Lifestyle, Reproduction and Cancer

Group leader: Allan Jensen

The main part of the research in the group falls within two research areas.

One main research area is ovarian cancer epidemiology where we aim to identify risk factors, prognostic factors, gene-environment interactions and build risk prediction models for this highly deadly cancer type.

Another major research interest is to study adverse health effects related to female infertility. By use of data from the large Danish Infertility Cohort, we are studying the associations between infertility, fertility treatment, and the risk of cancer and other morbidity in both women with fertility problems and their children. Further, we are studying the association between male infertility, semen characteristics and cancer.
