Cell phones don't raise cancer risk: study
(Reuters)Updated: 2006-12-07 17:06
Using a cellular phone does not increase a person's risk of
cancer, according to a broad study released on Tuesday involving more than
400,000 Danish cellular telephone users.
A team of researchers used data on the entire population of Denmark to determine that neither short- nor long-term use of cellular phones, also called mobile phones, was linked to a greater risk of tumors of the brain and nervous system, salivary gland or eyes, leukemia or cancer overall.
It is estimated that more than 2 billion people worldwide use cellular phones.
"I think the results of this study are quite reassuring," Joachim Schuz of the Danish Institute of Cancer Epidemiology in Copenhagen, the lead researcher, said in an interview by cellular phone from Denmark.
The study, one of the most comprehensive to date, represented the latest evidence endorsing the safety of cellular phones. The data available to the researchers allowed them to look at a large number of cell phone users and assess potential risks many years after they first used them.
"The big advantage is a whole nation is included in the study," Schuz said.
The phones emit electromagnetic fields that can penetrate into the brain, and some scientists have sought to determine if this could cause cancer or other health problems.
Schuz's team studied data on 420,095 Danish cell phone users (357,553 men and
62,542 women) who first subscribed for mobile service between 1982 and 1995 and
were followed through 2002 -- meaning some were tracked for two decades. The
researchers then compared their cancer incidence to the rest of Denmark's
population.
