Brain tumours in children are a rare but serious type of cancer. They are caused when cells in the brain grow abnormally and form a mass of tissue. These tumours can occur in any area of the brain, but are most often found in the cerebellum, the brain stem, and the cortex.
The exact cause of brain tumours in children is unknown. However, there are a few known risk factors that may increase the likelihood of developing a brain tumour. These include a family history of tumours, having certain genetic syndromes, being exposed to high doses of radiation, and having certain medical conditions.
Having a family member who has had a brain tumour increases a child’s risk of developing one. Certain genetic syndromes, such as neurofibromatosis, can also increase the risk of developing a brain tumour. Exposure to high doses of radiation, such as that used in cancer treatments or imaging tests, can also increase the risk of a tumour developing. Finally, children who have certain medical conditions, such as hydrocephalus or a condition that causes the brain to swell, can be at higher risk for a brain tumour.
There are also some environmental factors that have been linked to an increased risk of brain tumours in children. These include exposure to pesticides, some solvents, and certain viruses. However, further research is needed to determine the exact role these environmental factors may play in the development of brain tumours.
Although the exact causes of brain tumours in children remain unknown, there are a few known risk factors that may increase a child’s risk. It is important to talk to your doctor about any concerns you may have about your child’s risk of developing a brain tumour.
