Questiоns 36 – 40. Suppоse thаt 50,000 wоmen who hаve never hаd a breast cancer diagnosis are available and willing to participate in a new screening program of computerized digital mammography. 1132 women had a positive screening test. All of these positive women had a breast biopsy and 136 were diagnosed with breast cancer. Of the 48,868 who screened “negative” on the test, 24 were in fact in the detectable pre-clinical phase.
