A rectal exam often reveals the hard, irregular surface of an enlarged prostate.
Testing considerations:
-
PSA (prostate specific antigen, a blood test) may be elevated, although other conditions such as BPH can cause the PSA to rise.
- Free PSA may be more specific in differentiating BPH from prostate cancer.
-
Urinalysis may reveal blood in the urine.
- Urine or prostatic fluid cytology may reveal atypical cells.
- A prostate biopsy confirms the diagnosis.
- CT scans may be performed to rule out metastasis (spread of the cancer).
- A bone scan may be performed to rule out metastasis.
- Chest x-ray may be performed to rule out metastasis.
A newer test called AMACR is more sensitive for determining the presence of prostate cancer than the PSA test and may soon be more widely used to diagnose disease.
