On World Brain Tumour Day 2025, concerns about the possible link between smartphone usage and brain tumours remain widespread, especially among parents and health-conscious individuals. As technology becomes increasingly integral to daily life, questions about its long-term health effects persist.
Dr. Omkar Narayan Churi, Consultant – Neurosurgery at Manipal Hospital, Goa, addressed these concerns, clarifying the scientific consensus on the issue. According to Dr. Churi, current evidence and data from multiple studies indicate that cell phone use has not led to an increased incidence of brain or other cancers. He emphasized that cell phones and their networks operate in the radiofrequency range, which is categorized as ‘low frequency, low energy’ on the electromagnetic wave spectrum. Other common household devices such as radios, ovens, televisions, and computers also emit similar radiofrequency radiation.
While such radiation can cause mild heating in the area where the phone is held, this effect is minimal and does not significantly impact core body temperature. Dr. Churi did note, however, that as technology evolves (for example, with the introduction of new generations like 3G, 4G, and beyond), ongoing research will be essential to monitor any potential changes in health outcomes. He also pointed out that children’s nervous systems are more susceptible to various cancer-causing factors, warranting extra caution for younger users.
Beyond cancer concerns, Dr. Churi highlighted other documented health risks associated with mobile phone use, such as distracted driving and related accidents. He also referenced the rise of “Brain Rot”—Oxford University Press’s Word of the Year for 2024—attributed to excessive consumption of low-quality online content and mindless scrolling, which may contribute to intellectual decline.
Tips for Safer Technology Use
To mitigate potential health risks, Dr. Churi recommends the following:
-
Limit overall cell phone usage
-
Prefer texting over talking when possible
-
Avoid using phones while driving
-
Refrain from making calls when signal strength is weak
-
Use speaker mode or headphones to keep the device away from the head
-
Opt for wired earphones rather than wireless ones to minimize radiation exposure1
He concluded by advising moderation in technology use, likening it to dietary habits: “Technology, like food, should be consumed in moderation for a happier and healthier life”1.
