7 Serous 40 percent of all ovarian cancers; most common ovarian cancer Endometrioid 20 percent of all ovarian cancers; 15 percent of endometrioid carcinomas coexist with endometriosis; 40 percent bilateral Mucinous 25 percent of all ovarian cancers; origin unclear; may occur in association with endometriosis; associated with pseudomyxoma peritonei

8 Main factors associated with ovarian cancer risk Increased risk Early menarche/late menopause Endometriosis Estrogen replacement therapy Family history Genetic syndromes High-fat diet Low parity Decreased risk Early menopause/late menarche Multiparity Hysterectomy Low-fat diet Oral contraceptive use
