Mobile phones should carry a health warning like those on cigarette packets, scientists have warned. The authorities must not make the same mistakes over possible links between mobile phones & brain cancer as they did with cigarettes & lung cancer. It took 50 years to get the tobacco industry to acknowledge the risks & 70 years to remove lead from paint & petrol, said Prof. David Carpenter, director of the Institute of Health & Environment at Albany Uni. Dr. Ronald Herberman, director of the Uni of Pittsburgh Cancer Institute – one of the top US Cancer Research Centres – agreed & said: “We must learn from our past to do a better job of interpreting evidence of potential risk.” He added that most of the studies claiming no link between mobile phones & brain tumours are outdated because many defined regular mobile phone use as once a week. He added that most do not include enough long-term users.
