Though I am ordinarily no fan of biopsies, it is important for you to find out what you are really dealing with and all you are going to get over the internet is guesses. If it does turn out to be bone marrow cancer, typical mainstream treatment usually includes chemotherapry - often in quite high doess.
As the other poster pointed out, and as your oncologist will likely confirm, mainstream medicine has no cure for bone marrow cancer and can only promise to extend your remaining time. Extending your time with chemo will likely result in some pretty low quality time, given the usual side effects of chemo. I would not opt for chemo but would rather look for natural alternatives which promised to actually eliminate the cancer.
The combination of oleander extract, Budwig flaxseed/cottage cheese, Essiac tea and a very healthy diet and lifestyle has produced good results for many people (and there are some testimonials about such a combo here at CZ). I would also strongly consider a product called Blood Support Tonic, which is a Jon Barron formula modeled closely after famed herbalist Dru Browning's tonic. See:
Browning's Blood Tonic - A Remedy for Cancer and More
The above combo might well help you regardless of what you have, but you really should find oiut for sure what you are dealing with.
