From the Guidelines

No, there is currently no conclusive evidence to suggest that Bluetooth causes cancer [ 1 ].

Key Points to Consider

  • The provided evidence does not directly address the relationship between Bluetooth exposure and cancer [ 1 ].
  • However, as a precautionary measure, it is recommended to limit exposure to Bluetooth radiation by using devices in moderation, keeping them away from the body when not in use, and using headphones or speakerphone when making calls.
  • Individuals can take steps to reduce their overall exposure to radiofrequency energy by turning off devices when not in use, using wired connections instead of wireless, and keeping devices on a table or desk instead of in a pocket or against the body.
  • It is essential to follow proper usage guidelines and safety precautions when using Bluetooth devices to minimize potential risks, such as being aware of the potential vulnerability of Bluetooth technology to cyber attacks [ 1 ].

Important Considerations

  • The evidence highlights the importance of cybersecurity and privacy concerns related to the use of home monitoring technologies, including those that use Bluetooth [ 1 ].
  • While the focus is on privacy and security, it is crucial to consider the broader context of device usage and potential health implications.
  • Limiting exposure to Bluetooth radiation and taking steps to reduce overall radiofrequency energy exposure can be seen as a prudent approach, given the current state of knowledge [ 1 ].

From the Research

Exposure to Bluetooth and Cancer Risk

  • The question of whether exposure to Bluetooth wireless technology causes cancer is a complex one, and the available evidence is not directly relevant to Bluetooth specifically, as most studies focus on the health effects of radiofrequency (RF) radiation from cell phones and other sources 2, 3, 4, 5.
  • However, it is worth noting that Bluetooth devices do emit RF radiation, although at much lower levels than cell phones 6.
  • Studies on the health effects of RF radiation have yielded mixed results, with some suggesting a possible link to cancer risk, while others have found no association 2, 3, 4, 5.
  • A review of epidemiological evidence on mobile phone use and tumor risk found that the existing evidence does not demonstrate an increased risk within approximately 10 years of use for any tumor of the brain or any other head tumor 3.
  • Another study found no evidence of a causal association between wireless phone use and brain tumors in young people, although the authors noted that the study had limitations and could not rule out a small increased risk 4.
  • A review of epidemiological studies on mobile phone use and cancer risk found that all studies approaching reasonable latencies found an increased cancer risk associated with mobile phone use, although the authors noted that the studies had methodological deficiencies 5.
  • A more recent essay discussed the controversy surrounding the health effects of 5G telecommunications systems and the lack of conclusive scientific evidence on the issue, highlighting the need for more research and caution 6.
