@christinaclc ~ Wow! So its you and me! Yes, they did a biopsy on my spine. I was in the hospital for 26 days in April/May of this year. I had massive blood clots & while they were trying to figure out why I was having them, they found the cancer. They did every test, scan, biopsy possible, and still no primary. When I started chemo in June the tumor board & my Oncologist chose to treat as Ovarian cancer and used those meds. The Gyn-Onc concluded its not a Gyno cancer, so here we are again. Interesting though, I also have a rod & 7 screws in my leg. Coincidence? I also hope & pray they know what their doing.
