Yeah it's a spectacular transplant procedure, though it's really not that modern medicine, it has been developed since the 50s! The step where you irradiate or apply chemo to kill off the existing bone marrow had to be done at first because the patients had leukemia so you had to do this anyway. An interesting thing is that if there are still cells left in you, they will be wiped clean by the new transplanted immune system in a so called graft-vs-host response that also sounds like a horror-movie concept :)
