I'll go farther back to the time when Candace Bergen (you know, Murphy Brown) launched a very short-lived career as a magazine writer at the start of Second Wave Feminism, around 1969. She wrote an article for either Esquire or Playboy about women's roller hockey in which she claimed that many fanatic competitors have their right breasts removed to as to improve their swing at hitting the puck. None of this info made it into her Wikipedia page.
