The nurse has educated a community group on risk factors for ovarian cancer. Which statement by a participant shows the need for further teaching?

Choice A rationale This statement is incorrect because the risk for developing ovarian cancer actually increases with age, with the majority of cases occurring in women over the age of 50, particularly after menopause. This indicates a need for further teaching. Factors such as lifelong exposure to estrogen and certain genetic mutations become more significant risks as a woman ages past 50. Choice B rationale This statement is correct. Never being pregnant (nulliparity) is a recognized risk factor for ovarian cancer. Each full-term pregnancy and breastfeeding period reduces the lifetime risk by interrupting the constant ovulation cycle, which is theorized to decrease the frequency of epithelial cell damage and subsequent abnormal cell growth. Choice C rationale This statement is correct. Difficulty conceiving or infertility is a known risk factor, potentially because the underlying hormonal imbalances or treatments (like fertility drugs) associated with infertility may also contribute to the development of ovarian cancer by increasing lifetime exposure to reproductive hormones or disrupting normal ovarian function. Choice D rationale This statement is correct. Endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus, is a risk factor. There is evidence suggesting that long-standing irritation and inflammation from endometriosis can increase the risk of certain types of epithelial ovarian cancers, specifically endometrioid and clear cell subtypes.
