No one knows the exact cause of brain tumors. Doctors can seldom explain why one person who developed a brain tumor, and some are not. However, it is clear that brain tumors can not be transmitted. No one can "open" to other diseases.Studies have shown that certain risk factors are more likely than others to brain tumor. A risk factor is anything that increases a person's opportunities for the development of a disease.
The following risks and the development of an increased risk of primary brain tumor-related factors:
Men - In general, brain tumors are more common in men than women. However, the meningioma was more common in women.
Stroke - Brain tumors are more common than in other ethnic groups were white.
Age - Most brain tumors detected in the age of 70. However, the brain tumor is the most common cancer in Japan. (Leukemia is the most common cancer in children) is the most common brain tumor of children older than 8 years old ..
Family history and family who have gliomas may be more prone to the disease - the people.
Exposure to radiation or certain chemicals work:
Radiation - in the development of the risk of brain tumors nuclear industry workers.
Formaldehyde - Mummy processing and pathologists in the development and the work of formaldehyde risk of brain cancer. Scientists have not yet found an other workers exposed to formaldehyde increased risk of brain cancer.
Vinyl chloride - in the plastic manufacturing workers may be exposed to vinyl chloride. This chemical may increase the risk of brain cancer.
Acrylonitrile - People who make textiles and plastics may be acrylonitrile. Exposure may increase the risk of brain cancer.
Scientists are investigating whether mobile phones cause brain tumors. Research shows that mobile phone users have not found an increased risk of brain tumors.
In addition, scientists continue to study whether the head injury is a risk factor for brain tumors.So far, these studies did not find an increased risk of head injuries.
