Answer to Question 1
ANS: D
It is anticipated that over 2,000 new cases of male breast cancer will be diagnosed in 2013, with over 400 related deaths (ACS 2013). Men develop the same types of breast cancer as women. Therefore, it is important to include malignancy in the differential diagnosis when a man complains of breast enlargement. Factors that increase the risk of breast cancer in men include a previous history of breast or testicular disease and Klinefelter's syndrome. A history of gynecomastia is not associated with an increased risk for breast cancer.
