MOBILE phones do not cause health problems if used for up to ten years, but a long-term cancer risk cannot be ruled out, experts said yesterday.
The impact of mobile-phone use on children is also unknown and must be investigated further, the scientists said.
A six-year research project found no links between mobile-phone use and brain cancer, nor any evidence of brain function being affected by mobile phone signals.
However, cancer symptoms are rarely detectable until at least a decade after a cancer-producing event, the Mobile Telecommunications and Health Research (MTHR) report said.
Professor Lawrie Challis, the chairman of MTHR, said: "We cannot rule out the possibility at this stage that cancer could appear in a few years’ time."
