Katie Couric's colonoscopy was important because it helped raised awareness of colon cancer and the importance of undergoing the procedure. After Couric's colonoscopy was aired on live TV in March of 2000, the colonoscopy rates increased by 20 percent in the United States.
Couric's live colonoscopy demonstrated the ease and painlessness of the procedure to the audience. Katie Couric was inspired to undertake the procedure on TV by her husband's 1998 death, which was caused by colon cancer. The live procedure was part of a week-long colon cancer awareness campaign. Katie Couric also founded the Colorectal Cancer Research Alliance after her husband's death.
