Hi Amme
Your question is one that I have been thinking about myself having relapsed after my first SCT in 2014 but not yet on further treatment.
I know of several patients who have successfully had a second SCT, and one even a third. Clearly your clinical team is in the best place to advise on your individual circumstances but it seems to be that age and general health, apart from myeloma, are key factors to take into account.
In our area of Merseyside there are agencies which could provide short term support to a family during hopsital treatment, this may be something you could explore in your area – Macmillan might be a good starting point.
Hope this helps.
David
