  1. E) would have been a great option these days but I would have also preferred that C)losing wait and D) cessation of smoking would also have assisted in her aim. Though Cessation of smoking also needs for the Withdrawal Symptoms to be controlled, that might be secondary.


  2. The correct answer is C. This patient presumably has endometrial carcinoma. Among the listed choices, obesity is the most significant risk factor for endometrial carcinoma. The proposed mechanism of this risk is thought to be the increased conversion of androgens to estrogens in obese individuals. Women who are overweight are twice as likely to get endometrial cancer than are women who maintain a healthy weight; women who are obese are more than three times as likely to get endometrial cancer.

    A is not correct. Nulliparity would have increased her risk for endometrial cancer.

    B is not correct. Late menopause, or more specifically a woman’s total number of menstrual cycles, is a significant risk factor for endometrial carcinoma because of increased exposure to estrogen. Thus, early menarche or late menopause increase this risk; however, this risk is less significant than that related to obesity.

    D is not correct. There is no known association between smoking and endometrial carcinoma.

    E is not correct. Genetic counseling would not play a role in this patient’s cancer, especially as there is no family history of cancer.
