Pis A 24-year-old female insists of having a screening mammogram. Upon further questioning, the nurse practitioner discovers the patient is concerned about breast cancer because her mother has fibrocystic breast disease. The nurse practitioner would be accurate if she tells the patient that the major risk factor for development of breast cancer in women is:
O Benign breast disease in a first degree relative
O Late menarche (after age 15 years)
O First full-term pregnancy after age 30 years
O Early menopause (before age 45 years)
