Viewpoint from a patient who was diagnosed with high-risk MGUS (6-8% plasma cells in 2 BMBs, light chains 100:1 lambda:kappa, M-spike, BJ proteins in urine) about 9 months ago, teetering on edge of treat / watch closely): you DO NOT NEED anyone here to "decode" your mother's labs. You need your mother's doctor (preferably hemo/onco) to do so. This is complex stuff. The most people here can do is wish her (and you) well.

@karishmagupta We are not medical professional here. We are fellow patents and caregivers who share our experiences and offer support to others going through the same thing.

Please take to your mother's doctors for them to tell you what the biopsy results indicate. They are your best source for information for your mother's individual case.
