They have been studying the disorder for decades. The focus is on finding risk factors for getting the condition, how these risk factors might affect treatment, and how to prevent MGUS from leading to blood cancers and other conditions. Doctors and scientists with Mayo Clinic Comprehensive Cancer Center are working on improving the diagnosis and treatment of myeloma and other blood disorders.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
