treatment?
How likely is my condition to recur? What treatment options would be available in that case?
What follow-up tests will I need to monitor for recurrence?
I have other health conditions. How can I best manage them together?
Are there any restrictions that I need to follow?
Should I see a specialist? What will that cost, and will my insurance cover it?
Are there any brochures or other printed material that I can take with me? What websites do you recommend?

Roger, Do you already know that you will be getting immunotherapy as a treatment?
