As cell phones become an appendage of people’s head, our life almost cannot go on normally without a cell phone. Cell phones, either iPhone from Apple or Hiphone online, are all available to us easily. Along with the rapid development of mobile products, the discussion on cell phones and cancer risk is increasingly fierce. Do cell phones really cause cancer-or not?

In the summer of 2008, Ronald Herberman, director of the University of Pittsburgh Cancer Institute, sent a memo to his staff, warning them to limit their cell phone use and to use hands-free sets in the wake of “growing evidence that we should reduce exposure” to cell phone radiation. A growing band of scientists are also suggesting that a warning for consumers should be raised despite the fact that numerous studies find no connection between cell phones and cancer.

However, opponents hold that there is no epidemiological evidence of a causal connection between the two, and physics shows that it is virtually impossible for cell phones to cause cancer. The effect of cell phone radiation on body appears to be insufficient to cause genetic damage. Electromagnetic radiation in the form of infrared light, microwaves, television and radio signals, and AC power is too weak to harm us, so we don’t worry about radios, televisions, microwave ovens and power outlets causing cancer. Moreover, this kind of precautionary measure will raise unnecessary public alarm and personal anxiety.

On the contrary, supports hold that long term and frequent use of cell phones which receive and emit radio frequency may be associated with an increased risk of brain tumors. Recent research also suggests that although short-term exposure is harmless, long-term cell phone use may be a different story. Therefore, cell phone users should follow the old adage “better to be safe than sorry”.

All in all, no matter the problem is a fact or a fiction, we should keep an eye on it. Some protective measures such as investing in protective cases online or other accessories online for protection or anti-radiation are practical. Before empirical evidence comes out as a decisive arbiter in assessing the cancer risk, the word “cancer” deserves particular emphasis.
