Can Cellphones Really Cause Brain Tumors?

Can cellphones really causes brain tumors? Cellphones are basically two way radios. When you speak, they convert your voice into radio frequency ( RF ) energy. Radio Frequency which travel to the person being called. Right now, it is not clear what occasional exposure to radio frequency over time can do the body, those studies are just getting started. 

Research so far has shown that 22 hours a day exposure to radio frequency radiation heats up the body tissue, which can lead to fatigue, reduced concentration and cataracts. But most people don't spend almost entire day on a cellphone. And evidence indicates there is no increase risk of cancer from cellphones. If you are worried, using a headset or speaker phone will minimize any potential risk, since the antenna area is where most phones emit radiation.
