Technology myths: what do the facts tell us?

Technology is advancing rapidly these days, but there are also myths that raise concerns. One of the most persistent is the idea that waves from cell phones and wifi networks can cause cancer. Is this claim true? In this article, we will break down the truth behind these fears, based on recent scientific research and the principles of electromagnetic radiation.

Understanding waves: the science of non-ionizing radiation

To address this topic, it is essential to distinguish between the different types of electromagnetic radiation. Cell phones and wifi use non-ionizing radiation, which does not have the energy to disrupt atoms or directly damage DNA. Instead of causing damage, this form of radiation causes mild heating of tissues, similar to what occurs in a microwave oven. Therefore, although cell phone use may heat the skin slightly, there is no evidence to suggest that this causes significant damage.

Scientific evidence: what the studies say

Several studies have investigated the possible link between cell phone use and cancer. Here we present you some of the most relevant ones:

• Interphone research: This extensive study, conducted by the International Agency for Research on Cancer (IARC), interviewed 5,000 people in 13 countries and found no significant increase in cancer cases related to cell phone use.
• Copenhagen Study: Over 30 years, data from Danes who used cell phones before 1995 were compared with those who did not, concluding that there was no increase in cancer rates among cell phone users.
• Million Women Study: This study, which included more than one million women in the United Kingdom, also found that there was no association between prolonged cell phone use and cancer risk.
• Recent reviews: Recent studies, including a 2024 review, reaffirmed that there is no evidence connecting cell phone use with an increased risk of brain cancer or childhood leukemias.

Scientific perspectives: a solid consensus

Alberto Nájera, professor at the University of Castilla-La Mancha and director of the Scientific Advisory Committee on Radio Frequencies and Health, points out that the conclusions reached are robust and supported by multiple quality studies. It has been determined that exposure to non-ionizing radiation, such as that from cell phones, does not increase the risk of cancer.

Myths and realities: understanding the context

It is important to remember that zero risk does not exist in our daily activities. However, the scientific consensus is clear: cell phone use is not associated with an increased risk of cancer. In fact, factors such as pollution, diet and tobacco use are much more detrimental to health.

Conclusion: the importance of accurate information

The next time you come across an alarmist article about cell phone use and its link to cancer, keep in mind that there is a large research base that supports the safety of these technologies.
