Cellular Phone Use and Risk of Tumors: Systematic Review and Meta-Analysis

Safer Technology Aotearoa New Zealand

Abstract: We investigated whether cellular phone use was associated with increased risk of tumors using a meta-analysis of case-control studies. PubMed and EMBASE were searched from inception to July 2018. The primary outcome was the risk of tumors by cellular phone use, which was measured by pooling each odds ratio (OR) and its 95% confidence interval (CI). In a meta-analysis of 46 case-control studies, compared with never or rarely having used a cellular phone, regular use was not associated with tumor risk in the random-effects meta-analysis. However, in the subgroup meta-analysis by research group, there was a statistically significant positive association (harmful effect) in the Hardell et al. studies (OR, 1.15—95% CI, 1.00 to 1.33— n = 10), a statistically significant negative association (beneficial effect) in the INTERPHONE-related studies (case-control studies from 13 countries coordinated by the International Agency for Research on Cancer (IARC); (OR, 0.81—95% CI, 0.75 to 0.89—n = 9), and no statistically significant association in other research groups’ studies. Further, cellular phone use with cumulative call time more than 1000 hours statistically significantly increased the risk of tumors. This comprehensive meta-analysis of case-control studies found evidence that linked cellular phone use to increased tumor risk.

European Parliament: 5G Health Effects and Environmental Impacts

Over the last decades, novel wireless communication technologies, such as mobile telephones, cellular networks and Wi-Fi, have been developed at unparalleled speed. However, 5G, along with 3G and 4G, may also pose threats to human health and the environment. This article outlines the two STOA studies presented to the EU Parliament, which take stock of our present understanding of the impacts of 5G on health and the environment.

All over the world, scientists, governments, corporations and consumers are collaborating to turn the Earth into a giant computer, fulfilling the warning predictions of the great Swedish physicist and Nobel laureate Hannes Alfvén. Written under the pen name Olof Johannesson, his 1966 science fiction novel Sagan om den stora datamaskinen (The Tale of the Great Computer) predicted smart phones, the internet, fitbits, artificial intelligence, chip implants enabling direct human-to-computer communication, the colonization of Mars, and ultimately the replacement of humankind entirely by computers, which regarded human beings as just one step on the evolutionary path to themselves.
