Radiation from cell phones is associated with higher rates of thyroid cancer among people with genetic variations in specific genes, a new study led by the Yale School of Public Health finds.
The researchers examined over 900 people in Connecticut and found that those with certain single nucleotide polymorphisms (genetic variations commonly referred to as SNPs and pronounced as “snips”) were significantly more likely to develop cancer in their thyroid, a gland in the throat that controls metabolism.
Cell phone users with SNPs in four of the genes studied were more than two times likely to develop cancer. The researchers examined a total of 176 genes and identified 10 SNPs that appear to increase the risk of thyroid cancer among cell phone users.
Published in the journal Environmental Research, the study is believed to be the first to examine the combined influence of genetic susceptibility and cell phone use in relation to thyroid cancer.
“Our study provides evidence that genetic susceptibility influences the relationship between cell phone use and thyroid cancer,” said Yawei Zhang, M.D., Ph.D., a professor in the Department of Environmental Health Sciences at the Yale School of Public Health. “More studies are needed to identify populations who are susceptible to radiofrequency radiation (RFR) and understand exposure to RFR by different using patterns of cell phones.”
