Hi, my husband has just been diagnosed with CML - chronic phase. We were told on the day of diagnosis(1st March) that he would be starting on Imatinib and given a booklet about CML. Today had a phone call to say he’s got to go to hospital on Thursday for ECG and other heart tests, then have a bone marrow biopsy straight after and they’re changing his medication to a more aggressive Tki starting the same day. This all seems so sudden. We had just got our head around things and now it all seems to have changed. My husband is very worried and is thinking that it’s worse than they originally said. I’m trying to stay positive for him so can’t let him know how worried I am. Is this normal procedure!
