Smartphones Causing Cancer ?

In this age of information and technology, it’s almost impossible to imagine your life without smartphones and other digital devices. But, are we using smartphones at the cost of our health? Let’s find out.

Electromagnetic Spectrum

Electromagnetic spectrum is basically a range of electromagnetic waves having different frequencies which are found in nature. The number of waves passing through a point in one second is known as the frequency of the electromagnetic wave. The higher the frequency of the wave, the higher will be it’s energy and it will be more likely to cause damage to human body.

A small chunk of the electromagnetic spectrum having wavelength between 400nm to 700nm is the only part which can be seen by the human eye. That’s why it’s known as visible light. Now let’s talk something about smartphones.

Radiation Emitted by Smartphones

Smartphones communicate with the cell tower through RF radiation. RF radiation is also known as ‘Radiofrequency’ radiation. It’s frequency ranges from 30 KHz TO 300 GHz. It is a combination of Radiowaves and Microwaves. It is basically a non-ionizing radiation. Wait, but what’s non-ionizing radiation and how’s that different from the rest of the electromagnetic spectrum?

Non-ionizing radiation comprises a range of electromagnetic waves which are not capable of separating electrons from the atom. In simple terms, they cannot induce any change in an atom as they have very low energy. Radiowaves, Microwaves, Infrared and Visible Light are types of non-ionizing radiation.

On the other hand, ionizing radiation comprises a range of electromagnetic waves which are capable of ripping apart electrons from their respective atoms. They are very high energy waves. Ultraviolet, X-Rays and Gamma Rays are types of ionizing radiation.

Smartphones emit non-ionizing radiation, which means that they are not harmful to human body. Right?

Well, there’s still not enough evidence to arrive at a definitive answer. Why? Let’s see.

What studies have shown?


An analysis of data from 13 countries participating in the Interphone study reported a statistically significant association between intracranial distribution of tumors within the brain and self-reported location of the phone. However, the authors of this study noted that it is not possible to draw firm conclusions about cause and effect based on their findings.


No association was observed between cell phone use and the incidence of glioma, meningioma, or acoustic neuroma, even among people who had been cell phone subscribers for 13 or more years.

What’s the conclusion?

The Federal Communications Commission (FCC) states that currently no scientific evidence establishes a definite link between wireless device use and cancer or other illnesses.

The mystery continues as there is not enough evidence to arrive at a conclusion for now. Numerous studies are done but they are very much inconsistent and fail to give enough evidence. Intensive research is needed in this area.

For now, you can rest in your couch and enjoy binge-watching your favourite web series on your smartphone. Signing off.
