My mother has had multiple myeloma for almost 6 years now. She's been through two stem cell transplants and was treated unsuccessfully by chemo for her last relapse. She has IgA, IgG, and in March she found out she has IgM.
She told my sister and I that people in her support group who have been told they have IgM have lived for only an additional 6-8 months.
Her doctors have exhausted all the usual treatments and are now talking about "experimental treatments."
My Mom thinks that she might have a few weeks left.
I can't find anything online about IgM. Does anyone have any information to share?
