Hello, I was diagnosed in August of 25, with a solitary Plasmacytoma in the L2 vertebrae. Course of action was radiation. It was only 20% effective and doctors want to start doing treat all over. Do a new biopsy, follow up with new blood work and another PET Scan. It feels like we are wasting the next 2-3 months chasing after info they should already have. Anyone have a similar diagnosis with unresponsive radiation treatment and did a follow up treatment that resulted in remission?
