Key Points

• According to available data, the number of invitations sent appears to be comparable to previous periods.

• The participation rate among the target population is 30.7%, a slight increase from the previous period (29.6% in 2023–2024) and still below the acceptable European threshold (45%).

• For 2025 alone, the participation rate among the target population is 33.1%; it was 30.8% in 2023 (comparison year*) and 28.4% in 2024.

• The participation rate among the eligible population cannot be calculated in the absence of aggregated data on individuals excluded from the PNDOCCR.

• The proportion of people with an unanalyzed screening test that was not retaken is 2.8% (below the European benchmark of 3%), but nevertheless warrants monitoring in Corsica, in the DROMs, and for those aged 70–74 at the national level.

• The proportion of people with a positive screening test is 3.4%, a figure that has remained stable in recent years.

• There has been an increase in the proportion of kits sent to homes with the second reminder (16.4% of all kits received in 2025).
