Researchers are now using rodents to find out how exactly more exposure to cell phone radiation affects tumor growth. They exposed the mice and rats to radiation that are equivalent to the radiation that people get from cell phones. They gave the mice high doses of radiation every day for two years. The rats were compared with those who did not receive radiation. It was found that 3% of the rats developed tumor. Heart tumors were found in 7% of the rats. Scientists found that male rats exposed to two types of RF radiation are more likely than unexposed rats to develop a type of brain cancer called glioma. They also had higher chance of developing schwannoma, a rare and malignant heart tumor. By increasing the intensity of radiation, the incidence of cancer in the rats also increased. The highest level of radiation was five to seven times as strong as what humans typically receive while using a mobile phone.
