For decades, people have made claims that radiation from cell phones could be harmful to human health, citing concerns about potential neurological damage and cancer. Secretary of Health and Human Services Robert F. Kennedy Jr. has been vocal about these views, noting that about two dozen states have limited cell phone use in schools to improve children’s mental and physical health. However, medical experts emphasize that while cell phones do emit radiofrequency radiation, there is no solid scientific evidence supporting significant health risks from this type of exposure.
Radiation and Cancer Risk
Cell phones emit radiofrequency radiation, a type of low-energy radiation found in many household devices including TVs, microwave ovens, computers, and Wi-Fi routers. The concern stems partly from the fact that people use phones close to their heads. However, the radiation most closely linked to head and neck cancers is ionizing radiation—a higher form of radiation than what cell phones emit. According to Herbert Newton, MD, a neuro-oncologist at University Hospitals in Ohio, ionizing radiation is powerful and shown to damage cell DNA, while cell phones emit a very small dose of radiofrequency radiation over time, with “no solid proof of cancer resulting from these low doses.”
The non-existent link between cell phone use and cancer is backed by years of research. A 2024 World Health Organization-funded study involving nearly 5,000 participants found no connection between cell phone use and increased brain cancer risk, even among people who spent significant time on phones, made many calls, or used phones for 10 years or more. Researchers also found that cell towers did not put people at higher risk.
Other Health Concerns
A 2024 Canadian study suggesting cell phone use elevated cardiovascular disease risk drew cautious responses. The researchers themselves cautioned against overgeneralizing their findings and noted that “more conclusive evidence with valid measurements of mobile phone use is needed before this association becomes a concern for the general public.” Cardiologist Karishama Patwa states: “Current evidence does not support any causation between cell phone radiation and cardiovascular disease. Most research thus far has had limitations and inconsistencies.”
To reduce exposure, experts suggest limiting situations where you hold phones to your ear, opting instead for texting or speakerphone use. Keeping the phone a few feet away provides a much-reduced dose. However, the greater risk Dr. Newton emphasizes is not radiation but phone addiction and excess screen time, which raise risk of eye strain, neck and back pain, and increased depression and anxiety symptoms.
