Patients often undergo a prostate biopsy in the doctor’s office. A probe is passed through the rectum, and then a needle is used to collect small samples of tissue from the prostate gland. Those tissue samples will be sent for testing, and your doctor will discuss the results with you in a separate visit. The procedure usually takes about 10 to 15 minutes.
Your doctor may choose magnetic resonance imaging (MRI) to determine the presence of cancer cells and to what extent they may have spread. An MRI provides a more detailed picture of the prostate without using radiation. Typically, the procedure involves inserting a thin wire covered with a latex balloon into the rectum. The wire then emits magnetic waves that produce an image that can be viewed on a monitor.
