"I didn't realize Farrah Fawcett had died of anal cancer. There were references to her ailment as cancer "below the colon." It was like my mother, when I was a kid, calling the vagina "your bottom in front." Up through 2010, anal cancer had no nonprofit society, no one to organize fund-raisers and outreach, no colored awareness ribbon. (Even appendix cancer has a ribbon.)* Like cervical cancer, anal cancer is caused by the human papillomavirus; people get it via sex with an infected person, and that seems like something they ought to know when making decisions about using a condom."
