Hi, last year i was diagnosed with acute myeloid leukemia. Chemotherapy didnt work, so the hospital had me undergo a bone marrow/stem cell transplant, which happened in august last year. However 2 months ago, i was told that i needed to have Azacitidine jabs every month for 12 months, each time for 5 days consecutively.

My questions are:
What is the purpose of me having to go through Azacitidine jabs after i have already gone through a stem cell transplant?
What happens if i don’t take the Aza jabs or what happens after i stopped them in a few months? Will i have a relapse and die?
Also, what happens if my donor cells does not wake up? Does this also mean a relapse?
