My husband is 78, was in very good health and was diagnosed with high risk MM in May 2022. He went through 4 rounds of Chemo and had a stem cell transplant at Mayo Clinic Rochester on Dec. 9th. It was not easy and he did spend 10 days in the hospital. He had a very sore throat and esophagus which made it difficult to eat but had very little nausea. Very few other side effects. His care was exceptional and you do want a good caregiver. He did have some atrial fib. and a few sincopal episodes.
He got home on Dec. 31st. and is feeling great. He had no organ damage but will be consulting a cardiologist for irregular heart beats. He will be starting maintenance chemo in April.
He says it is the hardest thing he has ever done but would go through it again if he had to.
It is a hard decision but if it will prolong your life it is worth it.
Best of luck to you with whatever decision you make.

My mother who was 77 in 2015. Found out she had mm in December. After she fell and broke her back. She stayed in bed at home until I called an ambulance for her in late February. She passed away April 1st. But the reason was because they started her chemotherapy, then gave her a colonoscopy bag, then put her in surgery for a pick line for the chemo. Her body was very weak by then and she contracted staff infection. Which she couldn’t fight off. When doctors tell you what they want to do to your loved one you think they know what they should do but I think sometimes we should consider if they need some time to get stronger after surgery especially if they are on chemotherapy. Just my opinion.

That question is for a good resercher f MM, my wife had the bone marrow transplant and also the Cart t cell and did not work. But in most of the cases work, your DNA establishes the rules
