New WHO Study Links Cell Phone Radiation to 2 Types of Cancer

WHO-Backed Study Links Cell Phone Radiation to Cancer: What You Need to Know

At WaveBlock®, our goal has always been to keep men, women, and especially children safe from the potential dangers of electromagnetic field (EMF) radiation. In our modern world, we are constantly surrounded by EMF pollution from things like hot spots, WiFi networks/routers, cell phones, laptops, and many other tech innovations we rely on daily. 

While EMF radiation may be invisible, the potential side effects of long-term radiation are not. The team at WaveBlock® hears from customers all the time who experienced migraines, headaches, fatigue, stress, sleep disruption, and many other health issues before using WaveBlock® stickers on their tech devices.

As our dependence on tech grows so does the conversation around the potential negative health effects of prolonged EMF radiation exposure. While tech companies don’t want you to know this info, several scientists are conducting research to find correlations between EMF exposure and things like infertility, mental health concerns, and even possible links to cancer. While scientists continue to investigate, there is certainly ample cause for concern at the very least. 

While naysayers will point to not enough evidence, the lack of evidence is part of the problem. Think about it this way. When cigarettes first became commonly used, people weren’t concerned about health effects or lung cancer. Now that many years have passed since the introduction of cigarettes, we have plenty of evidence to show negative health correlations. Because we didn’t depend on tech so heavily until recently, it may take more time for researchers to compile ample evidence for the correlation of tech radiation to negative health concerns. However, that doesn’t mean there isn’t cause for concern.

A major new study commissioned by the World Health Organization (WHO) has found "high certainty" that exposure to wireless radiofrequency (RF) radiation causes cancer in tested animals. Published in Environment International in May of 2025, the systematic review analyzed decades of animal research and concluded that RF radiation, like that emitted by cell phones, can lead to malignant tumors. 

Let’s talk more about what this 2025 study showed.

A New 2025 WHO Study Finds Correlation Between EMF Radiation & Cancer

The WHO-backed study identified two specific types of cancer with strong links to RF radiation exposure. After testing animals, there was “high-certainty evidence” linking EMF radiation from wireless devices (such as cell phones, wireless earbuds, and laptops) to two types of malignant tumors — gliomas of the brain and shwannomas of the heart.

• Gliomas are aggressive brain tumors. They are rare and cancerous 80% of the time. Glioblastomas are the most aggressive type of this form. This 2025 study confirms what other human-based studies have observed in long-term cell phone users. 

• Schwannomas are rare tumors of the nerve sheath, typically found in the heart. These tumors are typically benign, but can cause serious health issues such as balance concerns, brain pressure, hearing loss, and more. Other scientific studies have linked prolonged cell phone use to vestibular schwannomas in human epidemiological studies.

• The study also found “moderate-certainty evidence” for increased risk of tumors in the adrenal glands, liver, and lymphatic system.

As more research is done, the more WaveBlock® finds that scientists are calling for lowering current federal safety limits of SAR levels heavily to adequately protect men, women, and children. 

“We cannot afford to ignore this study,” said Theodora Scarato, the Director of the Wireless and EMF Program at Environmental Health Sciences. “Scientific evidence must guide policy.”

While animal studies don’t always directly translate to human health, the fact that studies find risk in animals shows cause for concern. 

Why Are People Convinced That Tech Radiation Can Result in Cancer?

Aside from scientific studies like the one mentioned, there are two large reasons that people are concerned about EMF radiation and its potential to cause cancer. One reason is that cells generate reactive oxygen species (ROS) when exposed to EMF radiation. This can lead to DNA damage and oxidative stress, which are common markers of cancer initiation and progression. 

The second reason is that EMF radiation has been proven to disrupt several of the human body’s biological functions, especially within hormones and the endocrine system. Things like interrupted circadian rhythms can cause sleep disruptions and disrupting hormone patterns can negatively impact fertility, growth, and more. Maintaining cellular homeostasis (performed by hormone regulation) is a key factor in suppressing tumor growth. 

Additionally, brain and nervous system cancers are of large concern due to wireless earbuds and cell phones being used very closely to the brain and body. This means even low levels of EMF radiation are being emitted very close to your vital organs and tissue.

Why Does This Study Matter?

In 2011, the International Agency for Research on Cancer (part of WHO) classified EMF radiation as a Group 2B possible human carcinogen. It cited previous, limited animal studies at that time. Since then, larger studies have continued to report that EMF exposure has caused cancer in animals. This growing evidence adds pressure for the IARC to re-evaluate its classification of EMF radiation as a possible carcinogen. It’s no wonder that several scientists and researchers are calling for change to the FCC’s current regulations — which haven’t been updated since the late 1990s!

Frequently Asked Questions About EMF Radiation and Cancer

Does EMF radiation really cause cancer?

A 2025 WHO-backed study found high-certainty evidence linking EMF radiation from devices like cell phones and wireless earbuds to two types of cancer: gliomas of the brain and schwannomas of the heart. Additional moderate-certainty evidence also linked radiation to adrenal, liver, and lymphatic tumors.

Why should I be concerned about tech radiation now?

Much like how we once underestimated the health risks of cigarettes, tech radiation is now raising red flags. As our daily tech usage increases, so does our exposure to EMF radiation — often at close range to vital organs.

How does EMF radiation impact the human body?

EMF radiation can create oxidative stress and DNA damage, both markers for cancer development. It may also disrupt hormonal balance, sleep patterns, and cell regulation — all critical for long-term health and cancer prevention.

What devices emit EMF radiation?

Common tech like cell phones, laptops, tablets, WiFi routers, wireless earbuds, and hotspots emit EMF radiation. These are devices most families use daily.

How can WaveBlock® help reduce my family’s exposure?

WaveBlock® offers patented, lab-tested EMF-blocking stickers for cell phones, earbuds, laptops, and tablets. These products are simple to use and backed by science to reduce EMF exposure without affecting device performance.

What’s different about the 2025 WHO study?

This is one of the most comprehensive animal studies to date, commissioned by the WHO and published in a peer-reviewed journal. It strengthens the evidence linking EMF exposure to cancer, increasing pressure to update safety regulations.
