I hope nobody will be offended by what I am about to say...if so...please
don't take it personally or just hit the delete key.
Many of these alleged "High Tension Studies" appear to suffer from the well
known illogic characterized in Law for hundreds of years as "post hoc ergo
propter hoc"...or..."after the fact therefore on account of the fact"
illogic. You experience this illogic every day by alleged experts, all
politicians, almost every con artist and every day TV advertising. It is
akin to a Jedi mind trick (remember Star Wars?) and works very well...this
is why it is used so often.
An illustration of this is the following example:
"It has been proven by thousands of tests that the beating of tom toms after
an eclipse will restore the sun".
The above appeared on a sign posted on the first cyclotron I saw at the
University of California to remind scientists and grad students to not get
sucked into the illogic demonstrated by others at the time regarding various
ultimately discredited "scientific findings" (this was in the early 60's).
There may be a relationship between 50 Hz and or 60 Hz power line magnetic
fields and/or any other alleged disease (including but not limited to
cancer) but many of these "studies" wont pass the burst of laughter test
when examined for proof of causality other than "post hoc ergo propter hoc"
illogic as in the example of the use of tom tops to restore the sun. :-)

PS Perhaps we should all keep our tom toms handy...they may also work to
protect us from the 50 Hz...or was it the 60Hz alleged evil power line
cancer inducing powers and magic....and pass the Watneys...or was it
Guiness?? (room temperature 807s to you Yanks) :-)

Perhaps somewhere in my collection of clippings I still have the article
I found many years ago in the reputable UK _Wireless World_ publication
(which has since changed its name, I think). I don't recall the author's
name, but he argued that the confusing findings in studies of possible
correlation between proximity to HV lines and the incidence of cancer
was due to the failure to distinguish between 50Hz transmission systems
and those using 60Hz. Somewhere between those frequencies, he argued,
was some crucial turning point in the effect on the human body.
