A recent study has been made regarding cell-phone radiation and cancer to inform the public better regarding possible risks. However, the $25 million experiment funded by the government led to confusion and little useful information.
Scientists from the National Toxicology Program exposed a group of rats to high levels of radiation similar to the frequency emitted by cell phones. After the experiment, they compared the results with a control group of rats. Because they could not identify major differences between the ones exposed to the radiation and the ones that were not exposed, scientists regarded it as a breakthrough.
However, they still associated the radiation with a non-malignant growth called schwannoma and a type of brain cancer known as glioma. Despite all of these findings, many experts do not agree with the experiment. Nevertheless, it is true that phone radiation could still have severe consequences in time.
According to Otis Brawley, chief medical officer for the American Cancer Society, all sorts of investigations are made because the public is interested in finding a clear answer regarding cell phone radiation.
It is already known that gamma rays and X-rays lead to cancer because they damage DNA. Plus, UV light is also capable of damaging skin DNA. Lower-energy radiation such as radio waves and microwaves might lead to cancer as well but in some other way.
According to Chris Adami, physics and microbiology professor at Michigan State University, it is possible that cell phone radiation might have some biological effect such as heating protein molecules and fat just like microwave oven does on food. However, it is still not sure if this heating is a real cancer threat.
Furthermore, the previous study was done by toxicologists and not cancer researchers. Nevertheless, Brawley stated that scientists still need to prove if low-energy radiation has any effect on cancer. But if it proves to be true, then the medical field and the phone industry will need to find better ways to tackle cell phone radiation.
Until then, experts advise the public to use the speaker mode or an earpiece if they want to feel safer from cell phone radiation. Plus, holding your phone close to your ear all day long is, of course, not a good idea.
