First let me say I am very sorry about your daughter.
But aml is a fast acting cancer that kills everyone who is not treated, people don't just suddenly recover from it.
It is very common to fail remission for aml after just chemo their are two reasons they don't do a transplant in the first place :
1) their aren't that many donars
2) it's a bloody awful thing to go through.
I had my transplant november 2003, i'm just getting over it, at many points I did not think it was worth it... But I was 29.. Now i'm better i'm very glad I did it.
One day they'll find a cure unfortunately for now we only have the transplant option.
Oh and the other option is to try and be happy and painless until the end.
