What Are the Causes of Brain Cancer?
by Jill Richards
Brain cancer can be primary, meaning the tumor began in the brain, or secondary, where it started in another part of the body, like the lung or breast, and then spread to the brain. According to the National Cancer Institute, brain tumors tend to occur in children under 12 and adults over 40. They can be malignant or benign. While scientists have not pinpointed the exact cause of brain cancer, research has shown that there are risk factors that make certain people more vulnerable.
Whites are more likely to be diagnosed with brain cancer than other ethnicities.
Those between the ages of 40 and 70 are more likely to get brain cancer.
Workers in industries such as such as oil refining, rubber manufacturing and drug manufacturing are more often diagnosed with brain tumors. Other studies have shown that those exposed to chemicals or radiation on the job have a higher incidence of brain tumors.
A genetic link may mean brain cancers run in certain families, though this appears to happen in only a small amount of cases.
Though research is currently being conducted, no evidence has been found linking cellular phone use and brain tumors.
