Fig. 2: Outcome over the study period of detected RCC according to tumour size (maximum diameter in cm).

No intervention = tumour remained under surveillance; very early intvn= proceeded to intervention (surgical removal or ablative procedure) within 12 months; early intervention = proceeded to intervention within 12–35 months of detection; delayed intervention = proceeded to intervention between ≥3 and <5 years of detection; late intervention = proceeded to intervention between ≥5 and <10 years of detection; very late intervention = proceeded to intervention ≥10 years after detection.
