Difference between Myeloma and Multiple Myeloma

Difference between Myeloma and Multiple Myeloma

Myeloma and multiple myeloma are two different types of cancer that can affect the bone marrow. Myeloma is a blood cancer that starts in the plasma cells, while multiple myeloma is cancer that starts in the white blood cells. Both myeloma and multiple myeloma can cause tumors to form in the bone marrow, which can interfere with the production of blood cells. While there are similarities between these two cancers, there are also some important differences. In this blog post, we will explore those differences and discuss how they impact treatment options.

What is Myeloma?

  • Myeloma is cancer that forms in plasma cells, which are a type of white blood cell. Myeloma causes these cells to multiply abnormally and produce abnormal antibodies.
  • Myeloma is also known as multiple myeloma because it can form in multiple places in the body, including the bone marrow, lymph nodes, and other tissues. Myeloma is a relatively rare cancer, accounting for about 1% of all cancers.
  • Myeloma is more common in older adults, with the average age at diagnosis being 71 years old. Myeloma can be difficult to treat because it is often resistant to chemotherapy and radiation therapy. However, new treatments are emerging that may help to improve the prognosis for people with this disease.

What is Multiple Myeloma?

Multiple myeloma is a form of cancer that develops in plasma cells. Plasma cells are a type of white blood cell that helps to produce antibodies. Multiple myeloma occurs when abnormal plasma cells multiply out of control and form tumors in the bone marrow. The disease can cause bone pain, fatigue, and anemia. Multiple myeloma is treated with chemotherapy, radiation therapy, and targeted therapy. In some cases, a stem cell transplant may be recommended. Multiple myeloma is a serious disease, but with proper treatment, many people are able to live long and healthy lives.

Difference between Myeloma and Multiple Myeloma

  • Myeloma and multiple myeloma are both cancerous diseases that affect the plasma cells in the bone marrow. Myeloma, also called solitary plasmacytoma, is cancer that affects only a single plasma cell. Multiple myeloma, on the other hand, affects multiple plasma cells.
  • Multiple myeloma is more common than myeloma, and it is also more aggressive. Myeloma generally affects older adults, while multiple myeloma can occur at any age. Myeloma is easier to treat than multiple myeloma, and the prognosis for Myeloma is generally better.
  • However, both diseases are serious and can be fatal. Treatment for Myeloma typically includes surgery, radiation therapy, and chemotherapy. Treatment for Multiple Myeloma typically includes chemotherapy and radiation therapy. Bone marrow transplants may also be used to treat Multiple Myeloma. Early diagnosis and treatment are essential for the best possible outcome.


Myeloma and multiple myeloma are both types of blood cancer, but they have some key differences. Myeloma is a single type of cancer, while multiple myeloma is a combination of cancers. Myeloma affects plasma cells in the bone marrow, while multiple myeloma also affects lymphocytes and other white blood cells. The symptoms and treatment for these two cancers can be very different as well. If you or someone you know has been diagnosed with either myeloma or multiple myeloma, it’s important to understand the difference between these two diseases so you can make the best choices about your care.
