One of the most deadly killers among the cancers. And quick, too. Took Michael Landon, Jack Benny, Fred Gwynn, Bill Bixby, Donna Reed, and Patrick Swayze. among others. Just before he died, Landon appeared on Johnny Carson and joked that by the time you learned how to say its medical name (ductal adenocarcinoma), you were already dead.
I remember Landon talking about coffee enemas.
