While the use of cellphones cannot definitively be linked to brain cancer, many studies that have suggested this have gone under society’s radar, report Mark Hertsgaard and Mark Dowie of The Week. The mobile phone industry has selectively funded studies and scientists in order to get results that would benefit it. When links between phones and cancer were published, industry-backed scientists would often dispute these claims, say Hertsgaard and Dowie. Particularly worrying is the impending introduction of 5G, which will increase the radiation levels humans will be exposed to. More studies need to examine the full danger of our cellphones.
The assertion that cellphones cause brain cancer cannot be believed as it hasn’t been proven, asserts Matt Simon of Wired. While the radio waves they emit are a form of radiation, it is so low that it’s far from dangerous. One much-cited study alleging phones’ link to cancer was done on mice. They are genetically different from humans as were exposed to up to seven times the radiation a cellphone emits. No study has been able to definitively prove this connection. Brain tumor rates are steady over the past 40 years. The UN says phones possibly cause cancer, but before that claim can be made outright, more proof is needed.
