Scientists say there’s no link between cell phones and brain cancer. Nearly every single adult uses a cell phone in America and some worry the electromagnetic fields produced by mobile phones could cause cancer. But the World Health Organization says, you can breathe a little easier. A team of 11 investigators from 10 countries, including the Australian government’s radiation protection authority, sifted through five-thousand studies from several countries. They say as wireless technology has increased over the past two decades, there is no increase in brain tumors or evidence of a link to cancer. This is true even with people who have used cell phones for over 10 years.
