Clear evidence phones give rats cancer – The Wall Street Journal

DUBLIN – Cellphone radiation has been a popular whipping boy on alternative health forums. A range of health problems from infertility to brain tumours have been ascribed to the radiation emitted by cellphones and cellular towers. I remember reading years ago of a case in South Africa where a family living near a cell tower in Johannesburg had reportedly turned blue (this was in YOU magazine, so I took it with a grain of salt). Scientists have been working to determine exactly what, if any, health effects are possible from cellphone radiation exposure. Studies on this type of thing take time – it took decades for scientists to conclusively show that smoking causes cancer, and there are still plenty of conspiracy theorists (usually smokers) who say it isn't so. Nevertheless, we are starting to see results from long-term studies on the subject. In the study reported below, researchers say that have "clear evidence" that cellphone radiation causes tumours on the hearts of male rats. This may not sound like much, but for this type of research, this is a very strong finding. As a mobile phone user, I sincerely hope that cellphones aren't the next cigarettes. – Felicity Duncan.Scientists Find 'Clear Evidence' Cellphone Radiation Can Cause Cancer in Rats.By Sarah Krouse.(The Wall Street Journal) U.S. researchers found "clear evidence" that cellphone radiation exposure can cause cancerous heart tumours in male rats. It is still unclear what the final conclusions of their two-decades-long study of the health impact on rodents mean for humans..___STEADY_PAYWALL___.Scientists at the National Toxicology Program, which carried out the major study, this week published final reports that express more confidence in links between cellphone radiation exposure and some tumours in rats than they did in draft reports earlier this year..Their final reports, for example, concluded that there is "clear evidence" that male rats exposed to high levels of cellphone radiation developed cancerous heart tumours, after initially saying there was just "some evidence"—a less certain classification..They also said there was "some evidence" of brain and adrenal gland tumours in male rats that were exposed to cellphone radiation after characterizing that evidence as "equivocal" earlier this year..The changes were made after scientists in charge of the study accepted the recommendations of a panel of experts that reviewed the findings..In female rats and male and female mice, the link between cancers and exposure to cellphone radiation was less clear, the researchers said. One surprising finding in the study was that exposed male rats lived longer and had a significant reduction in a type of kidney disease..John Bucher, a senior scientist at the NTP, warned on a call that the exposure used on rodents in the study was "not directly comparable to the exposures that humans typically experience when using a cellphone.".The study focused on radio frequency radiation akin to what's used in 2G and 3G cellphones and exposed animals to cellphone radiation at levels higher than what human cellphone users typically experience..Mr Bucher said he personally has "no hesitation at all" in picking up the phone for short calls, but for longer calls he tends to use "earbuds or some other way of increasing the distance between the cellphone and my body.".He said the NTP's role was to conduct the research for regulatory agencies and the public, not to issue warnings to consumers..The U.S. Food and Drug Administration asked the NTP to carry out the study in 1999 because usage of cellphones was widespread and little was known about the impact of cellphone radiation..Mr Bucher said future research will focus on newer generations of wireless technology such as 4G, 5G and Wi-Fi and that researchers had learned ways to accelerate the speed of new studies..Write to Sarah Krouse at sarah.krouse@wsj.com
