Cell phones and tumor: still in no man's land.

ABSTRACT

The use of cell phones is increasing worldwide at a phenomenal pace. While cellular communication has dramatically influenced our lifestyle, its impact on human health has not been completely assessed. Widespread concern continues in the community about the deleterious effects of radiofrequency radiations (with which cell phones operate) on human tissues and the subsequent potential for carcinogenesis. A detailed survey of published studies researching this question was done in preparation of this manuscript. Included in the survey were case reports, in vitro studies, population based retrospective studies and other investigations. The database of indexed journals was searched for key words like 'cell phone', 'radiation', 'cancer' and 'radio waves'. Guidelines issued by the World Health Organization, federal and technical authorities, Institute of Electrical and Electronic Engineers and the International Commission for Non-Ionizing Radiation Protection were reviewed. The evaluation of current evidence provided by various studies to suggest the possible carcinogenic potential of radiofrequency radiation is inconclusive. This risk assumes significance in light of the burgeoning number of people who are continually exposed to the high frequency radiation from cell phones and towers that serve as receiving and transmitting stations. The aim of this review is to identify limitations in past studies, present available data for consideration, and identify gaps in the current knowledge base. This will provide impetus and direction for further research and allow informed decisions pertaining to cell phone use to be made.
