Why Don’t We Treat MGUS? What MGUS Means for Multiple Myeloma Risk
If MGUS can become multiple myeloma, why don't doctors treat it? IMF Medical Advisor Dr. Joseph Mikhael explains why MGUS is typically not treated and why routine monitoring is important.
Learn what MGUS means, why most people with MGUS do not go on to develop multiple myeloma, and why doctors consider the potential risks of treatment when deciding whether treatment is needed. Dr. Mikhael also explains why regular follow-up is important for identifying changes before MGUS becomes active myeloma.

Dr. Joe Mikhael:
If MGUS will turn into myeloma, why don't we treat MGUS?
Hi everybody. Dr. Joe here from the International Myeloma Foundation, and I'm going to explain why we typically do not treat MGUS in a minute or less.
MGUS is a pre-myeloma condition, monoclonal gammopathy of undetermined significance that actually happens in 5% of people over the age of 40. So it's very, very common. And it just means that there is a small abnormal protein in the blood, but it has not yet grown to a point that it causes damage. We typically don't treat it because most of those patients will not go on to develop multiple myeloma. We want to treat people when the risk is more imminent so that we don't expose people to any risks of treatment that they may not need.
However, it is very important to follow these patients because we know if left unfollowed, the disease can grow and become quite severe. So if someone has MGUS, we want to make sure that they're followed routinely to make sure that we capture it before it becomes active myeloma.
