Sickle cell disease (SCD) is a group of inherited or genetic conditions that affect the red blood cells. Sickle cell anaemia is the name of a specific form of sickle cell disease.
If you have sickle cell disease, this means that your red blood cells have a tendency to lose their shape and become sickle-shaped (like a crescent moon) - instead of the normal disc shape. This means that they can’t transport as much oxygen as normal cells.

A bone marrow or stem cell transplant would only normally be considered if you have severe sickle cell disease.
If you have a brother or sister, your doctors will normally test them first to see if they’re a match and you can have a transplant using their stem cells.
If not, then they may consider an allograft transplant – where your new stem cells are donated from an unrelated donor. Or a haplo-identical transplant, using stem cells from one of your relatives whose tissue type partially matches yours.
