Hi Peggy, so sorry to hear of an extra burden to your OH.
If you look on Macmillan cancer website it explains what myeloid leukaemia is and how it is treated. Only chemotherapy is used but there are trials that give intensive chemo so will be worth asking to go on one of them if you are deemed suitable.
Three years ago my brother was diagnosed and given six months but went on trials, had chemo every day for one month and is now in remission he had a hard time but has battled through it and lives a normal life now.
I hope you find the information that you need from your oncologist and you can make whatever decision you need to make.
Life seems different upside down, take another viewpoint
