The results of the study, published today in the British Medical Journal, indicate that no matter how long you have used a phone for, or how frequently you make and take calls, your risk of developing a brain tumour remains the same.
The survey, conducted by the Leeds, Nottingham and Manchester Universities in conjunction with London's Insititute of Cancer Research, focused on the incidence of glioma - the most common form of brain tumor - in phone users.
The researchers interviewed 966 people, aged 18 to 69 years, with glioma brain tumors and 1,716 randomly selected healthy individuals. They were all asked about their mobile phone usage, including how long they had used mobile phones, the number and duration of the calls they made, and what make and model of phone they had used. The interviews took place between 1 December 2000 and 29 February 2004, and included people in the Thames region, southern Scotland, Trent, the West Midlands and West Yorkshire.
The results contradict earlier studies exploring potential relationships between brain tumour risk and mobile phone usage. [January 20, 2006]
2011. Heavy cell phone users worried that they might be setting themselves up for cancer can breathe easier. The biggest study to look for any connection has found no link. It followed more than 350,000 people for about a decade and says heavy cell phone users have the same cancer rates as people who don't use cell phones. The study, out of Denmark, confirms a smaller one reported on last year (2010). It also confirms the assessments of the Food and Drug Administration and the Federal Communications Commission.
