Prolific documentary filmmaker Ken Burns is turning his lens on cancer for his next project “The Story of Cancer,” premiering on PBS in the spring.

The three-part, six-hour series includes testimonials from celebrities like Maura Tierney, who shares her fight against breast cancer in this exclusive video.

Tierney — who is currently starring in Showtime’s new drama “The Affair” — describes her fear sitting in the waiting room for her results as “like the worst audition ever.” She also talks about being more afraid of chemotherapy than cancer, going bald and having to wear a wig, and the individuals who helped show her cancer doesn’t have to be so scary.

“The Story of Cancer: The Emperor of All Maladies” includes three different films — a historical documentary; an intimate vérité film; and a scientific and investigative report that seeks to strip away some of the fear and misunderstanding that surrounds the disease.
