Prostate Biopsy

What is a prostate biopsy?

Prostate biopsy guided with the traditional Trans-Rectal Ultra Sound method (TRUS Prostate Biopsy) is a prostate cancer diagnostic method that is typically used for men with a raised PSA (prostate specific antigen). Statistically, you have a 1 in 4 chance of having prostate cancer if you have raised PSA.

How is a prostate biopsy taken?

Prostate biopsies performed in the standard way use an ultrasound scanning probe in the back passage. A biopsy needle passes through the lining of the back passage to take various samples of the prostate tissue. Generally you will have between 6 and 14 samples taken throughout the prostate in a random fashion when you have a prostate biopsy.

What will a prostate biopsy tell me?

After a biopsy of the prostate, you will be informed of how many prostate biopsies were taken, whether there is cancer in any of the biopsies, how much cancer is there in each biopsy, and how aggressive the prostate cancer might be.

What are the limitations of traditional prostate biopsies?

Traditional prostate biopsies can give negative results in up to 20% of men who actually have cancer because they miss large areas of the prostate. Also, a prostate biopsy can wrongly report how aggressive the prostate cancer may be. Typically 20% of men have more aggressive cancer than initially detected by traditional prostate biopsy. And over 50% of men have more areas of cancer than detected by prostate biopsy.
