Films for the Humanities & Sciences <www.films.com> has a title, "Prostate Cancer" listed in their catalog for $129 with public performance rights. They do sell some titles for home use at a different price, but you did not say which version you needed. I have not seen it, but Films always gets their stuff from reputable sources and I would not hesitate to buy from them. I would check to copyright date, though, sometimes their titles are a little old and there may be something more recent out there.
