The preliminary finding of the 25 million dollar peer-reviewed study by the National Toxicology Program (NTP), overseen by the National Institutes of Health. found that cellphone communications frequencies at 900 megahertz increased cancer rates in male rats. Although the official report will not be released until 2017, the data concurs with the 2011 World Health Organization finding that cellphone radiation was a group 2B possible carcinogen. This study showed that the telecommunication industry’s claim “there is no risk” hold no water and is similar to the initial tobacco industry’s claim that “smoking did not cause cancer.” Although the harmful effects are probably small, they are a risk factor!
We are the first generation that is covertly and chronically exposed to radio frequency radiatio (RFR). The long term effects are still partially unknown. Who knows what the future effects will be for children whose brains and bodies are still developing while being exposed the cellphone/tablet radio frequency radiation for hours a day. Remember,the RFR is similar to the radar beam–albeit at a lower intensity–used to cook your food in your microwave oven.
I strongly recommend to adapt the precautionary principle and assume that cellphones could be harmful. Thus, keep cellphones and tablets away from your body. Put them in your purse, attaché case, or backpack. Use speaker phone or blue tooth earphones and microphone to talk. When not in use, put it on airplane mode to reduce long term exposure to RFR.

National Toxicology Program Finds Cell Phone Radiation Causes Cancer
SPIN vs FACT: National Toxicology Program report on cancer risk from cellphone radiation
The National Toxicology Program (NTP) of the National Institutes of Health reported partial findings from their $25 million study of the cancer risk from cellphone radiofrequency radiation (RFR). Controlled studies of rats showed that RFR caused two types of tumors, glioma and schwannoma. The results “…could have broad implications for public health.”
A factsheet on the NTP study that summarizes some biased statements, or “Spin,” about the study that tend to create doubt about data quality and implications, as well as “Facts” from decades of previous research is available at http://bit.ly/NTPspinfacts.
According to the NTP report:
“Given the widespread global usage of mobile communications among users of all ages, even a very small increase in the incidence of disease resulting from exposure to RFR [radiofrequency radiation] could have broad implications for public health.”
Overall, thirty of 540 (5.5%), or one in 18 male rats exposed to cell phone radiation developed cancer. In addition,16 pre-cancerous hyperplasias were diagnosed. Thus, 46 of 540, or one in 12 male rats exposed to cell phone radiation developed cancer or a pre-cancerous lesion as compared to none of the 90 unexposed male rats. The two types of cancer examined in the exposed rats were glioma and schwannoma. Both types have been found in human studies of cell phone use.
In the group exposed to the lowest intensity of cell phone radiation (1.5 watts/kilogram or W/kg), 12 of 180, or one in 15 male rats developed cancer or a pre-cancerous lesion.
This latter finding has policy implications for the FCC’s current cell phone regulations which allow cell phones to emit up to 1.6 W/kg at the head or near the body (partial body Specific Absorption Rate or SAR).
The NTP study is likely a “game-changer” as it proves that non-ionizing, radiofrequency radiation can cause cancer without heating tissue.
The results of the study reinforce the need for more stringent regulation of radiofrequency radiation and better disclosure of the health risks associated with wireless technologies — two demands made by the International EMF Scientist Appeal — a petition signed by 220 scientists who have published research on the effects of electromagnetic radiation.
Along with other recently published studies on the biologic and health effects of cell phone radiation, the International Agency for Research on Cancer of the World Health Organization should now have sufficient data to reclassify radiofrequency radiation from “possibly carcingogenic” to “probably carcinogenic in humans.”
The risk of cancer increased with the intensity of the cell phone radiation whereas no cancer was found in the sham controls—rats kept in the same apparatus but without any exposure to cell phone radiation.
In contrast to the male rats, the incidence of cancer in female rats among those exposed to cell phone radiation was not statistically significant. Overall, sixteen of 540 (3.0%), or one in 33 female rats exposed to cell phone radiation developed cancer or a pre-cancerous lesion as compared to none of the 90 unexposed females. The NTP has no explanation for the sex difference. The researchers pointed out that none of the human epidemiology studies has analysed the data by sex.
The researchers believe that the cancers found in this experimental study were caused by the exposure to cell phone radiation as none of the control animals developed cancer. The researchers controlled the temperature of the animals to prevent heating effects so the cancers were caused by a non-thermal mechanism.
One of two types of second-generation (2G) cell phone technology, GSM and CDMA, were employed in this study. The frequency of the signals was 900 MHz. The rats were exposed to cell phone radiation every 10 minutes followed by a 10-minute break for 18 hours, resulting in nine hours a day of exposure over a two-year period. Both forms of cell phone radiation were found to increase cancer risk in the male rats.
For each type of cell phone radiation, the study employed four groups of 90 rats — a sham control group that was not exposed to radiation, and three exposed groups. The lowest exposure group had a SAR of 1.5 W/kg which is within the FCC’s legal limit for partial body SAR exposure (e.g., at the head) from cell phones. The other exposure groups had SARs of 3 and 6 W/kg.
Glioma is a common type of brain cancer in humans. It affects about 25,000 people per year in the U.S. and is the most common cause of cancer death in adults 15-39 years of age. Several major studies have found increased risk of glioma in humans associated with long-term, heavy cell phone use.
In humans, schwannoma is a nonmalignant tumor that grows in Schwann cells that cover a nerve which connects to the brain. Numerous studies have found an increased risk of this rare tumor in heavy cell phone users. In the rat study, malignant schwannoma was found in Schwann cells in the heart.
