I was diagnosed in 2017, SCT in 2018 all the while having secretory myeloma. In May of 2022, I had a bone marrow biopsy which was normal. In June I had my first CT Pet and it revealed active cancer in one of my ribs. My doctor informed me that my myeloma has become non secretory. Recently I have had a clean CT-Pet and normal light chains; however, I'm concerned about this new status. Have any of you gone from Secretory to Non and do we know is it possible to go the other way?
