Myeloma Causes

The cause of myeloma is unknown. Several factors have been linked to myeloma, including genetic abnormalities, exposures to certain chemicals and other conditions in the workplace (petrochemical industry workers, leather workers, book binders, cosmetologists, shipyard workers, metallurgic industry workers), exposure to very large doses of radiation, certain viral infections, and immune system dysfunction. However, how any of these factors actually causes myeloma is unknown. Some people who develop myeloma have none of these risk factors.
