Our lives are saturated with technology. From computers to iPods to cell phones, we're immersed in it and a recurring concern about those phones is making the rounds again.

The phones are everywhere you look.

Meckensie Jensen, "can't live without it, pretty much."

And Kobi Davis tells us, "I talk to my dad all the time. I get to hear what he says. It's really fun for me."

Now a researcher with the University of Pittsburgh Cancer Institute suggests we might want to limit cell phone use.

Dr. Ronald Herberman says, "This potentially could contribute to increased risk for developing brain tumors, particularly the area of brain close to the ear."

Dr. Herberman points to unpublished research that suggests signs of concern, especially in youth, because their brains are still developing.

But Dr. Charles Enke, with the Nebraska Medical Center says, "I think that's irresponsible based on the available information."

Dr. Enke is a radiation oncologist with Medical Center and he says there is not enough evidence to cause a stir.

He says, "I would say the risk of a teenager using a cell phone and driving and getting into a fatal accident dramatically exceeds their risk of death compared to the risk of developing a brain tumor."

If you are concerned about the radiation from your cell phone, Dr. Herberman suggests plugging in an earpiece to distance yourself from the phone itself.

The concern of a possible linke between cell phone use and cancer has been studied several times. Results show there is not a significant link between increased tumors and cell phone use.

The Food and Drug Administration also says they see no safety concerns with using the technology.
