Long-term risk of cancer among the first-degree relatives of epithelial ovarian cancer patients: A cohort study with 48 years of follow up.

In our study cohort, we did not observe an increase in the overall cancer risk among the first-degree relatives of epithelial ovarian cancer patients in comparison with the general population. The risk for ovarian cancer, however, was increased. Current recommendations suggest prophylactic removal of the fallopian tubes and ovaries only with identified inherited risk factors. Our results emphasize the role of genetic counselling and testing, particularly in young ovarian cancer patients and their close female relatives.
