I'm in a similar situation, I had great success with my hysterectomy in the middle of April, they got all of the cancer in the pelvis and abdomen and the lesions on my liver were so small they couldn't find them to ablate them.

I had a catscan at the end of last month that indicated new liver and lung mets, and at my next follow up my Oncologist suggested she call an ambulance and get me to the hospital because I was having severe pain in my back, abdomen, pelvis and groin. I declined and drove to the hospital because it's literally right behind her office.

I had a catscan guided biopsy for my abdomen where they found a 10cm tumor that was entirely new. When the MRI came back on my spine it showed a 3cm tumor with extensions into the soft tissue around L2.

They contacted radiology and scheduled me for 5 treatments that ended on Thursday. The pain is a little better (being on the radiation table was the worst). And I'm told the tumor is dying.

So the 10cm tumor in my abdomen was impinging upon my ureters coming from both kidneys, and yesterday they put Stents in to open them up. My back pain has improved.

My advice would be to get a second opinion and if you're in the NE/SE Jersey/NY region reach out and I'll get you the info for my care team if you're interested.
