There are a lot of people who believed the use of cell phones leads to cancer. Well, a new study has indeed found a link between cell phones and cancer.
According to the study conducted by researchers from the National Toxicology Program recently conducted a study, radiation from the devices may cause cancer in male rats.
For the purpose of the study, the research team observed examined 30,000 rats and mice that were exposed to radiation nine hours a day for two years. The exposures began before birth and continued until they were about 2 years old.
After analyzing the results, it was found that around two to three percent of the male rats, which were exposed to radiofrequency radiation like that used on 2G and 3G cellphones made in the 1990s, developed malignant glioma, a deadly brain cancer.
Around five to seven percent of the rats, which were exposed to the highest level of radiation, developed heart tumors. However, the researchers did not find any apparent association between radiation and tumors among the female rats.
“We believe that the link between radio frequency radiation and tumors in male rats is real, and the external experts agreed,” the study coauthor John Bucher said in an official statement.
Notably, it was also found that the risk of lower body weights among newborn rats and their moms increased when exposed to high levels of the radiation during pregnancy and lactation.
Unfortunately, the study result does not indicate anything about any possible cancer risk for humans. The scientists explained the radiation levels and durations that the rats were exposed to were far greater than what humans typically encounter.
“The exposures used in the studies cannot be compared directly to the exposure that humans experience when using a cell phone,” Bucher said.
