Radiofrequency radiation from cell phones is non-ionizing and is not powerful enough to cause cancer. Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
In April, the city of Berkeley, Calif., won a major decision in a federal appeals court, allowing the city to go forward with its ordinance requiring cellphone retailers to provide consumers with information about safe cellphone use. The court denied a request by the the mobile phone industry's lobby, CTIA-The Wireless Association, which had fought the city’s attempts to educate its citizens.
The microwave irradiation was performed at bands corresponding to mobile devices (GSM) using a modified AP5200 generator (D-LINK, China), operating in four bands (860–910 MHz frequency range, Pout 29 dBm), and to wireless router (WLAN) using a D-LINK wireless router 802.11 g/2.4 GHz (2.412–2.48 GHz frequency range, Pout 19 dBm). In the irradiation chamber there is one stick antenna placed in the center of the ceiling. The exposure levels where chosen in agreement with the microwave irradiation levels measured in open space for heavily used GSM networks (100 mW/m2) and for indoor WLAN (70 mW/m2) communication protocols.

Present study was under taken to predict the possible DNA damages (genotoxicity) and carcinogenicity caused by radiofrequency radiations (RF) to living tissue. Dry seeds of chickpea were treated with GSM cell phone (900 MHz) and laptop (3.31 GHz) as RF source for 24 and 48 h. Untreated seeds were used as (0 h) negative control and Gamma rays (250 Gray) as positive control. Plant chromosomal aberration assay was used as genotoxicity marker. All the treatment of RF inhibits seed germination percentage. 48 h laptop treatment has the most negative effect as compared to untreated control. A decrease was observed in mitotic index (M.I) and increase in abnormality index (A.I) with the increase in exposure duration and frequency in (Hz). Cell membrane damages were also observed only in 48 h exposure of cell phone and laptop (RF). Maximum nuclear membrane damages and ghost cells were again recorded in 48 h exposure of cell phone and laptop. The radiofrequency radiations (900 MHz and 3.31 GHz) are only genotoxic as they induce micronuclei, bi-nuclei, multi-nuclei and scattered nuclei but could be carcinogenic as 48 h incubation of RF induced fragmentation and ghost cells. Therefore cell phones and laptop should not be used unnecessarily to avoid possible genotoxic and carcinogenic effects.
A 2012 study by NCI researchers (25) compared observed glioma incidence rates in U.S. SEER data with rates simulated from the small risks reported in the Interphone study (6) and the greatly increased risk of brain cancer among cell phone users reported in the Swedish pooled analysis (19). The authors concluded that overall, the incidence rates of glioma in the United States did not increase over the study period. They noted that the US rates could be consistent with the small increased risk seen among the subset of heaviest users in the Interphone study. The observed incidence trends were inconsistent with the high risks reported in the Swedish pooled study. These findings suggest that the increased risks observed in the Swedish study are not reflected in U.S. incidence trends.
8. 911 is free—call for an emergency. “Your cell phone is one of the greatest tools you can own to protect yourself and your family in dangerous situations – with your phone at your side, help is only three numbers away. Dial 911 or another local emergency number in emergencies such as a fire, traffic accident, road hazard or medical emergency. Remember, an emergency call is a free call on your cell phone!” – Cell Phone Safety Tips, Mize Centers; Twitter: @mizesales1
The aim of this study was to investigate electromagnetic radiation (EMR) transmitted by wireless devices (2.45 GHz, 3h/day for 30 days), which may cause physiopathological or ultrastructural changes, in the testes of rats and address if the supplemental gallic acid (GA) may reduce these adverse effects. EMR only group was shown to have higher oxidative stress, decreased testosterone and VEGF levels, increased prostaglandin E2 and CGRP, as well as decreased numbers of spermatozoa. Long term EMR exposure resulted in testicular physiopathology via oxidative damage and inflammation. GA may have ameliorative effects on the prepubertal rat testes physiopathology.
In June of 2008, a Japanese study, published in the British Journal of Cancer, considered how mobile phone radiation levels affected different parts of the brain. After studying the mobile phone use of 322 brain cancer patients and 683 healthy adults, the study concluded that using a mobile phone "regularly" did not increase the risk of brain cancer.
No, it isn’t. It is true that International Agency for Research on Cancer (part of the World Health Organisation) has classified radiofrequency electromagnetic fields, including radiofrequency electromagnetic fields from wireless phones as ‘2b’ in its monographs on the evaluation of carcinogenic risks to humans. But that’s by no means proof of danger. You see 2b is ‘possibly carcinogenic’ and as well as Wi-Fi, the category includes coffee, carpentry and pickled vegetables. Some evidence has to be present (except when insufficient evidence is accepted) but the case does not have to be proven.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
