Research doubts link between cell phones, cancer

Back in May, the World Health Organization (WHO) issued the controversial results of a study that linked frequent cell phone usage to certain types of brain tumors. Now a scientific journal, Environmental Health Perspectives (EHP), has published an overview of similar studies that casts doubt on any links between cell phones and cancer.

The journal notes that the WHO report was attempting to classify what kind of cancer risk might exist, not the actual probability of developing cancer. EHP had issues with the reliability of the WHO study, which asked 13,000 phone owners to remember cell phone usage from many years ago. The EHP authors mentioned that a number of other studies have not seen a link between cell phones and cancer.

The importance of the EHP report lies in the fact that the journal has no connection at all with the cell phone industry, therefore reducing concerns of bias.

we must take precautions when ever we use cell phones, that's all we can do now.. we can not ban the cell phones because they are our biggest need, so better take precautions.

Didn't a group of scientists from the IARC come out with a list of execs that were previously long term employees of Motorola? The government is obviously putting pressure on the IARC and other research groups. The study may seem like there's a weak correlation between cell phone use and brain tumors, and you could easily use the "correlation doesn't equal causation argument," but after all the reports I've read about pressure from lobbyists, scientists getting fired for admitting that there was a direct link between cancer and heavy usage, it really seems like the conspiracy theorists might be right on this one. Besides, my neighbor was recently diagnosed with a malignant glioma and he got from a satellite dish that he got from http://www.satelliteinternet.com/dish-network-internet that he was using for 10 years right next to his bed on his balcony.

Our brain is the most complex and unknown part of the human body, and also very sensitive. It suffers from many risks. Living in a city is risky. Speaking on the cell is risky (oops, perhaps not!), eating wrong foods is risky. Luckily there are things there are just meant to be good for your brain - brain fitness programs. When scientifically validated, these programs may change your life for the better. I recommend one that is available online, it is for free: CogniFit. http://www.cognifit.com/

Put a sea of cell phones under a cage housing cancer-sensitive lab rats and call me in the morning.

Ionizing radiation (gamma, X-rays, K-rays) can cause cellular genetic damage, which the body can and does repair. Your body is naturally radioactive, from carbon, potassium (and other) isotopes. Ionizing radiation does not cause cumulative damage, unless the dose is high, such as exposure to unshielded reactor fuel, atomic bomb blasts, etc. Other radiation, such as Beta and Alpha particles, can be very hazardous if ingested if inhaled. Cell phones do not produce ionizing radiation.

Magnetic radiation is similar to the earth's magnetic field. There's evidence that intense magnetic fields - such as near a dynamo or a Tokamak - cause a rare brain cancer: astrocytoma. The earth's magnetic field (800 milligauss) dwarfs magnetic fields encountered by the public (the voice coil in a cell phone).

Electric radiation are fields encountered in proximity to power lines, thunderstorms, and nerve conduction in the body. That said, exposure to almost any electric field encountered (the power supply in a cell phone) is insignificant compared to that within one's own body's nervous system.

Microwave radiation (RF, radio frequency) is used by cell phones to communicate. Exposure to high levels of microwave radiation generally produce only "thermal effects". There is some limited evidence that exposure to high levels of microwaves can denature proteins. Again, at levels way, way, way, way above anything encountered from a cell phone.

So we see there's no mechanism for a cell phone to cause/contribute to cancer.
