dq 1

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:

Prevalence

The number of cases of a disease in a given time regardless of when it began. (new and old cases)

(Persons with the disease/ Total population) X 1000

Attributable Risk

The difference in diseasein those exposed and unexposed and is calculated from prospective data. Directly attributed to exposure (if exposure gone, disease would be gone)
