Of cancers that affect both men and women, colorectal cancer is the second leading cancer killer in the United States, but it doesn't have to be. Colorectal cancer screeningColorectal cancer screening saves lives. Screening can find precancerous polyps—abnormal growths in the colon or rectum—so that they can be removed before turning into cancer. Screening also helps find colorectal cancer at an early stage, when treatment often leads to a cure. About nine out of every 10 people whose colorectal cancers are found early and treated appropriately are still alive five years later.
While screening rates have increased in the U.S., not enough people are getting screened for colorectal cancer—
- As of 2008, 62.9% of adults aged 50–75 years were screened as recommended. In 2002, only 51.9% of Americans were screened as recommended.
- While screening rates continue to rise in the U.S., 22 million people are still not up-to-date with colorectal cancer screening.
