Is a Bluetooth Headset Causing Brain Cancer? Here's the Medical Explanation

JAKARTA - Since bluetooth headphones and headsets have become part of everyday life, a new concern has emerged, whether these wireless devices that stick close to the head can increase the risk of brain cancer?

This issue is often circulating on social media and health forums, making many people wonder if the habit of listening to music or receiving calls via bluetooth is dangerous.

To answer it, we need to first understand the type of radiation emitted by this device and how it affects the human body.

Radiation is generally divided into two large groups, namely ionizingradiation and non-ionizing radiation.

Ionizing radiation is a type of high-energy radiation that can damage cells and DNA. Examples include X-rays, gamma rays, and radiation from certain cancer therapies. Exposure in large doses is known to increase the risk of cancer.

In contrast, devices such as cell phones, Wi-Fi, and Bluetooth headphones emit non-ionizing radiation in the form of radiofrequency waves. The energy is much lower.

"Non-ionizing radiation does not have enough energy to directly damage DNA, so the biological risk is much smaller than ionizing radiation," said Dr. Jon Glass MD, a neurologist, quoted from the Jefferson Health website.

Several studies have shown that Bluetooth's radiation is much weaker than a mobile phone that is directly attached to the ear when making a call.

Concerns have arisen because Bluetooth headphones are used close to the brain and are often worn for long periods of time. However, until now, scientific evidence showing a direct link to brain cancer has not been found.

"Until now, there is no strong evidence that the use of bluetooth devices increases the risk of brain tumors. If there is a significant risk, the medical community must have issued an official warning. This means that, based on current medical knowledge, the use of bluetooth headphones within reasonable limits is considered safe from the side of cancer risk," said Dr. Glass.

Interestingly, experts are actually more worried about hearing damage due to the use of headphones with too high volume and long duration. The problem that is more often encountered is not a brain tumor, but hearing loss due to continuous exposure to loud sounds. So, it's not the radiation that needs to be feared, but the habit of listening to audio with maximum volume.

Until now, the exact cause of most brain cancers is still unknown. However, there are several known risk factors, such as:

- Past high-dose ionizing radiation exposure (e.g. radiation therapy for other cancers)

- Certain genetic factors

- Family history with several types of cancer

Beyond that, most cases appear without a clear cause.

If the goal is to avoid brain cancer, there is no strong medical reason to stop using bluetooth headphones. Reducing usage may be a personal precaution, but it is not a health obligation.

The more important thing is to keep the volume below 60 percent, give a break after long use, avoid sleeping while wearing earbuds. This technology is designed with strict safety standards. As long as it is used reasonably, you can still enjoy music, podcasts, or phone calls without having to be haunted by excessive fear.
