Do mobile phones cause brain cancer?This has been an ongoing debate for decades, but whenever someone asks this question, it’s usually met with scepticism and the debate is shunned. I used to react the same way. But once I started digging into the evidence, it became clear to me that the answer was much more complex than I had imagined.There are over 6 billion mobile phone subscriptions worldwide, many of them smart phones, with Wi-Fi functionality. Since the widespread use of mobile phones, overall brain cancer rates have not increased and this is often used as proof that mobile phones are safe. But this is short sighted, mainly because brain cancer can take decades to develop and being also rare, it’s unlikely to show up easily in data from the general population. In fact, US statistics do show an increase in brain tumours in younger people.
