Brain Tumours in Children
Brain tumours are relatively rare in children and account for less than 1% of all cancers in children. However, they are the most common type of solid tumour in children, and the second most common type of cancer overall in children. Brain tumours can affect children of any age, but are most common in those aged 0-14 years.
Primary Brain Tumours
Primary brain tumours are tumours that originate in the brain itself, rather than spreading from another part of the body. They are divided into two main types: benign (non-cancerous) and malignant (cancerous). Benign brain tumours usually grow more slowly and are less aggressive than malignant tumours. Malignant tumours can grow quickly and spread to other parts of the brain or body.
Secondary Brain Tumours
Secondary brain tumours are tumours that have spread from another part of the body, such as the lungs or breasts. Secondary brain tumours are usually more aggressive than primary brain tumours and can grow quickly.
Risk Factors
The exact cause of most brain tumours in children is unknown. However, there are some factors that may increase the risk of developing a brain tumour, such as exposure to certain chemicals, radiation, or genetic conditions.
Symptoms
The symptoms of brain tumours in children vary depending on the type and location of the tumour. Common symptoms include headaches, vomiting, seizures, changes in vision, and behavioural changes. It is important to see a doctor if your child is experiencing any of these symptoms.
Diagnosis and Treatment
Brain tumours in children are usually diagnosed with imaging tests, such as MRI or CT scans. Treatment options depend on the type and location of the tumour, and may include surgery, chemotherapy, and/or radiation therapy.
