My second cousin had leukemia 10 years ago in her early 20s, got a bone marrow transplant from her brother, went through treatments and has been well for the years since. She's overseas now working for a charitable organization in Nepal.
She had a tough challenge in the treatments, but I'd say she is back to a normal life now, with regular checkups, as this kind of illness requires vigilance.
Best wishes for recovery and return to good health, tallguy. I hope you have a support system around you of family, friends and excellent health professionals.
