At 76 I had a SCT. I had to pass a number of physical tests first. I would recommend getting a second opinion regarding a SCT.

As we age our stem cells become less numerous, less healthy, and less efficient. As a result, the age cap has been determined to be around 72 years, though that can vary. In addition, our ability to withstand the harvesting procedure and the high dose chemotherapy prior to the SCT that is very hard on your entire body. Side effects, including the potential for death, are at a much higher rate with age. It's not the actual SCT that's the problem - it's the procedures to harvest enough healthy stem cells and the pre SCT chemotherapy that are the problem.

Had my SCT 3 years ago at age 76. I needed to pass a number of physical tests to make sure I could handle it. Check with Medicare again, pretty sure they will cover it.
Also you'll find grants are available to help cover the cost.
You might want to get a second opinion regarding whether you would be a good candidate for a SCT.

Greetings from Alaska when I was diagnosed, I was in kidney failure, from IGg lambda light chains. I have chronic CKD but I was given my SCT, which has helped immensely. I will say a pray for you in hopes that a second opinion, will lead you to having an SCT. God bless you.

A SCT is a Stem Cell Transplant where they harvest your stem cells and give you a heavy dose of chemotherapy too kill your immune system then put the healthy stem cells back into your bloodstream too begin fighting the cancer.
