Thank you Ginger for responding. I was just diagnosed with MGUS so all is pretty new to me. My second round of bloodwork to check on any changes won’t be until Aug. My replacement surgery would be a shoulder that is bone on bone. I just saw the surgeon and he was not concerned with my MGUS, but I had not found this article in the NIH National Library of Medicine that mentions the possibility of an elavated risk of MM when I saw him. I imagine this is a question for my hematologist anyway but I wondered if anyone had any experience with this. Thank you again. Peggy
