Concerns about the potential link between modern technology and brain tumours have surged in recent years, particularly regarding Wi-Fi, smartphones, and screen time. However, experts assert that there is currently no strong evidence indicating that these factors directly cause brain cancer. The World Health Organization and other health organizations have found no definitive proof linking normal mobile phone or Wi-Fi use to brain tumours. Research shows mixed results, with older studies suggesting a slight increase in rare tumours among heavy phone users, while newer studies fail to confirm a consistent connection. Excessive screen time can negatively impact health, leading to issues like eye strain, poor sleep quality, and increased anxiety, but it does not directly cause brain tumours. Stress is often cited as a culprit for many health issues, yet there is no scientific evidence proving it directly triggers brain cancer. Instead, brain tumours typically result from complex genetic mutations and other known risk factors. Experts recommend focusing on maintaining overall brain health through proper sleep, stress management, and regular exercise.
