What causes multiple myeloma?
The cause of multiple myeloma is currently unknown. This cancer usually occurs in people older than 60 years of age. It is slightly more common in men than in women. It can often run in families. Multiple myeloma is also more common in blacks than in whites. Some studies suggest that workers in agriculture or petroleum-based industries may be at greater risk due to exposure to chemicals.
