So very sorry about your sister's condition. My wife was diagnosed with MM in late 2019. Her situation to me, a novice looked grim since in hindsight we remembered 5 years earlier that she had asymptomatic leg fractures. We thought nothing of it at the time so we missed out on treating her years sooner. We found a comprehensive cancer center (the only one in our state) and began treatment with one of several MM specialists. Did your sister see one or more MM specialists who participated in her diagnosis? I've also been told that a second opinion is also imperative since MM is so complex. What was their assessment based on if you don't mind me asking? Take care and share anything more you care to but maybe another opinion will help. The word hospice is very scary at first. They mentioned it to my wife and I as a choice and explained it wasn't always an end of life choice, so there may be more hope, but without one or more expert opinions I wouldn't stop asking questions. Thinking of you and your sister. Sincerely!
