Hi Sandra
My husband was diagnosed in 2008 He has had one auto SCT and is now needing a second. Fortunately when he was harvested he managed to produce enough stem cells for 2 autos.
One of the first questions he was asked when first diagnosed was how many siblings he had. Answer none. We had no idea at the time why the question was asked but I believe now that an allo is considered if not enough stem cells can be harvested from the person with mm.
I am a long way off of knowing didly squat about procedures but it seems that allos are carried out more often in the USA than here.
I am sure that someone else on here will be able to give you further information
Kind regards Gill
