Cellphones increase brain tumour incidence - New Researches

STUDY # 1) RF-EMF emissions from wireless phones are class 1 human carcinogens

Using the long-established and respected Bradford Hill criteria for assessing causality, a research paper by Lennart Hardell and Michael Carlberg (Rev Environ Health 2013-0006, De Gruyter; DOI 10.1515) shows that; RF-EMF exposure from mobile (and cordless) phones should be regarded as an IARC class 1 human carcinogen (cancer causing agent). Current guidelines for exposure need to be urgently revised.

Wireless phones, i.e. mobile phones and cordless phones, emit radio frequency electromagnetic fields (RF-EMF) when used. An increased risk of brain tumors is a major concern. The International Agency for Research on Cancer (IARC) at the World Health Organization (WHO) evaluated the carcinogenic effect to humans from RF-EMF in May 2011. It was concluded that RF-EMF is a group 2B, i.e. a "possible", human carcinogen.

STUDY # 2) Case-control study of the association between malignant brain tumours diagnosed between 2007 and 2009 and mobile and cordless phone use.

This new study confirms previous results of an association between mobile and cordless phone use and malignant brain tumours. The findings provide support for the hypothesis that RF-EMFs play a role both in the initiation and promotion stages of carcinogenesis.

Previous studies have shown a consistent association between long-term use of mobile and cordless phones and glioma and acoustic neuroma, but not for meningioma. When these phones are used they emit radiofrequency electromagnetic fields (RF-EMFs) and the brain is the main target organ for the handheld phone emissions.
