The radiation emitted from wireless technology causes tumors and cancers and aggravates existing cancers. Asserting otherwise or suggesting that the “science is unclear” or that “scientists are in dispute” demonstrates either:

  • ignorance of the existing science, or
  • the presence of conflicting interests and artificially manufactured doubt.

There are numerous animal studies proving beyond doubt that this radiation can cause cancer.

In 2016, a $25 million US government study, conducted by the National Toxicology Program (NTP) of the National Institutes of Health (NIH) reported partial findings, which showed that wireless radiation caused two types of tumors:

  • a tumor of the glial cells in the brain
  • malignant schwannoma of the heart (a very rare tumor).

This study also proved that there was “a significant dose-response relationship”. These findings were withheld from the public and scientific communities. With the understanding that these results have alarming implications for public health, the participating scientists acted independently and gave an interview to Microwave News about the study and results.

The study also found that this radiation might also cause damage to DNA and the neurological system. Dr. Joel Moskowitz, director of the Center for Family and Community Health at UC Berkeley’s School of Public Health, published an informative table entitled “Spin vs. Facts” in which he refutes the interest groups’ manipulation of the findings. (For Dr. Moskowitz’s full article about the study, press here.)

Epidemiological studies, including those published by Prof. Lennart Hardell, MD, PhD (a leading scientist on the issue of cell phones and cancer, and a member of IARC, the WHO agency responsible for the classification of carcinogens), as well as the Interphone study (an interview-based case-control study, which was conducted in 13 countries using a common protocol), confirm the physiological findings and indicate an increase in these cancers and tumors in the population and leave no doubt as to a causal relationship between wireless technology — especially cell phones — and cancer.

Causation has been established between cell phone radiation and at least three types of brain tumors:

  • glioma
  • salivary gland neuroma, and
  • acoustic neuroma.

Dr. Lennart Hardell, in a letter written to the Director General of the World Health Organization (WHO), states:

there is consistent evidence of increased risk for glioma and acoustic neuroma associated with use of mobile phones and cordless phones.”

Additional locations for tumors associated with wireless technology radiation include:

  • thyroid
  • breast
  • places that come into contact with the cell phone, such as:
    • regions near pants, shirt or suit pockets
    • the hand
    • other places near where the cell phone was held


Data from the US through 2006 show that the rate of brain tumors associated with cell phone use has doubled for adults. It is reasonable to assume that now, ten years later, it is probably higher.

A study published in Pathophysiology in March 2015 analyzed data from Sweden through 2009. It showed a clear trend of increased risk of brain cancer with longer cell phone use and found the risk to be three times higher for people who used cell phones for 25 years or longer. The rates are higher for children.

Unfortunately, interested parties continue to mislead the public and manipulate the data to claim that there is no increase in brain tumors. An article in Microwave News, a highly respected leader in reporting on the issue of wireless technology radiation, sheds light on the real facts and data.

In Prof. Hardell’s letter to the Director General of the WHO, he explained the increased sensitivity of children, writing:

Children and adolescents are more exposed to RF-EMF than adults due to thinner skull bone, higher conductivity in the brain tissue, and a smaller head. The developing brain is also more vulnerable than in adults and it is still developing until about 20 years of age. The finding of higher risk in young persons is worrying, not the least due to the high prevalence of use of wireless phones in children and adolescents.

His study found that people who started to use cell or cordless phones before the age of 20 have the highest risk of developing glioma. In 2016, a new report published in the journal Neuro-Oncology and funded by the American Brain Tumor Association found that malignant brain tumors are the most common cause of cancer deaths in adolescents and young adults.

There are many cases and lawsuits around the world, but the wireless industry has been settling most of them out of court to avoid publicity.

In 2013, the Italian Supreme Court acknowledged that a cell phone provided by a plaintiff’s employer caused a brain tumor. In the US, there are 29 brain tumor cases in the courts. In a 2015 evidentiary hearing, the Superior Federal Court of the District of Columbia ruled that general causation between brain tumors and cell phones was established, and therefore allowed the cases to move forward.

Since cancer takes a long time to develop, only now — 20 years after cell phones have become popular — are we beginning to see the impact of wireless technology on cancer rates. Also, because causation is difficult to establish, it is difficult to determine the extent of the radiation-related cancers.

However, there are other conditions caused by wireless radiation that seem to have higher incidence, at least in the short term, such as electromagnetic sensitivity and fertility problems. Nevertheless, the interested parties have been focusing the discussion on cancer because it is easier to create doubt regarding the cause.
