Final answer:
Sarah's initial Pap smear result detecting evidence of cervical cancer is a false positive.
Step-by-step explanation:
Sarah's initial Pap smear result detected evidence of cervical cancer, but further diagnostic testing indicated that she did not have cancer. This is an example of a false positive result. A false positive result occurs when a screening test shows that a person has a condition or disease when they do not actually have it. In this case, the initial Pap smear result indicated cancer, but the follow-up testing showed that there was no cancer present.
