Brain Cancer: causes and prevented of brain cancer

What is the causes of brain cancer ?

As with tumors elsewhere in the body, the exact cause of most brain tumors is unknown,

The following factors have been proposed as possible risk factors for primary brain tumors, but whether these factors actually increase an individual's risk of a brain tumor is not known for sure.

• Radiation to the head 
• An inherited (genetic) risk
• HIV infection 
• Cigarette smoking
• Environmental toxins (for example, chemicals used in oil refineries, embalming chemicals, rubber industry chemicals) 

How is Brain Cancer be Prevented ?

In general, there is no known way to prevent brain cancers. However, early diagnosis and treatment of tumors that tend to metastasize to the brain may reduce the risk of metastatic brain tumors.

• Avoiding or reducing contact with radiation (especially to the head) 
• Avoiding toxic chemicals associated with the oil and rubber industry, embalming chemicals, and other environmental toxins may help prevent brain cancers. 
• Avoiding HIV infection is also suggested. 

The popular press and some web sites suggest that avoiding cell phone use and using a macrobiotic diet will help avoid brain cancer. Currently, there is no good evidence for these claims. In December 2010, a large study of about 59,000 cell phone users, with use times ranging over five to 10 years, claims that no substantial change in brain cancer incidence could be found in these individuals. Investigators suggest that "high usage" of cell phones over long time periods is yet to be investigated. However, for those who want to minimize any radiation dose from cell phones, the reader can consult the web for a list of phones that produce the highest and lowest radiation levels .
