About Multiple Myeloma

Plasma cells live in the bone marrow and make the antibodies that fight infection. In multiple myeloma, one plasma cell turns cancerous and copies itself until the marrow fills with identical myeloma cells. Those cells do 3 kinds of damage. They crowd out the marrow's normal work, so red cells, white cells and platelets fall, which explains the tiredness, infections and bruising. They eat into bone, which causes pain, fractures and a dangerous rise in blood calcium. They also pour out a single useless antibody fragment, called M protein, that thickens the blood and clogs the kidneys. The disease is called multiple myeloma because it usually shows up in many bones at once.

Doctors stage it with 2 blood tests, beta-2-microglobulin and albumin, plus genetic changes in the myeloma cells. Myeloma that has not yet caused symptoms is called smoldering myeloma and is often watched rather than treated. Myeloma that comes back after treatment is called relapsed, and myeloma that keeps growing during treatment is called refractory. Most trials describe their patients using those 2 words and the number of prior treatments.

Myeloma sits at the edge of the definition used for rare diseases in the United States. The National Cancer Institute estimated 202,793 people were living with it in 2023. Death rates have been falling about 3% a year, and the 5-year relative survival is now 63.7%, because the number of treatment options has grown so quickly.

Common Symptoms of Multiple Myeloma

Recognizing the signs of Multiple Myeloma early can lead to faster diagnosis and better outcomes. Symptoms may vary in severity from person to person. If you or a loved one are experiencing any of the following, consider speaking with a specialist.

  • Bone pain, most often in the back or ribs
  • Bones that break easily
  • Frequent infections or a fever with no clear cause
  • Tiredness and shortness of breath from low red blood cells
  • Easy bruising or bleeding
  • Weakness in the arms or legs

Who Multiple Myeloma Affects

Myeloma is a disease of older adults. The median age at diagnosis is 69, and about a third of cases are found between ages 65 and 74. Men are diagnosed more often than women (9.1 versus 6.1 per 100,000 a year), and Black Americans are diagnosed at 2 to 2.5 times the rate of white Americans. A silent precursor stage called MGUS, in which the abnormal protein shows up on a blood test but causes no harm, is a recognized risk factor. Radiation and certain chemical exposures also raise risk.
