The controversy isn't new: Can your cell phone give you brain cancer? But this week Congress is asking doctors around the nation to explain their findings.
Dr. David Carpenter, the director of the Institute of Health and Environment at the University of Albany, says cell phones are more likely to cause brain cancer in those under the age of 20:
"Because the skull is so thin and the head is relatively small, the radiation penetrates almost through the head," Carpenter said on Good Morning America.
Other scientists, however, are not so convinced. Most studies have found that there was no association between cell phones and cancer, a stance shared by the Food and Drug Administration and the American Cancer Society.
QUESTION: Do stories like these make you leary to use your cell phone?
