Journalist and author Katie Couric has interviewed luminaries from all over the world—but the thing that inspires us most is her passionate advocacy for health care screenings.

Way back in 2000, Katie underwent a colonoscopy on national television (the Today show), reporting to millions of viewers that the procedure is painless. Deemed "the Katie Couric effect," colonoscopy rates across the U.S. increased by more than 20%, thanks to this likeable figure bravely sharing her personal experience and the story of losing her husband to colorectal cancer.

Five years later, Katie broadcast her mammogram as part of National Breast Cancer Awareness Month.

Couric also works to raise awareness about Parkinson's Disease, and is a powerful and devoted spokesperson for public health. Let's stay informed together, and on top of those recommended regular screenings!
