Pregnancy, leading to new life, on one hand, and life threatening malignancies an the other hand, are per se diametric subjects. Symptoms of malignancies are ignored more frequently during pregnancy by patients and physicians, often resulting in delayed diagnosis. Diagnosis and treatment of gynaecological malignancies, however, are increasingly important for four reasons: the peak incidence of several malignancies occurs during the reproductive age; late pregnancies present more often in an age group with increased risk for cancer, intensified care for pregnant women leads to more thorough diagnosis, and, curative treatment of malignancies gives women the potential chance for becoming pregnant. For these reasons, special features of the diagnosis and treatment of gynaecological malignancies will regularly part of routine patient care.
