Brain tumours are responsible for approximately 2% of all cancer deaths. Central nervous system tumours comprise the most common group of solid tumours in young patients, accounting for 20% of all paediatric neoplasms. The overall inci- dence of brain tumours is 8–10 per 100 000 popu- lation per year. A study by the United States Department of Health in 1966 showed the inci- dence to be 21 per 100 000 per year at 2 years old and 1 per 100 000 during the teenage years. The incidence increases after the 4th decade of life to reach a maximum of 16 per 100000 per year in the 7th decade. There has been an intense debate con- cerning the increased incidence of brain tumours, especially in the elderly, but this possible increase could be explained due to the advent of CT and MRI leading to better detection of tumours.
