Authors' objectives: Colorectal cancer covers cancers in both the colon (colon cancer or bowel cancer) and rectum (rectal cancer). It’s one of the most common cancers in Wales, with about 2,300 new cases in Wales each year. Faecal immunochemical tests can detect small amounts of blood in stool samples. They can help GPs decide if people with unexplained CRC-associated symptoms, but no rectal bleeding, should be referred for more urgent tests. Other characteristics, such as age or gender, can also help GPs identify people who are at risk. HTW has assessed tools that included faecal immunochemical tests and other characteristics, to help NHS Wales decide whether to use these tools.
