Prostate Cancer Study
A 42-year old banker was encouraged to go for a PSA test by his brother who was diagnosed with prostrate cancer at 48.
Results: PSA level: 5.6ng/mL
Digital exam: asymmetrically firm prostrate on the right
Ultrasound: prostate volume of 32 cc; Bone scan: no evidence of metastasis
1. What does PSA stand for? (prostate specific antigen) am i correct?
2. What anatomical structure is in a convenient location for digital examination of the prostrate?
3. What other tests (besides digital exam and PSA screening) should be included in a prostate diagnosis?
4. Why is a bone scan used to test for metastasis in a case like this?
