Colorectal cancer screening

Colorectal cancer means cancers of the colon and the rectum. It is the third most common cancer in Finland: over 3,000 people are diagnosed with colorectal cancer every year. The new colorectal cancer screening programme started in Finland in April 2019.

4b.

There is blood in the sample. If the sample contains blood, the letter will provide instructions on how to contact the screening nurse of your home municipality to determine the cause of the blood.

Approximately four out of every 100 people have a positive test result, which means that the stool contains hidden blood. It usually does not mean cancer, but the cause of the blood must be determined.

5.

Colonoscopy Usually the cause of the bleeding is determined by colonoscopy.

The examination unit (health centre or hospital) provides you with detailed instructions on colonoscopy. Colonoscopy is performed with a flexible tube. During the examination the doctor can take biopsies and remove small tumours.

Surgical treatment If cancer is diagnosed in the follow-up examinations, you will receive necessary treatments.
