Brain Tumors and Mobile Telephones
Cell phones emit radiofrequency energy, and their constant usage close to your ear has raised suspicion that the increasing brain tumors, such as gliomas, meningiomas especially among youth and adolescence could be linked to such non-ionic radiation.
The scare of acquiring brain tumors and its link with the use of mobile cell phones has been dispelled by some recent studies.
An EUROPEAN study involving nearly 1000 participants has found no link between mobile phone use and brain tumors among children and adolescents, a group that may be particularly sensitive to phone emissions.
A study, published in the Journal of the national Cancer Institute revealed the concerns of younger individuals brains being more vulnerable to adverse health effects of constantly using cell phones and after effects of exposure to radiation.
Research has revealed that there is no increase in brain tumors among children in the US and many parts of Europe who constantly are using mobile phones and from the resulting emissions. It is also observed that most youths start to use mobile phones quite young do absorb twice the amount of cellphone energy more than adults.
The Interphone Study
Gliomas linked to cell phones
There are still three main reasons why people are concerned that constant use of cell phones may cause certain types of cancers.
Radiofrequency energy is a form of electromagnetic radiation. There are two types: ionizing (x-rays, radon, cosmic rays) and non-ionizing (radio-frequency, extremely low frequency or power frequency). Ionizing radiation from x-rays can cause cancer. Mobile phones emit non-ionizing radiation, which has enough energy to cause atoms in a molecule to vibrate, but not enough to remove electrons. Sound waves and visible light waves are other examples of non- ionizing radiation. So far, there is no evidence that non-ionizing radiation emitted from cell phones have caused cancer risk.
The radiofrequency energy affects your body in many ways:
The number and duration of calls
There are beneficial effects from radiofrequency energy, such as when used for heating, a form of this is used by microwave ovens. High doses of this energy could cause localized tissue heating. Low dosage equipment is used by health personal and physiotherapists to relieve chronic recurrent lower backaches and degenerative cervical (neck) problems,
It has been observed that there had been no adverse effects on U.S. Navy electronics technicians or fire control technicians working in electromagnetic pulse test program, cellular phone manufacturing workers, or Navy personnel with a high probability of exposure to radar.
It has been shown that radiofrequency energy does not appear to result in damage to DNA. To date, studies of rodents exposed to radiofrequency radiation provide no clear or consistent evidence that neither this type of radiation causes cancer, nor that it enhances the carcinogenicity of known chemical carcinogens.
The International Agency for Research on Cancer (IARC), a component of the World Health Organization, has recently classified radiofrequency fields as “possibly carcinogenic to humans,” based on limited evidence from human studies, limited evidence from studies of radiofrequency and carcinogenicity in rodents, and weak mechanistic evidence (from studies of geno-toxicity, effects on immune function, gene and protein expression, cell signaling, oxidative stress, and apoptosis, along with studies of the possible effects of radiofrequency energy on the blood-brain barrier).
The American Cancer Society states that most studies to date have not found an association between cell phone use and development of tumors. However, results from these studies have been limited by the length of follow-up, changing patterns of cell phone usage and technology, lack of study of children, and methods for measuring cell phone use. Possible cancer risks of cell phone exposure should continue to be evaluated using high-quality methodological approaches, particularly in relation to use in childhood and adolescence and longer-term use.
