No. There is no evidence that suggests Bluetooth headphones can cause cancer. The rumours that Bluetooth causes cancer has spread like a wildfire after the World Health Organisation (WHO) in 2011 classified radiofrequency electromagnetic fields as ‘possibly carcinogenic to humans based on an increased risk for glioma, a malignant type of brain cancer associated with wireless phone use’.
Bluetooth devices also emit radiofrequency that has made people talk about it in an attempt to blow the whistle against an increase in the cases of cancer globally. However, a study has shown that the radiation exposure by Bluetooth is 10 to 400 times less than the radiation from cell phones. It means if cell phones do not cause cancer, Bluetooth will not inevitably cause cancer.
Nevertheless, radiation causes cancer, which raises the question of whether the long-term exposure to the radiation released by all common household Bluetooth devices can cause cancer. Further research is needed to understand the link between Bluetooth and cancer. We live in a generation that relies on Bluetooth for personal use and work. The prolonged use of Bluetooth has made the exposure to radiation widespread, even in public places.
