View Original AbstractThis 1990s study of early analog phones found no cancer increase, but doesn't address today's smartphone radiation levels.
Plain English Summary
Danish researchers tracked over 420,000 cellular phone users from 1982 to 1995 and compared their cancer rates to the general population. They found cell phone users actually had lower overall cancer rates than expected, with no increased risk for brain tumors, salivary gland cancers, or leukemia. The study found no connection between phone use duration and cancer risk.
Study Details
The aim of this study is to investigate Cellular Telephones and Cancer-a Nationwide Cohort Study in Denmark.
A retrospective cohort study of cancer incidence was conducted in Denmark of all users of cellular t...
Overall, 3391 cancers were observed with 3825 expected, yielding a significantly decreased standardi...
The results of this investigation, the first nationwide cancer incidence study of cellular phone users, do not support the hypothesis of an association between use of these telephones and tumors of the brain or salivary gland, leukemia, or other cancers.
