Images are taken to identify the tumor, locate the urethra, the apex, and the base of the prostate. Although this test is expensive, it can detect tumors as small as 5 mm in diameter. This is not an initial screening tool, rather it is used to diagnose and stage prostate cancer. TRUS is also used to guide the physician to the prostate during a biopsy. In the event of a positive biopsy, the physician will grade and stage the tumor.
Tumor grading indicates how quickly the tumor is growing.
Tumor staging indicates the extent of the tumor and estimates the size and location of the tumor. This is an official FGCU web page.
