Same thing for "oh, but HRT is experimental" (and similar things). It actually predates many well-accepted medical therapies & processes, some by decades.

Fun fact, I did a cursory look on Wikipedia to remind myself, and it looks like it came about in the exact same year as chemotherapy. Which I find a rather amusing coincidence, considering one of the two is definitely well-accepted --- and yet, very damaging with its side-effects (though alas, very necessary ... cancer sucks).

(small nitpick, because my brain just won't let it slide: it's "I'm on a roll", not "role")
