I was diagnosed with IgA Kappa MGUS 8 years ago (I'm 70) and my numbers ramp up a bit with every 6 months bloodwork. My kappa is about 300 and kappa/lambda is 28; the BMB I had a few months ago had 15% plasma cells. Ten percent is generally the boundary for SMM but my oncologist says still MGUS due to absence of bone lesions or other damage; he says kappa will need to be in the thousand(s) to be SMM. He is kind of perky (I think of him as Dr. Ken Doll). I take more than 3 gm/day of bioavailable curcumin (Qunol), and my kappa curve has flattened a bit. Don't know if curcumin helps, but I'm fine being a lab rat. Every day I get in some aerobic and resistance exercise, try to escape into books and other interests, get enough sleep, and destress about things I have little or no control over (and screaming into pillows sometimes helps).
