EMF/RF/5G: Mobile Phones and the Thyroid

Courtesy EMR Australia with Patricia Burke

Originally published here.

Could mobile phone radiation affect the thyroid gland, situated as it is on the neck and close to the position where the phone is held?

To answer this question, researchers in the US conducted a review of relevant studies published after 2001.

They found that mobile phone radiation could be linked with hypothyroidism (an underactive thyroid) and changes to thyroid hormone levels. They also found changes in thyroid gland follicles in the thyroids of exposed rats. The more exposure and the longer the exposure, the greater were the effects.

The thyroid gland is part of the endocrine system and its hormones regulate important body functions such as breathing, heart rate, the nervous systems, weight, muscle strength, menstrual cycles, body temperature and cholesterol.

Effects on the thyroid gland could, therefore, have wide-ranging effects on the body.

Among these effects could be thyroid cancer.

A previous study examined rates of thyroid cancers in all Nordic countries from 1970 to 2017. The authors found that the steepest increases occurred between 2001 and 2017, the period during which mobile phones have been widely used.

‘We postulate that RF radiation is a causative factor for the increasing thyroid cancer incidence,’ they concluded.

Cureus. 2021 Aug 20;13(8):e17329. doi: 10.7759/cureus.17329. PMID: 34567874; PMCID: PMC8451508. https://pubmed.ncbi.nlm.nih.gov/34567874/


The use of mobile phones has widely increased over the last two decades. Mobile phones produce a radiofrequency electromagnetic field (RF-EMF), a form of non-ionizing radiation. In contrast to the ionizing radiation proven to cause DNA damage, the harmful effects of non-ionizing radiation on the human body have not been discovered yet. The thyroid gland is among the most susceptible organs to mobile phone radiation due to its location in the anterior neck. Our purpose in this literature review is to explore the effects of the electromagnetic field (EMF), especially radiofrequency emitted from mobile phones, on thyroid hormones and thyroid gland histopathology. We searched PubMed and Google Scholar databases for relevant studies published after the year 2000, using the following keywords: ‘cell phones’, ‘mobile phones’, ‘telephones’, ‘electromagnetic fields’, ‘radiofrequency radiation’, ‘microwaves’, ‘thyroid gland’, ‘thyroid hormones’, and ‘thyroid cancer’. Our review revealed that mobile phone radiofrequency radiation (RFR) might be associated with thyroid gland insufficiency and alterations in serum thyroid hormone levels, with a possible disruption in the hypothalamic-pituitary-thyroid axis. The review also showed histopathological changes in the thyroid gland follicles after exposure of rats to non-ionizing radiation. The results were directly related to the amount and duration of exposure to EMF radiation. Further human studies exploring thyroid gland hormones, microscopic morphology, and thyroid cancer are highly recommended for future researches.

The International Agency for Research on Cancer (IARC) at the World Health Organization (WHO) categorized in 2011 radiofrequency (RF) as a possible human carcinogen, Group 2B. During use of the handheld wireless phone, especially the smartphone, the thyroid gland is a target organ. During the 21st century, the incidence of thyroid cancer is increasing in many countries. We used the Swedish Cancer Register to study trends from 1970 to 2017. During that time period, the incidence increased statistically significantly in women with average annual percentage change (AAPC) +2.13%, 95% confidence interval (CI) +1.43, +2.83%. The increase was especially pronounced during 2010–2017 with annual percentage change (APC) +9.65%, 95% CI +6.68, +12.71%. In men, AAPC increased during 1970–2017 with +1.49%, 95% CI +0.71, +2.28%. Highest increase was found for the time period 2001–2017 with APC +5.26%, 95% CI +4.05, +6.49%. Similar results were found for all Nordic countries based on NORDCAN 1970–2016 with APC +5.83%, 95% CI +4.56, +7.12 in women from 2006 to 2016 and APC + 5.48%, 95% CI +3.92, +7.06% in men from 2005 to 2016. According to the Swedish Cancer Register, the increasing incidence was similar for tumors ≤4 cm as for tumors >4 cm, indicating that the increase cannot be explained by overdiagnosis. These results are in agreement with recent results on increased thyroid cancer risk associated with the use of mobile phones. We postulate that RF radiation is a causative factor for the increasing thyroid cancer incidence. View Full-Text
