High RF Exposure Causes Tumors in Male Rats, National Toxicology Program Finds
High exposure to RF radiation (RFR) caused tumors in tissues surrounding nerves in hearts of male rats, the federal National Toxicology Program said, reporting on results of study released Friday. NTP said the incidence of the tumors -- malignant schwannomas…

-- increased in male rats as they were exposed to increasing levels of RFR beyond the allowable cellphone emission levels. They noted an “unusual pattern of cardiomyopathy, or damage to heart tissue, in exposed male and female rats,” said a news release. The amount and duration of exposure were much higher than people experience with even the highest level of cellphone use, said John Bucher, NTP senior scientist. "Tumors we saw in these studies are similar to tumors previously reported in some studies of frequent cellphone users." Scientific evidence continues to show no adverse health effects from cellphone use, a CTIA spokesman said: "The scientific community will consider the NTP draft reports in the context of the many other scientific studies conducted over several decades.” Jeffrey Shuren, director of the FDA Center for Devices and Radiological Health, also said cellphones are safe. “All of this research provides a more complete picture regarding radiofrequency energy exposure that has informed the FDA’s assessment of this important public health issue, and given us the confidence that the current safety limits for cell phone radiation remain acceptable for protecting the public health,” Shuren said.
