The longer someone talks over the phone – in terms of hours and years – the more likely is he/she to develop glioma, a deadly form of BRAIN CANCER, says a new study.

Brain tumour rates were three times more among people, who spoke on CELL or CORDLESS PHONES after more than 25 years than those who did not use them, the findings showed.

“The risk is three times higher after 25 years of use. We can see this clearly,” Lennart Hardell, lead researcher and oncologist from University Hospital in Orebro in Sweden was quoted by Daily Mail as saying.

Swedes who talked on CELL PHONES for over 25 years had three times the risk of one type of brain cancer, compared with people who used those phones for under a year.

For the study, Lennart Hardell and his colleague Michael Carlberg matched 1,380 patients with malignant brain tumours to people without such tumours.

They also compared their phone use.

People who reported using cordless or mobile phones for 20 to 25 years had higher risk of being diagnosed with glioma as compared with those who reported using them for less than a year, the study found.

However, no link was found between WIRELESS PHONES and malignant brain tumours besides glioma, pointed out the study.

A World Health Organization (WHO) panel of 31 scientists from 14 countries classified mobile phones as ‘possibly carcinogenic’ in 2011.

The study appeared in the journal Pathophysiology.

WHO panel warns that cell phone use may cause cancer
Saturday, June 04, 2011 by: Jonathan Benson, staff writer

Scientists from the International Agency for Research on Cancer (IARC), a group affiliated with the World Health Organization (WHO), say that mobile phones are a “possible” carcinogen that may be a cause of cancer. The findings, which support previous research on the subject, add to the growing body of evidence which suggests that the electromagnetic radiation emitted from mobile phones causes serious health problems.

“A positive association has been observed between exposure to the agent and cancer for which a causal interpretation is considered … to be credible,” states the IARC. However, in the same train of thought, the agency claims that evidence is “limited” to suggest that mobile phone usage is linked to glioma or acoustic neuroma, two types of brain cancer.

In 2009, IARC published a study in the Journal of Clinical Oncology that linked mobile phone usage to an 18 percent increase in brain tumor risk. And because it was observed that such tumors tended to form on the sides of brains where mobile phones were primarily used, the connection between the two is even more striking.

Another report issued in 2010 by the International Electromagnetic Field Cooperative (IEFC) also found a link between mobile phone usage and increased rates of brain tumors. Included in this report is a Swedish study that found a 420 percent increase in brain cancer rates among children who began using mobile and cordless phones as teenagers, as opposed to those that did not.

With all of this research now available and the latest announcement from IARC, one would think more people would be concerned about the risks involved with the excessive use of mobile phones and looking for less-risky alternatives or using hands-free devices at the very least. But because the period between when a cancer patient is exposed to this radiation and when he or she develops tumors typically spans several decades, some experts claim that the link between the two is inconclusive and are content to tell the public there is really little to worry about.
