Cancer: Cell phone cleared

A new study released on Friday shows that the use of mobile over time does not increase the risk of brain cancer.

A new study published Friday by the prestigious British Medical Journal contradicts the results of the International Agency for Research on Cancer (IARC) - Agency of the World Health Organization (WHO) - released late May. This research showed that the use of mobile "possibly carcinogenic to humans".

No correlation
This third successive study reaches the same conclusions as the study in July's Journal of the National Cancer Institute as how the use of the laptop over time would not increase the risk of brain cancer. It was conducted in Denmark over a period of 17 years (1990-2007) to holders of 358,403 subscribers. And the conclusion is that there is no correlation between use of mobile phones and cancer, and that even among subscribers for over 13 years. These results are valid for all types of brain cancer, according to the team led by Patrizia Frei of the Danish Cancer Society.

Of those surveyed, 10,729 central nervous system tumors have been identified, about the same among the subscribers in others. And the risk is the same for men (5111) and women (5618). The rates of glioma and meningioma are similar among users of portable and non-users.

The number of years of subscription offers, according to the study of variations "insignificant." However, researchers do not exclude an increased risk among very heavy users - subscribers of more than 15 years (there are no numbers). Hence the interest, though, to follow the recommendations which advise the authorities to limit exposure by focusing texting and hands free kits. Recall that in 2010 there were more than 5 billion mobile phone users worldwide.
