Electromagnetic radiation, commonly referred to as radio waves, emitted by mobile phones and other devices, is not shown to raise cancer risk, even when the device stays close to the body. This conclusion comes from Cancer Research UK, a leading independent cancer research organization, and reflects analyses reported by major outlets.
Mobile phones function by receiving radio waves from base stations and converting them into electrical signals. As a result, mobile communications generate electromagnetic waves within the radio frequency range, which are categorized as non-ionizing radiation.
There is a belief that keeping a phone near the body, such as in a pocket, could elevate cancer risk due to radiofrequency radiation. Cancer Research UK notes that ionizing radiation, like X-rays and gamma rays, can damage DNA and contribute to cancer development. The implication is that non-ionizing radiation from phones does not possess enough energy to directly alter DNA at the cellular level. Consequently, the proximity of the device to the body does not determine harm in this context.
Experts also explain that although 4G and 5G networks utilize higher frequency radio waves, the energy involved remains insufficient to cause DNA damage. This distinction helps clarify public concerns about newer wireless technologies and health safety.
Overall, the prevailing evidence indicates no confirmed link between the use of mobile devices and an increased cancer risk attributable to radiofrequency radiation. Continued monitoring and high-quality research are encouraged to keep public health guidance up to date as technology evolves.
