a 35-year-old white female presents to the office due to a self-palpated breast mass. After the appropriate work-up, fine-needle aspiration (FNA) of the mass is performed. The results of the FNA return as negative. As you are explaining the test results, the patient ask," what is the chances that I really do not have breast cancer?" you reply that the probability of breast cancer is low in her case because FNA has a high:
A. Sensitivity
B. Specificity
C. Positive predictive value
D. Negative predictive value
E. Validity
