Cell Phones Cause Cancer

Cell Phones Cause Cancer

tech myths busted
Many consumer technologies rely on energy and therefor emit or use some form of radiation. Even radio waves are a form of radiation, and since cell phones use them, there’s been concern that having a source of radiation close to our heads could cause cancer. This has been backed up by an alarming report from the World Health Organization which labeled cell phones a “Class B Carcinogen”.
You’d expect that to be based on some fairly hefty evidence, right? Actually, the WHO report is less damning than it sounds in headlines. Class B simply means that a study has indicated that there might be a link, but the link is too weak to be definitive. Meanwhile, numerous other studies have found no link. This includes a massive Danish study involving 350,000 people that was released in late 2011.
Further evidence against the risk of cancer can be found in what we know of physics. Radiation comes in multiple forms, and humans only need to worry about radiation energetic enough to damage DNA. Ultraviolet rays from the sun, which can cause skin cancer, are over 400,000 times more energetic than those emitted from cell phones. Low energy waves like radio can’t hurt DNA, and that means they can’t cause cancer.

Everything Electronic Causes Cancer

tech myths
This means that what holds true for cell phones should hold true for other wireless devices, as well. The rise of wireless networks has caused distress about what all those waves bouncing through the atmosphere might do to our cells. The answer is simple – nothing.  Sleeping on a bed made of wireless routers would be uncomfortable, but it’s not going cause cancer.
Some users become concerned because of another alarming effect. Heat. As electronics are used, they put out heat, and that heat is absorbed by our bodies. That’s why your thighs are warm after using a laptop.
Computers can be harmful if they’re too hot, but the problem isn’t limited to electronics. Dermatologists have long known that constant exposure to heat can cause scaly, discolored skin which is often permanent. A hot computer can cause this – as can a heating blanket, seat warmer, fireplace or oven.
While skin discoloration and minor burns can be a problem to a handful of people, there’s no evidence that normal, intermediate use of a computer will cause cancer. The lesson from dermatology is simple. If something is hot, don’t hang around it too long.

Conclusion


This is merely a handful of tech myths. There are plenty more out there, ranging from the believable to the utterly outrageous. Have you heard a tech myth that you later found out wasn’t true? Tell us about it in the comments.
