The division of cancer epidemiology studies the causes of cancer in population groups with the aim of identifying and, if possible, avoiding risk factors so as to prevent cancer. We are identifying and quantifying risks associated with potential cancer-causing substances in the environment and the workplace. Furthermore, we are studying the role of dietary factors and ionizing radiation in cancer development.

We are trying to identify high-risk groups, i.e., individuals who have an increased risk of developing cancer compared to others under the same environmental exposure. Such an individually increased cancer risk can be related to heritable or acquired factors.

A further focus is exploring new routes for prevention and early diagnosis of cancer as well as quality control of introduced measures. Due to the population-related approach, statistical methods and their further development are of a particularly high relevance in epidemiology.
