Well perhaps, and I hope not but, have you taken account that human error has had anything to do with why your tumor measurements would have, on its own changed in the direction that is for the good. But of course I am not a DR. Maybe you should ask your dr. what he may think. If your tumor did shrink in size and continued to until it was gone that would fall under the signpost just ahead....this is the twilight zone.
