Factors that may increase your risk of multiple myeloma include:

  • Increasing age. Your risk of multiple myeloma increases as you age, with most people diagnosed in their mid-60s.
  • Male sex. Men are more likely to develop the disease than are women.
  • Black race. Blacks are about twice as likely to develop multiple myeloma as are whites.
  • History of a monoclonal gammopathy of undetermined significance (MGUS). Every year 1 percent of the people with MGUS in the United States develop multiple myeloma.
