No. There are no studies that suggest WiFi causes cancer. Like mobile phones, WiFi also emits radiofrequency electromagnetic fields. A study has shown that non-ionizing radiation in the frequency range 30kHz-300GHz is carcinogenic for human beings.
Another study shows that WiFi mostly works at 2.4 GHz and 5 GHz of radiation. These numbers show that human radiation exposure caused by WiFi is low and ‘possibly may not cause’ brain or central nervous system cancer. Likewise, no evidence confirms that wireless bluetooth headphones cause cancer. The common household electronic devices emit low radiation and do not cause cancer. But it mostly depends upon the way people use these devices. In the context of mobile phones, evidence does not confirm that they cause cancer. Using mobile phones in the dark causes eye cancer. However, the human body absorbs radiofrequency radiation that people usually encounter as heating of the exposed area. Although mobile phones do not increase body temperature, ‘cancer caused due to excessive use of mobile phones’ cannot be ruled out completely. The common household electronic devices emit low radiation and do not cause cancer. But it mostly depends upon the way people use these devices.
A study recommends people maintain a distance from electronic devices at home. If not cancer, keeping the electronic devices close can affect memory, blood-brain relation and DNA structure. However, an error in the altered DNA structure can cause deadly diseases like cancer.
Research says that long-term exposure to 2.4GhZ can alter the human DNA, but further research is needed to understand the link between radiofrequency radiation and cancer. The potential of radiofrequency to cause cancer cannot be ruled out completely still advanced research is required to assess the possible DNA damage that radiation can cause.
