• Risk Factors for Brain Tumors

    A risk factor is something that increases your chances of getting a disease or condition.
    It is possible to develop brain tumors with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing brain tumors. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
    There are few known risk factors for primary brain tumors because so little is known about what causes them. They are the second most common form of cancer in children and adolescents (generally under 15 years old). Increasing age is a risk factor for primary and secondary brain tumors in adults.
    Risk factors are also dependent on the specific type of cancer. For example: meningioma, the most common primary brain tumor in adults, is more frequently found in women than in men. It also affects more African-Americans than Caucasians.

    Primary Brain Tumors

    Environmental or Occupational Exposures
    Radiation exposure produces the greatest risk for brain tumors. This most frequently occurs through radiation therapy to the head to treat other cancers. Exposure to radiation can also come from:
    • Imaging tests, such as x-rays or CT scans
    • Occupations, such as oil refining or rubber manufacturing
    Genetics and Family History
    Several uncommon hereditary disorders can increase the risk of brain tumors:
    • Von Hippel-Lindau syndrome
    • Li-Fraumeni syndrome
    • Werner's syndrome
    • Von Recklinghausen's disease
    • Tuberous sclerosis
    • Turcot syndrome
    Having a first-degree relative increases the risk of developing meningioma.

    Secondary Brain Tumors

    Secondary brain tumors come from other cancer sites in the body. Cancers that spread to the brain include:
    Cancer cell development and growth are influenced by a combination of genetic and lifestyle factors. Managing modifiable risk factors, such as not smoking, can help you reduce your overall risk of cancer.
