Sure. A Danish cohort study with almost 360,000 people found no statistical correlation between cell phone usage and tumors: http://www.bmj.com/content/343/bmj.d6387 http://www.bmj.com/content/343/bmj.d6387 A UK prospective study of 1 million women had similar results: https://academic.oup.com/ije/article/42/3/792/2901734 https://academic.oup.com/ije/article/42/3/792/2901734 Another study spanning 13 countries found some correlation with the highest use cases, but was cautiously worded that the effects may not be causative: https://www.ncbi.nlm.nih.gov/pubmed/20483835 https://www.ncbi.nlm.nih.gov/pubmed/20483835 An Australian study similarly found no increase in brain cancer rates over its 30-year study period: https://theconversation.com/new-study-no-increase-in-brain-cancer-across-29-years-of-mobile-use-in-australia-58927 https://theconversation.com/new-study-no-increase-in-brain-c... (sorry, can't get the original source for this one -- had to dig it out of Google from memory). A US population study from 1992 to 2008 found that incidence rates of glioma remained steady throughout that period: http://www.bmj.com/content/344/bmj.e1147 http://www.bmj.com/content/344/bmj.e1147 The CDC has a cool dataviz tool that compiles a bunch of data from 1999 to 2014 (the most recent year for which it's available): https://gis.cdc.gov/grasp/USCS/DataViz.html https://gis.cdc.gov/grasp/USCS/DataViz.html (click on the "Trends" button near the top). The trend line for annual rates for all new cancers for that period is flat; brain cancers are flat too, although thyroid cancers increase over that period at an unsettling rate. The articles I can find on that suggest that some (though maybe not all) of that increase is due to changes in diagnostic techniques, e.g. https://www.medscape.com/viewarticle/878030 https://www.medscape.com/viewarticle/878030 There have been studies with rodents that did find statistically significant increases, but -- as far as I know -- those have all had some pretty serious methodological issues, like unrealistically massive amounts of exposure or not controlling for the tissue temperature increases that can be caused by exposure to powerful microwave radiation. All of the big human population studies that I know of have found either no correlation at all, or some correlation but at such small numbers that it could also be statistical noise. If any large studies have found conclusive statistical correlation in humans between cell phones and cancer, I'm not aware of it. (And would like to be.) edit: which is not to say btw that cell phones aren't dangerous. They kill people every year -- just not with cancer, but by being a distraction while driving. http://www.nsc.org/learn/NSC-Initiatives/Pages/priorities-cell-phone-crash-data.aspx http://www.nsc.org/learn/NSC-Initiatives/Pages/priorities-ce... . "A Deadly Wandering" is also a pretty okay book about this. Multiple studies described in that book found that, with very very rare exception, people could not safely drive and operate a cell phone at the same time, no matter how good they thought they were at multi-tasking. This is my PSA for the day.
