Stating that there is no evidence to blame phones towers, the chief executive of the Cancer Council Australia, Alan Coates, has stated that chance is a more likely explanation for the Melbourne cluster of brain tumours than radiation from mobile phones or any other environmental exposure. .
Professor Coates explained that the cluster of disease happen by chance, he said that there is usually no cause every time they happen though we look for any specific reasons. .
While explaining that there have been extensive surveys but no definitive link between the low levels of electromagnetic energy generated by mobile phones and base station towers and the development of cancer or other diseases, he said that a possible link had not been completely disproved yet. .
He explained that it was reasonable to take the precaution of evacuating the building to reassure workers while testing was undertaken. But he was of the opinion that given the high concentration of mobile-phone antennae throughout Australia and other developed countries, many brain tumour clusters would be expected if radiation were responsible. .
Professor Coates explained that benign brain tumours especially the five of the seven cases detected would typically take many years or even decades to develop to the point of detection. So he felt that the Melbourne workers' condition might have predated their exposure to the phone towers. But he did caution that aggressive, malignant tumours could develop in weeks or months. .
