Causes and risk factors
There are certain risk factors that can increase one's chances of developing a brain tumor. Although most brain tumors are not linked to these factors, some may increase the risk.
Although brain tumors can appear at any age, the risk of this happening increases with age. However, some types of brain tumor are more common in young adults.
Brain tumors are slightly more common in men than in women.
- Genetic conditions
A small number of brain tumors occur in people who have certain genetic (hereditary) disorders such as neurofibromatosis type 1 and 2 or tuberous sclerosis.
People with certain genetic syndromes such as Li-Fraumeni syndrome, von Hippel-Lindau syndrome, Turcot syndrome, or Gorlin syndrome are at a slightly higher risk of developing a brain tumor.
Most brain tumors are not hereditary, that is, they are not caused by a gene that can be passed on to other family members.
- Treatment before radiotherapy
Patients who have had radiotherapy in the area of the head are at a slightly higher risk of developing a brain tumor in the future.
