Increase in colorectal cancer among young people: the role of smartphones

Increase in colorectal cancer among young people: the role of smartphones
By : Phonegate Team • 10 Oct 2024

A recent study presented by Dr. De-Kun Li at the 35th Annual Conference of the International Society for Environmental Epidemiology in Santiago, Chile, in 2024, suggests a potential link between regularly carrying mobile phones in our pants pockets and the increase in colorectal cancer cases among young adults. This research is part of the broader context of the “Phonegate” scandal, revealed in 2016 in France, concerning the exceeding of electromagnetic wave exposure standards by our mobile phones.

Results of Dr. Li’s study

Dr. Li’s pilot study, designed to examine 50 cases of EOCRC* and 50 matched controls, revealed striking results:

  • People carrying a phone below the waist were four times more likely to develop tumors.
  • The link was particularly strong when the phone was carried on the same side where the tumor developed.
  • Those who carried a phone on the left side for more than 30,000 hours (about 10 years) were 12 times more likely to develop a tumor on that side of the colon.
  • The risk was significantly higher for ipsilateral (same side) carrying than for contralateral (opposite side) carrying.


Dr. Li emphasizes: “The striking contrast between a strong association with ipsilateral carrying and, largely, the absence of a link with contralateral carrying is the most notable finding.”



Divergent opinions in the scientific community

Kurt Straif, former section head at IARC, expresses skepticism towards Dr. Li’s study, describing it as a small study reporting implausible associations with wide confidence intervals. He believes that the current risk factors for colorectal cancer in young people remain plausible, and that the timing of the increase in cases does not correspond to the widespread use of mobile phones among young people.

It should be noted that Straif also works for ISGlobal, an institute which Alerte Phonegate has revealed that funding transits through an industry-supported foundation, which could potentially influence his position on the issue.

However, as reported by Microwave News, Dr. Li defends his results by emphasizing the importance of the striking difference between ipsilateral and contralateral risks, as well as the temporal coincidence between the massive adoption of mobile phones and the increase in colorectal cancer cases among young adults.

Rebecca Siegel of the American Cancer Society also questions Li’s conclusions, particularly regarding the chronology. She points out that rectal cancer rates have been increasing since the 1970s-1980s among 20-30 year olds, well before the massive adoption of mobile phones in the 2000s.

Dr. Li contests these criticisms, arguing that mobile phone use began to take off in the mid-1990s and that the big jump in early-onset colorectal cancer rates occurred later than suggested.

As shown by the trends presented in the JAMA Open (2019) review of EOCRC incidence in Canada for men and women below, with a clear increase starting from the late 1990s and early 2000s.

Implications for future research and public health

These contradictory results, combined with the revelations of Phonegate, underscore the need for mobile phone users to adopt a cautious approach regarding their exposure to waves.

Dr. Marc Arazi, president of the NGO Alerte Phonegate, comments:

“Dr. Li’s study, in the context of Phonegate, reinforces our call to the scientific community and regulatory authorities for an urgent reassessment of radiofrequency exposure standards. It is crucial to explore this potential link more deeply while taking into account other risk factors.”

While awaiting further research, it is recommended that mobile phone users, especially young adults, take precautions to limit their exposure to radiofrequencies. This can be done by using the speakerphone mode or wired headphones and avoiding carrying their phone directly on the body.

Public health must consider all potential risk factors related to new technologies, including those highlighted by Phonegate. Only in this way can we hope to reverse the worrying trend of colorectal cancer cases among young adults and ensure safer use of mobile technologies.
