The PSA test can also be useful if you have already been diagnosed with prostate cancer.
Further Testing For Advanced CancerIf there’s a significant chance the cancer has spread from your prostate to other parts of the body, further tests may be recommended. These include:
New Prostate Cancer Blood TestIf you have an abnormal PSA score, your doctor may recommend another newertest that gives a better sense of yourprostate cancer risk. The prostate health index is one such test that is a more accurateblood test and measures your risk for having prostate cancer. Its approvedby the FDA for men who have PSA scores between 4 and 10. What are the benefits of the PHI test?
If you score low on the PHI test, your doctor may recommend monitoring youover time to see if your levels rise enough to cause concern. Don’t Miss: What Age To Get Tested For Prostate Cancer Use In Men Who Might Have Prostate CancerThe PSA blood test is used mainly to screen for prostate cancer in men without symptoms. Its also one of the first tests done in men who have symptoms that might be caused by prostate cancer. PSA in the blood is measured in units called nanograms per milliliter . The chance of having prostate cancer goes up as the PSA level goes up, but there is no set cutoff point that can tell for sure if a man does or doesnt have prostate cancer. Many doctors use a PSA cutoff point of 4 ng/mL or higher when deciding if a man might need further testing, while others might recommend it starting at a lower level, such as 2.5 or 3.
If your PSA level is high, you might need further tests to look for prostate cancer. To learn more about how the PSA test is used to look for cancer, including factors that can affect PSA levels, special types of PSA tests, and what the next steps might be if you have an abnormal PSA level, see Screening Tests for Prostate Cancer. What Have Randomized Trials Of Prostate Cancer Screening Found![]() Several large, randomized trials of prostate cancer screening have been carried out. One of the largest is the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, which NCI conducted to determine whether certain screening tests can help reduce the numbers of deaths from several common cancers. In the prostate portion of the trial, the PSA test and digital rectal exam were evaluated for their ability to decrease a mans chances of dying from prostate cancer. The PLCO investigators found that men who underwent annual prostate cancer screening had a higher incidence of prostate cancer than men in the control group but had about the same rate of deaths from the disease . Overall, the results suggest that many men were treated for prostate cancers that would not have been detected in their lifetime without screening. Consequently, these men were exposed unnecessarily to the potential harms of treatment. A second large trial, the European Randomized Study of Screening for Prostate Cancer , compared prostate cancer deaths in men randomly assigned to PSA-based screening or no screening. As in the PLCO, men in ERSPC who were screened for prostate cancer had a higher incidence of the disease than control men. In contrast to the PLCO, however, men who were screened had a lower rate of death from prostate cancer . The United States Preventive Services Task Force has estimated that, for every 1,000 men ages 55 to 69 years who are screened for 13 years : Read Also: Can Urgent Care Treat Prostatitis Psa Test: The Current Prostate Screening StandardBefore recommending when you should be screened for prostate cancer, yourdoctor will consider many factors, such as:
If your doctor determines you should undergo screening, he or she will mostlikely recommend the PSA test. For more than 30 years, the PSA test hasbeen the gold standard in prostate cancer screening. This simple blood testmeasures how much prostate-specific antigen is in your blood. What Tests Detect Prostate Cancer EarlyBecause prostate cancer cant necessarily be detected at home, its a good idea to learn about the tests that provide early detection. Keep in mind that these tests cant decipher whether or not you have prostate cancer and, following the test, your doctor will most likely suggest a prostate biopsy. If youre wondering how to check for prostate cancer at home, your best bet is to leave it to your health care professional.

When used in screening, the PSA test can help detect small tumors. Having a small tumor found and treated may not, however, reduce the chance of dying from prostate cancer. That is because many tumors found through PSA testing grow so slowly that they are unlikely to be life threatening. Detecting such tumors is called overdiagnosis, and treating them is called overtreatment. Overtreatment exposes a person unnecessarily to the potential complications associated with prostate surgery and radiation therapy. These include urinary , gastrointestinal , and sexual side effects . In addition, finding cancer early may not help someone who has a fast-growing or aggressive prostate tumor that may have spread to other parts of the body before being detected. The PSA test may give false-positive results. A false-positive test result occurs when the PSA level is elevated but no cancer is actually present. A false-positive test result may create anxiety and lead to additional medical procedures, such as a prostate biopsy, that can be harmful. Possible side effects of biopsies include serious infections, pain, and bleeding. False-positive test results are common with PSA screening only about 25% of people who have a prostate biopsy due to an elevated PSA level are found to have prostate cancer when a biopsy is done . Screening For Prostate Cancer: What Do You Need To Know About Digital Rectal Examination
Tests to Diagnose and Monitor Prostate Cancer
The digital rectal examination is a clinical examination during which the attending physician makes a series of gestures to feel the patients prostate at the level of his rectum. This touch is risk-free for the patient and only lasts a maximum of two minutes. During the digital rectal examination, the doctor checks the consistency, texture and volume of the surface of the prostate. He can therefore detect abnormalities such as an enlarged prostate, abnormally hard or presenting nodules. In order to deepen this examination, the doctor will refer the patient to a urologist for more precision. However, it should be kept in mind that the presence of an abnormality in the prostate is not synonymous with the existence of a prostate cancer. A complementary examination makes it possible to establish a diagnosis with certainty.

A Digital Rectal Exam is a physical exam that is done when a doctor or nurse inserts a gloved, lubricated finger into the rectum to estimate the size of the prostate and feel for lumps or other abnormalities. Talk to your doctor about your risk for prostate cancer and when to begin screening. If you do not have a doctor, do not have insurance, or cannot afford a test, find out if free screenings are available in your area on our Free Testing Map.

Watch prostate cancer experts Dr. Lowentritt and Dr. Siegel in this video discuss screening and diagnosis: Recommended Reading: Which Is The Most Common Type Of Prostate Surgery Psa Screening Blood TestThe American Cancer Society reports that men with a total PSA level of between 4 and 10 have roughly a 1 in 4 chance of having prostate cancer. With a total PSA of over 10, the chance of having prostate cancer rises to over 50%. Following the PSA test, if the levels are high, a doctor may suggest a repeat screening test or a prostate biopsy. In addition to prostate cancer, there are many other factors that can affect a mans PSA levels. Reasons for a High PSA:
Reasons for a Low PSA: How Soon Will Prostate Test Results Be Available![]() Results for simple medical tests such as some urodynamic tests, cystoscopy, and abdominal ultrasound are often available soon after the test. The results of other medical tests such as PSA blood test and prostate tissue biopsy may take several days to come back. A health care provider will talk with the patient about the results and possible treatments for the problem. Don’t Miss: How Do They Biopsy A Prostate What Is Done If A Screening Test Shows An Elevated Psa LevelIf someone who has no symptoms of prostate cancer chooses to undergo prostate cancer screening and is found to have an elevated PSA level, the doctor may recommend another PSA test to confirm the original finding. If the PSA level is still high, the doctor may recommend that the person continue with PSA tests and digital rectal exams at regular intervals to watch for any changes over time . If the PSA level continues to rise or a suspicious lump is detected during a DRE, the doctor may recommend additional tests to determine the nature of the problem. These may include imaging tests, such as magnetic resonance imaging or high-resolution micro-ultrasound. Alternatively, the doctor may recommend a prostate biopsy. During this procedure, multiple samples of prostate tissue are collected by inserting hollow needles into the prostate and then withdrawing them. The biopsy needle may be inserted through the wall of the rectum or through the perineum . A pathologist then examines the collected tissue under a microscope. Although both biopsy techniques are guided by ultrasound imaging so the doctor can view the prostate during the biopsy procedure, ultrasound cannot be used alone to diagnose prostate cancer. An MRI-guided biopsy may be performed for patients with suspicious areas seen on MRI. Getting A Prostate BiopsyFor some men, getting a prostate biopsy might be the best option, especially if the initial PSA level is high. A biopsy is a procedure in which small samples of the prostate are removed and then looked at under a microscope. This test is the only way to know for sure if a man has prostate cancer. If prostate cancer is found on a biopsy, this test can also help tell how likely it is that the cancer will grow and spread quickly. For more details on the prostate biopsy and how it is done, see Tests to Diagnose and Stage Prostate Cancer.
