Brain tumours are of different cell types, the commonest being tumours of glia called gliomas. Many etiological factors of gliomas have been suggested and certain industries have been implicated. Several epidemiological studies have linked electromagnetic fields (EMFs) to gliomas. Health effects of EMFs have been studied, both in humans and in experimental animals, mainly with negative findings. Positive experimental evidence linking EMFs to tumours is the effect of EMFs on melatonin production by the pineal gland. Removal of the pineal gland in rats increases the incidence of tumours. Further epidemiological and experimental evidence is required to elucidate this possible link between EMFs and brain tumours.
脑肿瘤有不同的细胞类型，最常见的是神经胶质细胞肿瘤，即胶质瘤。人们提出了许多胶质瘤的病因，某些行业也受到牵连。几项流行病学研究将电磁场（EMF）与胶质瘤联系起来。人们已经在人类和实验动物身上研究了电磁场对健康的影响，主要结果都是阴性的。将电磁场与肿瘤联系起来的阳性实验证据是电磁场对松果体褪黑素分泌的影响。切除大鼠的松果体会增加肿瘤的发生率。需要进一步的流行病学和实验证据来阐明电磁场与脑肿瘤之间的这种可能联系。
