Multiple myeloma is a relatively uncommon form of blood cancer that affects less than 1% of the U.S. population, according the American Cancer Society.
March is Myeloma Awareness Month. People younger than 45 rarely get the disease, and it occurs more in older men than women. And your risk is doubled if you're African American.
"Multiple myeloma is an incurable blood cancer that produces a lot of proteins that can cause damage to various organs, particularly the bones as well as the kidney," says Dr. Rahma Warsame, a Mayo Clinic hematologist.
