People who have a risk factor for developing a brain tumor won’t necessarily develop one.
Likewise, many people who develop brain tumors have no known risk factors for the disease.
Nobody deserves a brain tumor, no matter what habits or practices they have.

Radiation Exposure
Exposure to radiation.
HIV/AIDS
People living with HIV/AIDS have roughly double the risk of developing a brain tumor.
Weight
People who are overweight or obese have an increased risk of brain tumors.
Occupational and Household Exposures
Many people are exposed tocarcinogens(cancer-causing substances) at the workplace.
Air pollution and living near landfills are possibly associated with an increased risk.
It’s thought that 5 percent to 10 percent of brain tumors are “hereditary” in nature.
