Cell phones have totally transformed the way we communicate, work, and, frankly, live. But even though they’ve made so many things so much easier, they’re not always worry-free. Before there were cell phones, no one had a text neck, no one got Blackberry thumb, and no one suffered from nomophobia.

The widespread use of mobile phones has generated public concern over possible health implications related to the devices’ radiofrequency signals and electromagnetic fields.

The controversy centers on whether prolonged cell phone usage increases a person’s risk for brain cancer. On one side of the debate, many scientists assert that the phones’ electromagnetic radiation cannot lead to carcinogenic mutations in the body, supporting their reasoning with basic physics principles. The opposing view cites mix epidemiologic findings; some studies conclude a mild association between cancer and cell phone use, while others show no carcinogenic effect from the devices.


What Science Tells Us

Cell phones give off a form of energy known as radiofrequency (RF) waves. They are at the low-energy end of the electromagnetic spectrum – as opposed to the higher-energy end where X-rays exist – and they emit a type of non-ionizing radiation. In contrast to ionizing radiation, this type does not cause cancer by damaging DNA in cells, but there is still a concern that it could cause biological effects that result in some cancers

 Numerous epidemiologic studies have investigated whether cell phone emissions increase someone’s risk of cancer. The results have been inconclusive. The National Cancer Institute says “A limited number of studies have shown some evidence of statistical association of cell phone use and brain tumor risks, but most studies have found no association.” The federal agency says there are discrepancies because of recall bias, inaccurate reporting, morbidity, and mortality, changing technology and the way people use cell phones.

One thing the researcher do agree on is that there is currently no evidence that non-ionizing radiation increases a person’s cancer risk. Research shows that it does not cause DNA damage that can lead to cancer.


Dr VIMALATHITHAN , oncologist  says about the cell phone uses and cancer risk:  It is, however, clear that lack of available evidence of cancer as regards the use of mobile phone should not be interpreted as proof of absence of cancer risk, so that excessive use of mobile phones should be taken very seriously and with caution to prevent cancer. Furthermore, cell phone companies and regulatory authorities should also ensure that they must abide by the rules and norms that are laid down to govern the energy levels of the cell phone towers.

Dr Vimalathithan: says about  some practical tips you can apply at home: 

  • Use headphones; a hands-free device places more distance between your brain tissue and the phone.
  • Put your phone farther away from you than the nightstand when you sleep.
  • Don’t stick cell phones in pant pockets or inner wearing .
  • Use the phone for shorter conversations or use the speakerphone for longer talks.

“There is no hard evidence to support this, it’s just being careful, like wearing a seatbelt. This is limiting low-frequency radiation exposure. If you don’t need to be exposed to it; don’t be,”
