There is an increased risk of multiple myeloma in certain occupations. This is due to the occupational exposure to aromatic hydrocarbon solvents having a role in causation of multiple myeloma.

Occupations
In a study to investigate the association between occupational exposure to aromatic hydrocarbon solvents, evidence has shown that these solvents have a role in causation of multiple myeloma. The occurrence of multiple myeloma may occur more in certain occupations. The risk of multiple myeloma occurring is greater in occupations as a firefighter, as a hairdresser, and in agricultural and industrial occupations. The risk in certain occupations is due to the exposure of different chemicals. Repeated exposure to chemicals increases risk of multiple myeloma. The use of pesticides and hazardous chemicals in occupations, like firefighting and agriculture have been seen to cause an increase of risk for multiple myeloma. Other occupations, such as the industrial occupations, are also at increased risk for multiple myeloma. Industrial workers are exposed to chemicals that have aromatic hydrocarbon solvents in them.

Exposure to aromatic hydrocarbon solvents, benzene, toluene, and xylene, can increase risk of multiple myeloma. Increased duration, high intensity of exposure, or repeated exposure was associated with an increased risk of multiple myeloma by up to 63%. The time from exposure to diagnosis was studied, and diagnosis after exposure lagged at least 20 years. When exposure to one chemical was identified, there was usually exposure to another hydrocarbon solvent identified. Multiple myeloma affects more men, older adults, and African Americans. These populations also have higher exposure frequencies than their counterparts.
