Mobile phones cause cancer?

The World Health Organization said in 2011 that mobile phones cause cancer. There are levels of carcinogens, and the phones have a level 2B carcinogen. Group 2B substances are considered as "possibly carcinogenic". This doesn't mean that it's an emergency call, but it's a possibility (can cause cancer as well as cann't). The degree of threat is too low to consider them a danger or a concern. For example coffee and pickled cucumber also has a level 2B.

There isn't scientific evidence which prove that exposure to electromagnetic radiation from mobile phones are due to cancer. But it's not healthy to accumulate hours with mobile.

I think that we should not stop using mobile phones because there are many things that makes us the same damage. But it doesn't mean that you can abuse of cell phones.
