 Hello, I'm Marissa Jarrett-Winokur. Performing on stage takes mental and physical preparation. But one thing I never thought to prepare for was cervical cancer. 91% of cervical cancers are caused by the human papillomavirus, or HPV. One in every four Americans is infected with HPV. For many people, the virus hides inside them, and they never develop symptoms. But for others, HPV links directly to them.
