There are many factors. I had a friend studying the induced magnetic field and it's effects on tissues (vs frequency etc) long time ago. The conclusion was that there are overall cancer related and other brain related problems. It was her postdoc, and she also had access to the city subway lines for more tests. So from the people I've known doing research and other anegdotal evidence, there is a link. It still perplexes me how most of the studies in the end conclude there is overall no human-related high risk. So maybe cellphones+ other generators are like peanut allergies, to some are fine, to others they are fatal. It's too complex of a subject anyways. ... Edited for minor misspell
