Talking over mobile phones for just 15 minutes daily or higher ups the risk of brain cancer, which is usually fatal in nature.
The study, which was conducted in 13 countries, says using a mobile phone for just 15 minutes a day can substantially up the risk of brain cancer among its users. The longer people use it, the higher the risk.
A news agency, quoting Elisabeth Cardis, leader of the Interphone Study, said an increased risk of brain tumours, known as gliomas, was seen in the 20 per cent of users with the highest exposure to radio-frequency emissions.
Notably, Gliomas are fatal, usually within three to five years of diagnosis, even with treatment. Also, users may develop cancer close to the area where they held their phones to the head.
Earlier, World Health Organisation too said that mobile phones are cancerous in nature. Many other organisations have also come out recently with studies that have cited adverse effect of radiation of mobile phones on mental and physical health of not just humans but also animals.
