I’ve been noticing that in many cases of people getting diagnosed with serious fatal brain cancers (Gliomas, especially stage 4), they often have a history of flying a year before or so, in a long flight. The incidence for stage 4 gliomas has been steadily increasing since 1995.

What do you think are to blame here? Cellphones and airplanes seem to be the most common culprits, but I doubt even if there is an increased risk this will be reported as it could topple a massive industry. Much like how companies lied about tobacco not causing cancer until it went into epidemic proportions.
