@somde Smoldering multiple myeloma [SMM] is the second phase of protein anomalies in our blood plasma. MGUS [monoclonal gammopathy of unspecified significance] is the first phase, meaning there is a presence of M-proteins.

From MD Anderson Cancer Center is an article explaining SMM, meaning it can lie dormant, or increase in intensity, like a fire. I guess that is how/why it was named like that! https://www.mdanderson.org/cancerwise/6-facts-about-smoldering-myeloma.h00-159538956.html#:~:text=These%20abnormal%20cells%20can%20turn,to%20get%20worse%20over%20time.

Good question, and definitely something for a trivia game! In this season of wildfires in my area, we don't want to see smoldering anything.
