Studies looking at long-term mobile phone users are the most likely to report an increased risk of cancers linked to mobile phones. This is because even when people are exposed to some of the strongest known carcinogens, such as ionizing radiation or asbestos, the resulting cancers can take decades to appear. A Swedish study of 750 people by the Karolinska Institute in 2004 found that using a phone for 10 years or more increased the risk of acoustic neuroma, which is a type of benign tumour in the nerve connecting the ear to the brain. The increased risk was not found in those who had been using their phone for less than 10 years.
Right now, evidence from scientific studies around the world is not strong enough to show a link between cell phone use and disease. If scientists were able to show a link, then cell phones would be sold with a warning label. It is understood that cell phones are here to stay, but the question that needs to be answered is not whether we should use cell phones, but how. Using a mobile phone while driving is considered the biggest health risk posed by mobile phones. It can increase your chances of having an accident, and it’s illegal to use a handheld mobile phone while driving or riding a motorbike.
