Last January, a team led by Yawei Zhang of the Yale School of Public Health in New Haven published an epidemiological study on the possible link between thyroid cancer and cell phones. Though some “suggestive” associations were seen among long-term users, none was statistically significant. Still, the results “warrant further investigation,” they advised.
Zhang did follow up, and what she found could well change the way people think about cell phone cancer risks.
She discovered that some people have an innate susceptibility to thyroid cancer when exposed to cell phone radiation. These individuals have small variations in their DNA which affect the functioning of seven different genes.
All seven genes regulate DNA repair.
