My wife is a myeloma patient. She was on dialysis for 4 years because of a myeloma induced kidney failure. She got a kidney transplant. She was in deep remission at the time, which was confirmed a year earlier (not 5 years), but she was not cancer free since myeloma is incurable. I did extensive research into the subject. There are people who have received a kidney transplant with a more active myeloma than hers. It has been more than a year, the kidney is working fine, no issues from myeloma. This is a difficult subject. 10-15 years ago myeloma was a complete counter-indication for a kidney transplant. Not anymore, but many doctors do not know this. It will take a lot of convincing (it did from us) or looking for a different specialist.
