I saw my consultant again today. She is pleased with me, says not to worry about my recent run of colds "there's just a lot of nasty things circulating, and your bloodwork is completely normal" and is giving me six months this time before seeing her again. She reminded me as always that I can always call the department if I am worried. I told them that I still remember very clearly what it was like getting ill in the first place, and I certainly will get in touch if I think it is happening again. After all, my confidence in my knowledge of my own body has been borne out, if not in the happiest of ways!
Bone marrow samples will continue at 3-monthly intervals until three years after "end-of-therapy". We are now at 11 months after end-of-therapy, so nearly 1/3 of the way there. I asked if I was right to assume that they would call me if there was anything to be concerned about in the bone marrow samples, rather than waiting for my next appointment, and she confirmed that this is the case.
