There's no way to predict who can and cannot get a brain tumour. However, there are certain risk factors to consider.
According to Mayo Clinic, exposure to radiation can make one prone to a tumour in the brain. "People who have been exposed to a type of radiation called ionizing radiation have an increased risk of brain tumor," experts from the health body explain.
Another reason could be a family history of brain tumours i.e. if one of the members of the family have had a brain tumor.
