Mayo Clinic's MGUS experts provide comprehensive care for more than 3,500 people with MGUS each year.

  • Teamwork. A specialist in blood diseases (hematologist) will oversee your care. Other specialists — including neurologists, nephrologists and dermatologists — participate in your care as needed.
  • The latest techniques and technology. Mayo Clinic pathologists are skilled in the testing and identification of the M protein and determining the potential risk of progression to cancer.
  • Research advances. Mayo Clinic researchers coined the term "monoclonal gammopathy of undetermined significance (MGUS)" when they identified the condition. These experts are studying MGUS to better understand it and to improve treatment options.
