Ovarian cancer is the most lethal disease among all gynaecological malignancies. It can be categorized into three major groups according to the origins of the ovarian tumors: (1) epithelial tumors, (2) stromal tumors and (3) germ cell tumors. Among these three groups, Epithelial Ovarian Cancer (EOC) accounts for approximately 90% of ovarian malignancies and can be divided into four major histological subtypes based on morphological and appearance criteria: serous, mucinous, endometrioid and clear cell carcinoma. Each of these histologic subtypes is further subdivided into benign, borderline and malignant according to their malignant potential.
