Mr. Miller, you talked about tumours that have been found on the side of the head where people hold their cell phones. In some women, breast cancers have been found next to where they kept their phone in their bras. Have any studies been done on that? Have any problems been detected in men who keep their cell phones in their pants pocket? Was there an impact in that regard? Are there testicular cancers or issues with male fertility that have come out in these studies?
