How a prostate biopsy is done using a TRUS. Doctors can use a TRUS to guide a needle into an abnormal area to collect a sample of cells or tissue. The sample of tissue is then examined under a microscope to check for cancer. The doctor places a needle next to the ultrasound probe. The doctor then pushes the needle through the wall of the rectum into the prostate. The doctor uses a thin, hollow needle to collect samples of tissue from different parts of the prostate. This type of biopsy is called a core biopsy or core needle biopsy.
