The use of the cellular does not cause brain tumor or so it seemed. The news, fresh publication on the pages of International American Journal of Epidemiology Is the result of a ‘investigation funded by the International Agency for Research on Cancer (IARC). “The results do not permit us to tell that there is some risk linked with the use of mobile phones, but it is premature to state that the risk does not exist” concluded Christopher Wild, Director of IARC. In short, the evidence so far is reassuring, but it is yet early to tell how things really are.
The learn known Interphone lasted more than 10 years and involved 13 countries, for a total expenditure of 19 million euros. A project lately, which aimed to give a definitive reply. Over 5 thousand people between 30 and 59 years, affected by brain tumor, glioma or meningioma were interviewed as regards the frequency of mobile phone use in the period before development of brain disease. The responses were then compared with those given by 7 thousand healthy subjects.
The results have shown no direct correlation between the sustained use of mobile and the two types of tumor With the exception of increased exposure to glioma subjects who spent numerous hours with the phone attached to your ear. “This result – described Paolo Vecchia, Who go behind the search in our country – is possibly distorted by psychological reasons: the patient has possibly inadvertently exaggerated the time spent in mobile. The confirmation is that this increase occurs merely in the last collection of users, and not gradually. Furthermore, merely among the patients there who said use of over 12 hours a day, or even in years when the phone had not still been invented “.
The researchers take to specify, but not at all like that in this case requires further investigation. Also because, in current years habits changed completely: the average time spent on the cellular is definitely higher, as increased subscriptions to services mobile. We merely a few weeks past we talked about the new project an investigation that lasted 30 years and involve 250 thousand participants. Not have to wait for proof.
