A 55 yr old man visits his physician for urinary complaints, who finds a 1cm nodule on his prostate gland and orders PSA test. PSY > than 4ng/ml is considered abnormal by common standards. The test's sensitivity is 80%, specificity 90%. It's found that 10% of men of his age have prostate cancer on a cross sectional study. The patient's PSA is 7ng/ml. What is ur best estimate of the likelihood that this man has prostate cancer?
