Welcome to the forum "Hap". I'm new to the forum myself, so I don't have any technical information to share with you. But, doing nothing, ie waiting/hoping for tumor shrinkage somehow just doesn't sit right with me. What are your doctors saying/recommending?

With all the other that's happened to you Happyguy looks like an appropriate username. You will find several others who share your upbeat attitude; they will all likely comment on your thread, offering their support.

You might as well create a signature line for the bottom of your posts; others will ask you to do it as well.

Stay happy.
