Multiple myeloma is a rare cancer of the bone marrow. It results from the abnormal growth of plasma cells in the bone marrow. Plasma cells normally produce antibodies. As these abnormal or malignant plasma cells multiply, they produce large quantities of abnormal antibodies. These abnormal antibodies collect in the blood and urine. As the plasma cell tumor grows, it also destroys the bone around it. These events lead to bone pain, kidney damage, and a weak immune system.
Risk factors that increase your chance of getting multiple myeloma include:
- Age: 50 or older
- Race: black
Symptoms of early stage multiple myeloma include:
- Persistent bone pain, often severe. It is most common in the back but also in the limbs or ribs.
When the disease progresses, symptoms may include:
- Broken bones
- Repeat infections
- Nausea and vomiting
- Difficulty urinating
- Abnormal bleeding
- Visual problems
Your doctor may need pictures of your bones. This can be done with:
- MRI scan
- CT scan
- Positron emission tomography/computed tomography scan (PET/CT scan)
Your doctor may order tests of your body fluids and tissues. This can be done with:
- Blood tests
- Urine tests
- Bone marrow aspiration or biopsy
- Immunomodulating agents
- Proteasome inhibitor
- Biologic therapies
- Radiation therapy
- Peripheral stem cell transplant
There are no guidelines to prevent multiple myeloma. The cause is not known.
