My Dad was diagnosed with multiple myeloma over a year ago. He received chemo followed by a stem cell transplant in August. The last 6 weeks he has finally began to recover from his transplant & start to live a more normal life. He began to feel confused & disoriented. Today after surgery it was determined that he has several tumors growing around his brain. These tumors are cancerous & life threatening. Myeloma has spread to his brain & I can’t find any information about this. I know it is rare but does anyone have any experience w/ this?
