I'm so sorry for you. Can't they do chemo and radiation? I have an aggressive fast spreading cancer too...carcinosarcoma but it's endometrial cancer, stage 3C. I've had 4 treatments of chemo and immunotherapy. My CA125 numbers started at 1641 in Feb and went to 744 after 2nd treatment. After 3rd treatment they fell to 179. I'm having labwork today so I'll see how much more they've come down. I think I'd demand treatment. What could it possibly hurt?
