Blue March: Colorectal cancer screening – a simple step that can save lives

On the occasion of Blue March, Colorectal Cancer Awareness Month, the Health Directorate wishes to remind the public of the importance of early detection of this disease, which is one of the most common forms of cancer in Luxembourg.

Approximately 300 new cases of colorectal cancer are diagnosed in the country each year. This cancer affects both women and men and remains one of the leading causes of cancer-related death, even though it can often be prevented or detected at an early stage. When detected at an early stage, colorectal cancer can be treated more effectively, thereby improving survival rates and reducing the need for intensive treatment.

The organised colorectal cancer screening programme (PDOCCR)

The organised colorectal cancer screening programme is aimed at women and men aged 45 to 74 who are affiliated with the National Health Fund (CNS), whether or not they reside in Luxembourg. Eligible individuals receive an invitation to participate in the screening every two years. Non-residents affiliated with the CNS may also take part by contacting the Coordination Centre for Cancer Screening Programmes.

Screening is based on a faecal immunochemical test (FIT), which detects occult blood in the stool. The test is simple to use and can be carried out at home. It requires no prior preparation and involves no specific dietary restrictions. The screening kit can be obtained free of charge online via Guichet.lu, by telephone from the Bionext laboratory, at pharmacies, or is sent automatically to individuals who have previously participated in the programme. Once completed, the test can be returned by post or deposited at an approved sample collection centre. Results are communicated directly by the laboratory. In the event of a positive result, individuals are advised to consult their general practitioner, who may recommend a diagnostic colonoscopy if necessary.

Participation rate

In 2025, 91,350 people were invited to participate in the programme, and 31,725 completed the test. Of these tests, 30,259 were negative and 1,466 were positive, requiring further investigations such as a colonoscopy to confirm or rule out the presence of cancer or precancerous lesions.

These figures show that many people respond positively to the screening invitation, but they also indicate that a significant proportion of the target population still needs to be reached in order to achieve broader coverage. Colorectal cancer is common and develops slowly, often without pain or digestive symptoms. It typically arises from lesions known as polyps, which may bleed into the intestine. Bleeding caused by a polyp or a cancer is not visible to the naked eye, which underlines the importance of testing.

“Colorectal cancer screening is a simple, quick and accessible action that can truly save lives. If you have any questions, do not hesitate to contact your trusted doctor for further information,” stated Martine Deprez, Minister for Health and Social Security.
