Cell phone and cancer concern

The relation of the cellular telephone usage and cancer has been a long standing suspicion and commonly contradictory reports have been presented on this subject.

It is prudent to be familiar with the basic physics and marking of the cellular telephones. Cellular telephones emit and receive radio frequency waves from transmission towers located terrestrially. Most of the cellular hand sets rise GSM protocol (Global system for mobiles followed by CDMA protocol (code division multiple access). The cellular telephones can be further divided into analog and digital. The analog phones have greater loss of data while transit, so, to augment it, they transmit and receive signals at higher power in comparison to the digital cellular telephones. This creates an electromagnetic filed which human tissues absorb, which is measured by (SAR) specific absorption ratio.

The international commission on non ionising radiation protection (ICNIRP) has recommended SAR below 2w/kg for users of cellular telephones.

Several researches suggest that mobile suage may be associated with tumours such as astrocytomas, gliomas and acoustic neuromas.

However, research into this field is fraught with certain drawbacks, such as recall bias, inaccurate radiation dose quantification, selection bias and so on. Animal studies have provided no consistent relation between cancer and non-thermal range exposure. Based on the human studies reviewed, certain factors come forth as having a possible risk towards development of cancer, such as use of analog or cordless phones, predominant unilateral usage and exposure for more than 10 years.

A special concern is the young adults of children population at large who use cellular telephones indiscriminately. While it may well be prudent to avoid these practices, it must be emphasized that clear, long-term cohort studies have not been conducted to prove any causative role of mobile phone radiation in cancer pathogenesis.
