What @sift666 didn't mention was that the brain tumour was an acoustic neuroma, one of the two tumours specifically mentioned in the International Journal of Oncology article you quoted. We also have two towers that we presume are cell phones towers close by where we work and live, one maybe 150m away, one more like 100m or less. We turn our WiFi off except when we're using it, but we can see about 10 neighbours listed in the available networks. So this proposed, even worse, system is pretty alarming.
