Are Cell Phones Linked to Brain Cancer? National Toxicology Program Releases Results of Multi Year Study

Washington, DC -- (SBWire) -- 02/02/2018 --The National Toxicology Program (NTP) division of the National Institutes of Environmental Health Sciences (NIEHS) is releasing the full results of its multi-year study on mice and rats exposed to cell phone radiation today at noon EST.

The NTP will hold a media telebriefing to answer questions Friday, Feb. 2, 1:00 p.m. EST.

"The NTP tested the hypothesis that cell phone radiation could not cause health effects. This hypothesis has now been disproved because partial results the NTP released last year show cell phone radiation has adverse effects. These same cells that became cancerous in rats are the same cells that are reported to turn into tumors in people in epidemiology studies of cellphone users," remarked Ronald L. Melnick, PhD, Advisor to Environmental Health Trust (EHT) and the senior NIEHS toxicologist who designed the National Toxicology Program (NTP) study.

Melnick pointed out that "the NTP also reported DNA damage in some of the exposed animal groups. For children cancer risks may be greater than that for adults because of greater penetration in the brains of children."

"People could be receiving cell phone radiation exposures into their body that are far higher than the NTP studies. Recent tests on hundreds of phones tested by the French government found that most phones exceeded government allowable levels when they were tested in positions where the phone was touching the body. Some phones had radiation levels that were up to an estimated 9 times the allowable US limits," stated Devra Davis, PhD, MPH, President of EHT referring to the scandal dubbed "Phonegate" after the French government agency refused to release the tests.

"Phones do not belong in pockets, laps or bras," Davis said pointing to the Cleveland Clinics recommendations to keep phones away from the body after their research found sperm was damaged after exposure to cell phone radiation.

"Even if there are no new findings from this report. We have more than enough scientific evidence of harm to make policy changes. This is not just about cancer, peer reviewed research has also found many other effects, including damage to brain development," she said pointing to a Yale study that found mice exposed to cell phone radiation during pregnancy had poorer memory and increased hyperactivity.

"Peer reviewed research has also found damage to brain development," she said pointing to a Yale study that found mice exposed to cell phone radiation during pregnancy had poor memory and increased hyperactivity. "People need to know the health risks posed by cell phone radiation and how they can limit exposure."

"Scientists working for the state of California's Department of Public Health developed guidelines for reducing cell phone radiation that have been suppressed for years. When the cities of San Francisco and Berkeley wanted to have a Right to Know Ordinance for cell phone customers to understand the radiation exposure hazard, the wireless industry sued them to prevent the information from being posted. San Francisco withdrew their ordinance, but Berkeley's rule prevailed in court. The wireless industry is now appealing to the U.S. Supreme Court," stated Davis.

"The evidence indicating wireless is carcinogenic has increased and can no longer be ignored," stated physician epidemiologist Anthony B. Miller, MD, referencing several published studies in addition to the NTP results. Miller is a physician epidemiologist and Senior Scientist to EHT who has been a longtime advisor to the World Health Organization and was Senior Epidemiologist for the International Agency for Research on Cancer.

"The NTP study should have been completed before cell phones came on the market, not decades afterwards. Worldwide over a dozen countries recommend reducing cell phone exposure, especially to children," explains Theodora Scarato, Executive Director of the Environmental Health Trust (EHT). "Consumer Reports and the American Academy of Pediatrics have long issued advice to parents on how to reduce children's exposure. Even more importantly strong protective policy is needed for long lasting and meaningful change. Solutions exist. We need protections in place now to protect our children's future."

Examples of EHT Suggestions for Cell Phones:

Do not carry cell phones in bras or tucked in clothing.

Do not carry cell phones in pants pockets.

Put wireless devices in "airplane mode" with Bluetooth off when not actively using them.

Use speakerphone or hollow cord headphones with cell phones.

Wait until you are in an area of good signal (more bars) to use the cell phone.

Use a corded landline phone whenever possible to minimize cell phone use.

Minimize exposure to wireless devices by choosing wired technology, especially for children.
