Does cellphone causes cancer?

Cellphone causes cancer. Urban legend or scientific fact? It is the subject of this post.

Cancer is the modification or destruction of DNA in some body cells. The cellphone radiation has a frequency of 2.4 GHz, the same used by microwave ovens, however with intensity 1000 lower. The cellphone’s radiation is non-ionizing, in other words, don’t have enough energy to rip electrons from atoms and molecules to damage tissues. Radiation a little above ultraviolet is ionizing.

There was a study called “Interphone” to investigate this relation, here is the source:

As a result, researchers teamed up to do a more definitive study, called the “Interphone” study, across 13 countries between 2000 and 2004. The results, published in May 2010 in the peer-reviewed International Journal of Epidemiology, indicated no increased risk of developing two of the most common types of brain tumors, glioma and meningioma, from typical everyday cell phone usage. Study participants who reported spending the most time on their phones showed a slightly increased risk of developing gliomas, but researchers considered this finding inconclusive due to factors such as recall bias.

Another source:

This cohort study, conducted in Denmark, linked billing information from more than 358,000 cell phone subscribers with brain tumor incidence data from the Danish Cancer Registry.

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 (13–15).

Cellphones are used all the time for more than 20 years, there are more cellphones than people in the world. If there had a relation between brain cancer and cellphone use, these types of cases would have increased exponentially in the last years.
