Diagnosis & Biopsy
Abnormal screening results may indicate that further testing is needed. A diagnosis of prostate cancer is achieved through an ultrasound-guided biopsy of the prostate gland. A prostate biopsy is conducted with a transrectal ultrasound and biopsy needle to collect small slivers of prostate tissue that are analyzed for cancer. This tissue is then examined under a microscope for cancer cells. A biopsy of the prostate can be performed in the physician’s office and patients usually return home the same day. Keep in mind that it is still possible to have cancer, even if the biopsy is negative, because the cancer cells may not have progressed enough to be detected by a microscope or the biopsy may miss the areas of cancer within the prostate.
