Use the following information to answer Questions 4 through Question 8. Suppose that 30,000 women who have never had a breast cancer diagnosis are available and willing to participate in a new screening program of computerized digital mammography. Of that total, 926 women had a positive screening test. All these positive women had a breast biopsy, and 108 were diagnosed with breast cancer. Of the 29,074 who screened “negative” on the test, 22 were, in fact, in the detectable pre-clinical phase. This was determined by following these women and observing that all 22 were diagnosed with breast cancer within 1 year of the screening test. What is the prevalence of the detectable pre-clinical phase of breast cancer in this population?
