Since their invention, cell phones have grown from emergency communication devices to integral parts of our lives. With the dramatic increase in recent decades of mobile technology, some people have worried that all of the radiation increases the risk of developing cancer.
After all, radiation from the Sun, x-rays, and radioactive materials are all capable of damaging cells and causing mutations in DNA that can give rise to cancer. It's understandable that some might be concerned about the radiation from cell phones, because radiation is bad, right?
Well, it's not so simple.
As SciShow explains, radiation is a term to describe the movement of certain types of energy. Not all types of radiation are strong enough to harm our cells and cause mutations. The radiation used for cell phones falls well within the range that is too weak to cause harm. (Incidentally: the light that comes out of a light bulb is technically a kind of radiation.)
Some have anecdotally blamed carrying phones in bras for certain breast cancer diagnoses, but there is no hard evidence linking cell phone to breast cancers of any kind.
If proximity to cell phones did cause cancer, there would be no difference between carrying the device in a bra versus a back pocket. Yes, the cell phone can get warm and heat up the skin, but according to the National Cancer Institute, it doesn't heat it up enough to be a cause for concern.
All that said, there have been some studies conducted that have found a correlation between cell phones and cancer, but there's more to it than meets the eye.
SciShow explains the truth behind those studies here:
