Long or short-term cell phone use is not associated with increased cancer risk, according to a study in the December 6 issue of the Journal of the National Cancer Institute.
The widespread use of cell phones has raised concerns about health risks among users. Cell phone antennas emit electromagnetic fields that can penetrate into the human brain, and scientists have wondered if this might cause tumors in the head or neck.
Joachim Schüz, Ph.D., of the Danish Institute of Cancer Epidemiology in Copenhagen, Denmark, and colleagues performed a study of 420,095 cell phone users who first subscribed between 1982 and 1995 and were followed through 2002 for cancer incidence.
The authors did not observe an association between long or short-term cell phone use and brain tumors, salivary gland tumors, eye tumors, or leukemias. In cell phone users who had subscribed over 10 years, they found no link between cell phone use and brain tumor risk. They suggest that cell phone use is not linked to cancer risk.
"The methods used suggest that the use of cellular telephones does not pose a substantial risk of brain tumors among short-term or long-term users," the authors write.
