DailyTech published an article where a British neurosurgeon’s study concluded that mobile phones are more dangerous than smoking and even asbestos:
The number of users is the first aspect to look at, says Dr. Khurana. Over 3 billion people worldwide use a cell phone, according to Dr. Khurana. Only about one billion people worldwide smoke, evidence to his claims. The smoking population incurs approximately five million worldwide smoking related deaths a year.
The doctor expresses no uncertainty about whether cell phones cause cancer. He states emphatically, “there is a significant and increasing body of evidence for a link between mobile phone usage and certain brain tumors.”
