Prostate cancer grows and spreads slowly therefore symptoms are likely to appear in the advanced or metastatic stage of cancer. Early diagnosis of prostate cancer can prevent it from spreading to the nearby organs and for this purpose biopsies are done.
The procedure involves a rectal insertion of an ultrasound probe to get a clear image of the prostate gland. By means of a spring-loaded tool, the doctor collects several samples from different areas of the prostate. Through prostate biopsy, the doctor successfully collects about 10-12 core samples, 5-6 from the either sides. If in certain cases the doctor requires the collection of larger samples, he may perform saturation biopsy which yields up to 20-30 samples. The procedure lasts for about 20 minutes after which the doctor may recommend antibiotics to the patient in order to minimize the risk of infection.
The doctor may also perform trans-perineal biopsy in which a small cut is made between the scrotum and the anus. The needle is inserted through this cut into the prostate for the extraction of sample tissue.

After the biopsy is successfully performed, the results along with other influencing factors will let the doctor determine how aggressive the cancer is and what will be the most appropriate treatment approach. Therefore, it is safe to say that the outlook usually depends upon the biopsy results. Factors that may affect the outlook include:
