Risk Factors

ON THIS PAGE: You will find out more about what factors increase the chance of this type of cancer. To see other pages in this guide, use the colored boxes on the right side of your screen, or click “Next” at the bottom.

A risk factor is anything that increases a person’s chance of developing cancer. Although risk factors often influence the development of cancer, most do not directly cause cancer. Some people with several risk factors never develop cancer, while others with no known risk factors do. However, knowing your risk factors and talking about them with your doctor may help you make more informed lifestyle and health care choices.

The cause(s) of most salivary gland cancers are unknown, but the following factors may raise a person’s rick of developing salivary gland cancer:

Age. Two out of every three salivary gland cancers are found in people 55 and older, with an average age of 64.

Radiation exposure. Radiation to the head or neck for another medical reason may increase the risk of salivary gland cancer.

Radioactive substance exposure. In some reports, exposure to certain radioactive substances has been linked to an increased risk of salivary gland cancer; in other reports, there is not enough evidence to support this. Talk with your doctor for more information.

Environmental/occupational exposure. Exposure to sawdust and chemicals used in the leather industry, pesticides, and some industrial solvents may increase the risk of a type of salivary gland cancer that occurs in the nose and sinuses.

Other possible risk factors that doctors are investigating but have not proven include exposure to certain metals (nickel alloy dust) or minerals (silica dust), a diet low in vegetables and high in animal fats, and exposure to hair dye or hairspray.

There is no known way to prevent salivary gland cancer.

Research continues to look into what factors cause this type of cancer and what people can do to lower their personal risk. There is no proven way to completely prevent this disease, but there may be steps you can take to lower your cancer risk. Talk with your doctor if you have concerns about your personal risk of developing this type of cancer.
