Epidemiology of brain tumors

Primary brain tumor incidence and survival patterns are emerging, assisted by progress in molecular classification. Evidence is accumulating to sugges t that infectious diseases may affect the risk of developing a brain tumor, although data require clarification. Other promising research directions i nclude evaluating the role of diet and allergic conditions in reducing brai n tumor risk. Curr Opin Neurol 13:635-640. (C) 2000 Lippincott Williams & W ilkins.
