Colorectal cancer screening

The aim of colorectal cancer screening is to detect potential precancerous changes at an early stage.

In colorectal cancer screening, hidden blood in stool is tested. Individuals invited to screening receive a letter package at their home address, which includes an invitation letter, sampling equipment, and detailed instructions for collecting the sample.

Eligible age groups are invited to free screening every two years. The screening will gradually expand to include all individuals aged 56–74 starting from 2032. Legislation requires wellbeing services counties to organize colorectal cancer screening for their residents.
