Hello Starmern and thanks for posting, 

If the doctors are considering treating anyone with a bone marrow or stem cell transplant (the main difference is whether donated blood cells are collected from the bloodstream or bone marrow) they would instigate the search for a suitable donor which would usually include testing some family members. I believe the best chances of a full match are with a sibling. But not everyone is suitable for this sort of treatment and I don't know it is might ever be an option for your mum.

Members of the public can volunteer to be a donor.  This involves getting tested,  a donation would only be required if they matched up with someone. But I don't think this is what you meant. 

Transplants are quite a sophisticated type of treatment. You can read more about them on our website at this link. 

Give us a ring if you want to talk anything over. The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.

Best wishes, 

Julia
