It is hard getting a diagnosis of MGUS. It would be good to get more information from your doctor, and hopefully see an oncologist/hematologist for greater knowledge. MGUS is precancerous plasma cells in our bone marrow. Risk of it turning into cancer is about 1%/year, so for most people it never progresses to cancer. MGUS does not have symptoms unless it progresses to multiple myeloma or other active phase. I try to focus on things that I can change, such as diet, activities, and fun.
