A large study in Denmark, of some 420,000 people has reported that there is no statistical evidence that mobile phone usage leads to an increase of cancers. Danish ccientists tracked 420,000 Danish cell phone users, including 52,000 who had used mobile phones for an excess of 10 years, and some who started using them 21 years ago.
The scientists matched mobile phone records to the Danish Cancer Registry, which records every person who gets cancer and reported in the Journal of the National Cancer Institute that there was no noticeable rise in cancer.
"We found no evidence for an association between tumour risk and cellular telephone use among either short-term or long-term users," said Christoffer Johansen, of the Danish Institute of Cancer Epidemiology, who led the research. "Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded."
The scientists were given access to details of all 723,421 people who had a mobile phone in Denmark between 1982 and 1995. Just over 200,000 corporate customers were removed as the individual person who used the phone could not be identified. A further 100,000 were eliminated because of duplicated addresses or errors, leaving the 420,000 for the study.
The health of the remaining phone users was tracked until 2002, where a total of 14,249 cases of cancer were recorded. Statistically, for that sample size - they would have expected about 15,000 cases of cancer under normal conditions. The fact that the reported figure did not exceed the expected tally suggests that there is no risk of cancer from using cellphones."
