My mother in law is suffering from metastatic brain cancer. she has had Non Hodgkin's lymphoma in the past, and it has now metastatised to the brain, it is B cell type, I want to know if it is curable, she has had surgery, 10 brain radiations and 3 chemotherapies, total 8 chemotherapies have been suggested by doctor, she is being given Mabthera for chemotherapy. I want you to pls guide me through this as people have been saying that its not curable and she will not live for more than 6 months even with the treatment,
