Occupational Diseases: Study Says No Cell Phone-Cancer Link

An investigation that studied cellular phone users in Denmark over a span of decades has concluded that cell phones have no effects on rates of cancer. The Danish Institute of Cancer Epidemiology, who conducted the study, looked at 420,000 cell phone users for up to 21 years. Cell phone users were shown to have the same chance of developing cancer as the general population.

No Cell Phone-cancer Link, Study Says

Researchers looked at Danish residents, more than half of whom had begun using a cell phone between 1982 and 1995. Lead researcher Christoffer Johansen said that "We found no evidence for an association between tumor risk and cellular telephone use among either short-term or long-term users. Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded."
