@diana1958 Welcome to Mayo Clinic Connect! It is almost always a surprise when we are handed an unexpected medical diagnosis. And certainly can be very anxiety-provoking as we come to terms with what we might be facing.

There are several conversations you might find useful to read through, regarding MGUS. Here is one: https://connect.mayoclinic.org/discussion/diagnosed-mgus/
When you go to the Blood Cancers support group, you can type in MGUS in the search bar and then choose a discussion to read.

MGUS rarely advances beyond just that, and the most common treatment is a "watch and wait" approach. It is a condition most commonly found when our medical team is looking for/reviewing something else entirely. Labwork is done routinely to monitor critical numbers. I'm glad your PCP is sending you to see a hematologist/oncologist, but please do not stress about it all. Be gentle on yourself.
