Exposure to toxic air may raise risk of common brain tumour, says study

Air pollution may not only affect your heart and lungs but can also raise the possibility of developing meningioma — a typically noncancerous brain tumour — according to a study.

This common type of brain tumour forms in the lining of the brain and spinal cord. The findings, published in the journal Neurology, do not prove that air pollution causes meningioma; they only show a link between the two.

The study analysed several air pollutants, including those commonly linked to traffic — such as nitrogen dioxide and ultrafine particles — which are especially concentrated in urban environments.
