Training activities by the Finnish Cancer Registry The director of statistics at the Finnish Cancer Registry was invited to a fixed-term, part-time professorship in cancer epidemiology at the University of Tampere, a position that was previously held by the director of the registry. The director of research at the Cancer Registry had a fixed-term, part-time professorship in epidemiology in the same faculty. Many of the employees of the Cancer Registry work at various universities as docents and are involved in university teaching and in supervising doctoral theses and advanced work and master’s theses. In addition, the researchers work as scientific experts, for instance as peer reviewers for journals in the field. The Cancer Registry participated in the teaching and guidance of foreign students at the University of Tampere’s International Doctoral Programme in Epidemiology. It also partici-pated in the teaching organised by the Faculty of Medicine at the University of Helsinki, which aims to familiarise young researchers and future medical doctors with epidemiological cancer research. The Cancer Registry also plays an important role in the training programme of the Nordic Summer School in Cancer Epidemiology, which has similar goals and for which five students from each of the Nordic countries are selected every two years.
