Like if you have sickle cell or blood cancer or things can you not just like use a dialysis machine to take out your sick blood and do new clean blood?

My BIL had a donor bone marrow transplant from his son. He went from probably having weeks to live to having survived well and is passed his 3rd anniversary.

Random crazy side effect. Some of those stem cells went rogue and ended up becoming hair cells. After years of bald he’s got a nice crop of hair that is the same colour and wave as his son’s hair, not a bit like his original mop.
