Causes of Brain Tumors

No one knows the exact cause of brain tumors but it is clear that brain tumors are not contagious. Research have shown that certain risk factors are more likely than others to develop a brain tumor. A risk factor is anything that increases the chances of someone developing a disease. Some risk factors that increases the chance of developing a brain tumor are: being male because brain tumors are more common in males, age because people who are older have a greater chance of having a brain tumor, family history because if a family member in the past had gliomas then they're more likely to develop the disease.
