It’s estimated that 3% of people under 70 and 5% of those over 70 (if I remember correctly) have the M Paraprotein. I suspect the incidence is much higher because unless there are symptoms, the M paraprotein is usually discovered because they’re looking for something else. There are three diagnoses (and some subtypes) for those of us with this pesky M paraprotein. MGUS is not cancer. It’s a “precursor” condition, but that’s not even really accurate because many people who have MGUS will not progress to cancer. Smoldering myeloma and multiple myeloma are blood cancers. Not everybody who has MGUS will get smoldering or multiple myeloma, but everybody who has smoldering multiple myeloma or multiple myeloma had MGU first. At least that is my lay person’s understanding. The risk of progression is very small for MGUS patients. 1% to 2% a year.

So if you don’t mind sharing, will there be follow up on your false positive blood test?
