Re: Cancer causes cellphones
The xkcd data compares overall cancer rates in the USA, not brain tumors specifically. Clearly there is a major increasing trend in the detection of all cancers in the USA that predates widescale use of mobile phones.
If all of the increase in brain tumors in the UK study was due to people living longer, then all the increase should be in the uppermost age groups - the tumor incidence in younger age groups should be the same as in 1995. We don't have the data here, but the wording of the Telegraph article implies the increase in brain tumors specifically affects the young.
Again, all this relates to existing mobile phone standards 1G-4G which use a different frequency band from 5G, so is incidental to the argument against 5G.
