What is a biopsy?

A biopsy is a procedure that removes a sample of tissue or cells for study and are most commonly used to look for cancer.

Prostate biopsies are done with a biopsy needle that can be positioned with the assistance of ultrasound images to get samples for testing.

Your doctor might decide you need a prostate biopsy based on the results of a blood test that measures your level of PSA (prostate-specific antigen). A high PSA result might point to cancer, but there are other things such as non-cancerous enlargement (BPH) or infection that cause PSA to rise. Tests that measure derivatives of PSA (fPSA, -2proPSA, hk2) such as OPKO 4k and Prostate Health Index may be more accurate than PSA in assessing your risk for having a cancer that needs treatment.
