The purpose of the Danish colorectal cancer screening programme is to detect cancer in the colon or rectum at an early or preliminary stage. Early detection is an advantage as it allows for a milder treatment and a higher possibility of cure and sometimes even treatment before the condition turns into cancer.

All men and women aged 50 to 74 years are invited to participate in screening for colorectal cancer every second year. Screening is performed by examining the faeces for blood. You collect a small sample of faeces at home using a self-sampling kit and send the sample to a laboratory for analysis.

If blood is found in the faeces, you are offered further examination using colonoscopy. Colonoscopy is a visual inspection of the interior of the colon with a flexible tube inserted through the rectum. The occurrence of blood in the faeces can be caused by several things other than colorectal cancer. The colonoscopy will determine the cause.

It is important to note that you should contact your general practitioner if you experience symptoms such as blood or mucus in your faeces or changed or abnormal bowel function, even if you participate in colorectal cancer screening.

If you have any further questions regarding colorectal cancer screening, please contact your general practitioner or the Department of Public Health Programmes:
