The declaration is based on evidence in the study of those who use cell phones extensively. Known, high intensity use of mobile phones resulted in an increased risk of glioma, a malignant form of brain cancer.
Conclusions drawn the International Agency for Research on Cancer (IARC), the agency under the WHO, applies to radio frequency electromagnetic radiation in general, although most research in this area centered on cellular phone.
The findings are the culmination of the IARC meeting attended by 31 scientists from 14 countries to examine hundreds of results of previous studies that have been published about the cancer risks posed by electromagnetic fields.
Jonathan Samet, a scientist at the University of Southern California, who led the group stated, "There may be some risk, and therefore we should keep a close link between cell phones and cancer."
In the field of radio frequency refers to as "possibly carcinogenic", WHO has put them on par with about 240 other harmful agents, including low-level magnetic fields, powder, and worked as a dry cleaner.
The report found no clear mechanism for the waves cause brain tumors.Radiation from mobile phones is too weak to cause cancer by breaking the DNA, which led scientists to look for other causes.
"We found some common thread that tells us how the cancer can occur but there are gaps and uncertainties," said Samet.
Christopher Wild, Director of IARC, said that in looking at the potential implications for public health, there should be more research on long-term mobile phone use. "Pending the availability of such information, it is important to take pragmatic steps to reduce exposure such as hands-free devices or SMS," he said.
