If an abnormality is detected on a DRE or PSA test, your doctor may recommend tests to determine if you have prostate cancer, such as an ultrasound and a prostate biopsy.
- Ultrasound. If other tests raise concerns, your doctor may use transrectal ultrasound to further evaluate your prostate. A small probe, about the size and shape of a cigar, is inserted into your rectum. The probe uses sound waves to make a picture of your prostate gland.
- Collecting a sample of prostate tissue. If initial test results suggest prostate cancer, your doctor may recommend a procedure to collect a sample of cells from your prostate (prostate biopsy). Prostate biopsy is often performed by inserting a thin needle into the prostate to collect tissue. The tissue sample is analyzed in a lab to determine presence or absence of cancer cells.
