@sanyukta If your mother was diagnosed with smouldering MM, the prognosis is generally wait and see with ~6 month blood testing. Not all SMM progresses to MM. If it is MM, then a PET scan can help with the prognosis and to see if and when to start treatment. Basically, it would be good to get a full discussion with the hematologist regarding the type of SMM or MM (some are low risk, some high), treatment or wait, and testing. There are online support groups with info as well, such as "Rochester MMSS" and pubs on the Internatl MM Foundation (https://www.myeloma.org/).
