Does sleeping next to a cell phone cause cancer?

I always wondered this, because I've been using my cellphone as an alarm clock for at least three years if not longer. I heard that sleeping close to an alarm clock itself, or anything electrical is not healthy and should be avoided, so I'm assuming since there's already a scare on the cellphone vs. cancer debate, that there might be some info on how bad it might be sleeping next to one while it's on.

Turns out, there isn't a lot of info on the subject so I'm guessing there's not much to worry about. Even the whole "cellphones will give you cancer" theory is still needing much research and hasn't been proven. Of course I didn't think I'd use the article and now I can't find it, but it said that someone had sued the cellphone companies because his wife had gotten a tumor and he blames cellphones. The charge ended up being dismissed because there wasn't enough evidence. Oh but here's another story, even better...

In the tests, they tested people with cancer and without and noone seemed to get cancer or worsen their cancer by using a cellphone. The article also said that they've been testing rats for a while and the rats got cancer either way since rats are predisposed to getting cancer.

As for sleeping next to your phone...

Many articles have said not to sleep with an electronic device within 3-4 feet of your head. I guess the same goes for a cellphone. Many people in the Yahoo Answers forum say that they've been doing it for years and don't have any issues.

A little experiment at MIT did show however that sleeping next to your cellphone will disrupt your sleep.

Here's some info from a related article by AssociatedContent.com:

"Many phones have 884 MHz wireless signals, which have been linked to affecting one's sleep. In addition those who use their cell phones before sleep have more headaches and are much more tired.

The study further showed that cell phone radiation exposure during the night while reduce one's ability to recuperate from a stressful and difficult day. The study is disturbing that anyone who sleeps remotely close to a cell phone could have many problems during their routine day. The study did not provide the amount of distance the phone has to be by a person while sleeping to have an adverse affect."

So while I found practically nothing about cellphones causing cancer while you sleep (I'm guessing it'll be another 10 or 20 years before they can prove it), I found dozens of articles on cellphones disrupting your sleep. That's enough to atleast put the cellphone across the room at night. The more beauty sleep I get, the better.
