Discussion Part One (graded)
Shelby is a 32-year-old mother of two, who has smoked 1
pack-per-day for the last 15 years, and who comes to see you today for her
yearly well-woman exam in your family practice clinic. She has a family
history, in a single paternal grandmother of breast cancer at age 52. She also
has a history of an abnormal cervical cancer screening three years ago
requiring colposcopy.
Given her history please consider the following:
Choose one screening test that might be considered either
now or in the next few years of Shelby’s care. Define the test, its positive
predictive value, reliability and validity.
