Ovarian Cancer
Definition
The term ovarian cancer is used to describe a heterogeneous group of malignant tumors found in the ovary (there is also a wide assortment of benign tumors derived from the ovary). Ovarian cancer is the most lethal gynecological cancer in industrialized countries and is the sixth leading cause of cancer deaths in women worldwide. Ovarian cancer typically occurs in peri- and postmenopausal women, with an average of 54 years at diagnosis. Histologically, ovarian cancer is complex but can be broadly divided into epithelial ovarian cancer, which accounts for up to 90 % of all the ovarian malignancies, and non-epithelial tumors (sex-cord stromal tumors and ovarian germ cell tumors). Epithelial ovarian tumors have been assumed to be derived from the ovarian surface epithelium, but new evidence suggests that some of these tumors may actually originate from extraovarian tissues, such as the fallopian tube epithelium and endometrial tissue.
