What Is Multiple Myeloma?

Myeloma is cancer that starts in plasma cells in your bone marrow, the tissue inside bones where most blood cells are made.

With myeloma, cancerous plasma cells -- called myeloma cells -- grow out of control and can build up in your bone marrow, crowding out your normal cells there. Some people may have no symptoms at first, but the presence of myeloma cells and crowding out of your normal cells can lead to symptoms and complications and affect your immune system.

Learn about the basics of multiple myeloma and talking to your doctor and healthcare team.
