Is multiple myeloma classified as a type of cancer?

Multiple myeloma is a type of blood cancer that develops in plasma cells, a type of white blood cell found in the bone marrow. These cancerous plasma cells multiply abnormally, crowding out healthy blood cells and producing faulty antibodies that can damage bones, kidneys, and the immune system.

If you're experiencing symptoms like persistent bone pain, unexplained fatigue, frequent infections, or unusual bruising, it's important not to guess or delay. Understanding your symptoms early can make a meaningful difference in outcomes. Take a free, instant, online symptom check to gain clarity on what your body may be telling you and to help guide your next steps with confidence.

Explanation

Multiple myeloma is a cancer that starts in the bone marrow, where blood cells are made. It specifically affects a type of white blood cell called plasma cells. These cells are part of the immune system and help fight infections by making antibodies. In multiple myeloma, these plasma cells grow out of control and form tumors in the bone marrow.

Key Points:

  • Location: The disease occurs in the bone marrow, which is the soft tissue inside bones where blood cells are made.
  • Affected Cells: It primarily affects plasma cells, a type of white blood cell that makes antibodies to fight infections.
  • Symptoms: As the cancerous cells grow, they can cause bone pain, fatigue, and frequent infections because they crowd out healthy cells. If you're experiencing any of these symptoms, consider using a symptom checker to better understand what might be happening with your health.

Understanding Multiple Myeloma:

  1. Cancerous Growth: The abnormal plasma cells multiply and create tumors, which can lead to weakening of the bones and other health issues.
  2. Impact on Blood Cells: This overgrowth can interfere with the production of normal blood cells, leading to symptoms like anemia and increased risk of infections.

By understanding that multiple myeloma is a cancer of the plasma cells, we can appreciate why it's important to monitor and treat this condition carefully.
