Among the childhood malignancies, brain tumours are the second most common malignancy, after leukemia. The incidence of these tumours in young people under 20 years of age has been increasing recently. Although survival has improved considerably, the prevention of brain tumours is an important aim, but continues to be a challenge.
So far, little is known about risk factors for brain tumours. Some factors (e.g. exposure to ionizing radiation) and family history of brain cancer are known to increase the risk of developing brain tumours. Other environmental factors (e.g., exposure to chemicals, nutrition during pregnancy or exposure to electromagnetic fields including cellular phone use) may be associated with brain tumours. With respect to the latter, the use of cellular phones and other communication technologies has increased dramatically over the last decade, especially in children and its role in the development of brain cancer in young people has yet to be studied.
One problem in the study of environmental risk factors and brain cancer in young people has been the limited number of children included in previous studies. Although the frequency of brain cancer may have increased in young people over recent decades, it is fortunately still a rare disease. Therefore, international studies are needed to answer such research questions.
An international multi-centre study involving experts from 13 European and non-European countries is being set-up to examine the potential associations between use of communication devices and other environmental factors and isk of brain tumours. The study is partly supported by the European Union.
Over a period of two and a half to three years, starting in 2010, nearly 2000 young people between 10 to 24 years with brain tumours and a similar number of young people without a brain tumour will be invited to participate in the study. A detailed questionnaire will be used covering demographic factors, residential history and questions on risk factors in the environment including the use of cellular phones of young people.
