Central Nervous System
Central nervous system tumours account for some 10% of all tumours in man. The incidence is higher among the white races than among Negroes. The sex ratio is about 1: 1 for most histological types. CNS tumours occur at all ages. There is a peak incidence of glial tumours in childhood; they rank first among solid tumours before puberty. Certain mesenchymal tumours have a familial tendency. Hæmangioblastoma is sometimes associated with other organ lesions (retina, viscera). The role of trauma is debatable.
