The number of certified oncologist per capita is highest in Sweden with over 60 per million population and lowest in Korea, Luxembourg and Chile with under three per million. The data need to be interpreted with care as the data coverage and also cancer incidence are different across countries besides variation in practice patterns in oncology. But the data are generally comparable to Eurostat data, which ranges between zero in Luxembourg in 2003 and 50 per million population in the Slovak Republic in 2006.
