Hi @djchambers
I am assuming you are in the U.S.? I am in Canada and, last year, I went across the border (Seattle) to have a non-invasive procedure called Histotripsy. At the time they were specializing in eradicating liver tumors (with plans to eventually include more organs). Perhaps you can look into this procedure and see if you are covered. It worked for me eradicating some of my smaller tumors and actually blocked a larger one. It was, however, very costly. They have hospitals in the U.S. (not Canada) that offer it. Another option.
