For years, we’ve heard of a possible link between cell phone use and cancer. Now, this week, researchers in Baltimore say the evidence is clear, and children are more at risk, CBS BALTIMORE reports.

The studies link cell phones to a slew of health issues in children. That’s why experts say parents and expecting mothers need to be extra careful.

“The weight of the evidence is clear: cell phones do cause brain cancer,” said Dr. Devras Davis, president, Environmental Health Trust. Dr. Davis says the young brain absorbs twice as much radiation as an adult.

“There’s a correlation between cell phone use in pregnancy and behavioral problems in their children,” said Dr. Hugh Taylor, Yale Schoolof Medicine. “These devices are really stressing and straining our family relationships because the average mom or dad will check their phones 60 to 110 times a day,” said Dr. Catherine Steiner-Adair, clinical psychologist.

Doctors say the infant brain — even while in the womb — is especially vulnerable, reports CBS BALTIMORE.

“Keep the phone away from the abdomen — especially toward the end of pregnancy,” said Dr. Davis. Read more at CBS BALTIMORE.
