They will usually take some from each side of the prostate. A spring loaded tool punches the needle through the rectal wall into the prostate gland. Each sample is a minute cylindrical core of cells. During this operation, a doctor will make a small cut between the anus and the scrotum.
To extract the samples, they will insert the needle through the cut and into the prostate. The doctor may use an ultrasound or MRI scan to guide the procedure. An MRI guided biopsy can provide more detailed images. These may take 30—90 minutes and can involve the use of a contrast dye. The individual will be monitored for up to an hour afterward.
A doctor will usually administer an anesthetic injection into the rectum area before the procedure. During the biopsy, the individual should not feel any pain, but they might feel a pinch as the needle enters the tissue.
They will need to know about any medications and supplements the individual is taking and any allergies or other medical conditions. It is also useful to ask questions and find out as much as possible beforehand about the biopsy and what the results might mean.
Having this information can help them feel more confident and in control of the process. The doctor may prescribe an antibiotic to reduce the risk of an infection occurring after the biopsy.
After a biopsy, a person may experience :. If symptoms are significant, or if they worsen rather than improve, the person should contact their doctor. Are there any other options for testing for prostate cancer?
Find out here. Some discomfort is likely during the recovery time, but sometimes, more severe complications can arise. In rare cases, sepsis can occur. Sepsis is a potentially life threatening infection that needs urgent medical attention.
Signs and symptoms of sepsis include :. Learn more here about sepsis. A doctor will normally carry out these tests before recommending a biopsy. However, only a biopsy can confirm the presence of cancer. What tests are there for prostate cancer? A biopsy will show if the prostate cells are normal or cancerous.
If the cells are normal, the doctor may recommend no further action. If cancer is present, the biopsy can also reveal to what extent the cells have changed and how quickly cancer is likely to progress. These range from grade 1, which looks normal, to grade 5, where significant changes have occurred. A biopsy can also show how far cancer has spread. Transrectal biopsy of the prostate Open pop-up dialog box Close. Transrectal biopsy of the prostate During a transrectal biopsy, a biopsy gun quickly projects a thin needle into suspect areas of the prostate gland, and small sections of tissue are removed for analysis.

Prostate cancer diagnosis. Ferri FF. Prostate cancer. If you are found to have prostate cancer, you might need imaging tests of other parts of your body to look for possible cancer spread.
Men with a normal DRE result, a low PSA, and a low Gleason score may not need any other tests because the chance that the cancer has spread is so low. For this test, a small probe about the width of a finger is lubricated and placed in your rectum.
The probe gives off sound waves that enter the prostate and create echoes. The probe picks up the echoes, and a computer turns them into a black and white image of the prostate. You will feel some pressure when the probe is inserted, but it is usually not painful. The area may be numbed before the procedure. Newer forms of TRUS, such as color Doppler ultrasound, might be even more helpful in some situations.
MRI scans create detailed images of soft tissues in the body using radio waves and strong magnets. MRI scans can give doctors a very clear picture of the prostate and nearby areas. A contrast material called gadolinium may be injected into a vein before the scan to better see details. To improve the accuracy of the MRI, you might have a probe, called an endorectal coil , placed inside your rectum for the scan. This can be uncomfortable for some men.
If needed, you can be given medicine to make you feel sleepy sedation. Multiparametric MRI: This newer MRI technique can be used to help better define possible areas of cancer in the prostate, as well as to get an idea of how quickly a cancer might grow. It can also help show if the cancer has grown outside the prostate or spread to other parts of the body.
The results of the different scans are then compared to help find abnormal areas. In this system, abnormal areas in the prostate are assigned a category on a scale ranging from PI-RADS 1 very unlikely to be a clinically significant cancer to PI-RADS 5 very likely to be a clinically significant cancer.
This can help ensure the doctor gets biopsy samples from any suspicious areas seen on the images. If prostate cancer spreads to distant parts of the body, it often goes to the bones first. A bone scan can help show if cancer has reached the bones. For this test, you are injected with a small amount of low-level radioactive material, which settles in damaged areas of bone throughout the body. A special camera detects the radioactivity and creates a picture of your skeleton.
A bone scan might suggest cancer in the bone, but to make an accurate diagnosis, other tests such as plain x-rays, CT or MRI scans, or even a bone biopsy might be needed. A PET scan is similar to a bone scan, in that a slightly radioactive substance known as a tracer is injected into the blood, which can then be detected with a special camera. But PET scans use different tracers that collect mainly in cancer cells. However, newer tracers, such as fluciclovine F18, sodium fluoride F18, and choline C11, have been found to be better at detecting prostate cancer cells.
Doctors are still learning about the best ways to use these newer types of PET scans, and some of them might not be available yet in all imaging centers. A CT scan uses x-rays to make detailed, cross-sectional images of your body.
Still, it can sometimes help tell if prostate cancer has spread into nearby lymph nodes. If your prostate cancer has come back after treatment, the CT scan can often tell if it is growing into other organs or structures in your pelvis.
CT scans are not as useful as magnetic resonance imaging MRI for looking at the prostate gland itself. In a lymph node biopsy, also known as lymph node dissection or lymphadenectomy , one or more lymph nodes are removed to see if they have cancer cells.
