According to AFP, the potential link between mobile telephones and brain cancer could be similar to the link between lung cancer and smoking -- something tobacco companies took 50 years to recognize, according to US scientists' warning. Scientists are currently split on the level of danger the biological effects of the magnetic field emitted by cellular telephones poses to humans.

He added that, like the messages that warn of health risks on cigarette packs, cell phones "need a precautionary message." Carpenter described the situation as "a critical public health issue," and called on the US government to support further research and for the Federal Communications Commission (FCC), in charge of monitoring the use of the radio spectrum, "to review their standards." Also testifying was Julius Knapp, who heads the FCC office of engineering and technology -- responsible for setting limits for human exposure to radio frequency (RF) energy from electronic devices like telephones that they approve, to prevent it from heating up live tissue. "It is important to understand that we rely on guidance from US health, safety and environmental agencies in setting those limits," Knapp said. He added: "The FCC staff is not sufficiently qualified to speak with authority to the science of health effects of RF absorption in the body."
