National Toxicology Program finds cell phone radiation causes cancer

1 in 12 male rats exposed to cell phone radiation developed cancer or a pre-cancerous lesion.

1 in 15 male rats exposed at the lowest power level of cell phone radiation developed cancer or a pre-cancerous lesion.

900 MHz was the frequency.

928 MHz is the frequency for many Smart Meters.

Preliminary Summary (to be updated later today)

Last night the National Toxicology Program (NTP) of the National Institutes of Health issued the first in a series of reports that contains partial findings from their long-awaited, $25 million study of the cancer risk from cell phone radiation. This report summarizes the study of long-term exposure to cell phone radiation on rats. The report on mice will be issued at a later date. According to the 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. No cancers were found in 90 male rats in the unexposed control group. 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. 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, in female rats the incidence of cancer among those exposed to cell phone radiation was not statistically significant.

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 specific absorption rate (SAR) of 1.5 W/kg which is within the FCC’s legal limit for partial body exposure (e.g., at the head). 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.
