Mobile phones not responsible for brain tumors
Mobile phones not responsible for brain tumors scientists say
Despite the recent tendency to label mobile phones as potentially cancerous...
...accumulating scientific evidence points to a lack of association between the use of mobile phones and brain tumors, according to a study published at Environmental Health Perspectives.
An extensive review of previous studies on the subject, conducted by expert teams from Great Britain, the United States and Sweden, led to the conclusion that there is no convincing evidence of a mobile phone – brain tumor association.
The experts reported that although there is still some uncertainty, the scientific facts point to the direction that mobile phones do not cause brain tumors.
It is worth noting that this report was published two months after the International Agency for Research on Cancer (IARC) and the World Health Organization decided to classify the use of mobile phones as potentially cancerous for people.
The two conclusions are not necessarily contradictory. IARC is trying to categorize the danger based on a predetermined categorization system. Other materials that have been classified as potentially cancerous according to IARC include led and coffee.
The use of mobile phones has risen dramatically since the 1980’s with almost 5 billion devices being used globally, while the instances of brain tumors have not risen accordingly.
For the review, data from more than 13,000 mobile phone users over 10 years, were used.
The scientists analyzed the results, but concluded that there is no clear answer yet and that the cases they examined had many limitations, as it was often the case that they would ask the participants to evaluate or remember past events.
