With more than 7 billion cellphones in use around the world these days, the question that lingers in our heads is how harmful are the radiofrequency emissions to our health.
So-called observational studies, which have looked at large populations in Europe, the United States and New Zealand have not established a definitive link between cellphones and brain cancer.
The studies have relied on survey data, which is weak science, asking people to remember back to how often they used cellphones.
Keep in mind the amount of brain cancer in the world hasn’t increased despite the dramatic increase in cellphone use. And today’s cellphones and smartphones emit much less radiation than those a decade ago, when most of these studies were conducted, Fox News reported.
