What Is The Psa Test

10 Warning Signs of Prostate Cancer

Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter of blood.

The blood level of PSA is often elevated in people with prostate cancer, and the PSA test was originally approved by the FDA in 1986 to monitor the progression of prostate cancer in men who had already been diagnosed with the disease. In 1994, FDA approved the PSA test to be used in conjunction with a digital rectal exam to aid in the detection of prostate cancer in men 50 years and older. Until about 2008, many doctors and professional organizations had encouraged yearly PSA screening for prostate cancer beginning at age 50.

PSA testing is also often used by health care providers for individuals who report prostate symptoms to help determine the nature of the problem.

In addition to prostate cancer, several benign conditions can cause a persons PSA level to rise, particularly prostatitis and benign prostatic hyperplasia . There is no evidence that either condition leads to prostate cancer, but someone can have one or both of these conditions and develop prostate cancer as well.

The Role Of Psa In Choosing The Best Treatment

If you have received a diagnosis of prostate cancer, your PSA levels can be used along with the results of other tests and physical exams and your tumors Gleason score to help determine which tests are needed for further evaluation and to decide on the best treatment plan. After treatment has begun, your PSA and other tests will be used to determine how well the treatment is working: The more successful the therapy, the lower the PSA.

What Is A Prostate Ultrasound Used For

A prostate ultrasound is used to check your prostate gland using ultrasound imagery. The procedure provides your doctor with black-and-white images of your prostate and the surrounding tissues. Your doctor usually wont do this as part of a physical examination, but they may recommend it if:

  • youre over 40

A prostate ultrasound can also be used to help your doctor take a tissue sample, or biopsy, from your prostate.

When Is The Psma Pet Test Used

Your doctor might order a PSMA PET scan if youve recently received a new diagnosis of prostate cancer and they think it may have spread to other parts of your body. Or your doctor may use it to get a better idea of where prostate cancer has spread.

Prostate cancer is usually diagnosed in its early stages, before it has spread. However, some people are at heightened risk of metastatic prostate cancer.

Your doctor might order PSMA PET-CT at the time you are diagnosed with prostate cancer if you have any risk factors for metastatic disease, Dr. Michael Feuerstein, a urologist at Lenox Hill Hospital in New York City, tells Healthline.

According to Feuerstein, doctors use the following measurements to assess the risk of metastatic prostate cancer:

  • Prostate-specific antigen . PSA is a protein made by the prostate thats found in the semen and blood. It tends to be elevated in people with prostate cancer. A PSA blood test is one of the first tests doctors order to diagnose prostate cancer. Youre considered at risk of metastatic prostate cancer if you have a PSA blood level of 20 or higher.
  • Gleason grade. This system assigns a score to classify how many abnormal prostate cancer cells are found in a tissue biopsy. A Gleason grade of 7 or higher puts you at higher risk of metastatic prostate cancer.

Your doctor might also order the PSMA PET test if you still have detectable prostate cancer after undergoing surgery to treat it, says Feuerstein.

Prostate Cancer Stages

Surgical procedures to remove the diseased prostate are usually necessary. Surgical procedures are not always necessary. If the disease is caused by bacterial infections, a doctor can treat the symptoms using alpha-blockers or surgery. Physical therapy, relaxation exercises, and warm baths are all recommended. A physician may also prescribe antibiotics to cure the infection. A bacterial infection can also cause a recurrence of the condition.

An enlarged prostate can be uncomfortable for both men and women. Some of the symptoms of an enlarged male reproductive organ include a weakened urine stream, urgent need to urinate, and urinary tract infections. BPH can also cause damage to the kidneys. A sudden inability to urinate can be life-threatening, as it can lead to bladder and kidney damage. Unfortunately, most men with enlarged prostrates put up with the symptoms for years before they seek treatment. However, many of the men with symptoms finally decide to go to a doctor for proper gynecological evaluation and to begin enlarged prostatic therapy.

What Are The Symptoms Of Prostate Problems

The symptoms of prostate problems may include

  • urinary retentionthe inability to empty the bladder completely
  • urinary frequencyurination eight or more times a day
  • urinary urgencythe inability to delay urination
  • urinary incontinencethe accidental loss of urine
  • nocturiafrequent urination at night
  • trouble beginning a urine stream
  • weak or interrupted urine stream
  • blockage of urine
  • urine that has an unusual color or odor
  • pain after ejaculation or during urination

Different prostate problems may have similar symptoms. For example, one man with prostatitis and another with BPH may both experience urinary urgency. Sometimes symptoms for the same prostate problem differ among individuals. For example, one man with BPH may have trouble beginning a urine stream, while another may experience nocturia. A man in the early stages of prostate cancer may have no symptoms at all. Because of this confusing array of symptoms, a thorough medical exam and testing are vital.

Screening Information For Prostate Cancer

Screening for prostate cancer is done to find evidence of cancer in otherwise healthy adults. Two tests are commonly used to screen for prostate cancer:

Digital rectal examination

A DRE is a test in which the doctor inserts a gloved, lubricated finger into the rectum and feels the surface of the prostate through the bowel wall for any irregularities.

PSA blood test

There is controversy about using the PSA test to look for prostate cancer in people with no symptoms of the disease. On the one hand, the PSA test is useful for detecting early-stage prostate cancer, especially in those with many risk factors, which helps some get the treatment they need before the cancer grows and spreads. On the other hand, PSA screening may find very-slow-growing prostate cancers that would never threaten someone’s life. As a result, screening for prostate cancer using PSA may lead to treatments that are not needed, which can cause side effects and seriously affect a person’s quality of life.

ASCO recommends that people with no symptoms of prostate cancer and who are expected to live less than 10 years do not receive PSA screening. For those expected to live longer than 10 years, ASCO recommends that they talk with their doctor to find out if the test is appropriate for them.

Other organizations have different recommendations for screening:

Discuss Prostate Cancer Testing With Your Doctor

Medical authorities do not recommend that all men should be tested for prostate cancer. In fact, most authorities suggest that men should make their own choice about whether or not to have a PSA test. If you decide to be tested, it is recommended that it should be done every two years from 50 to 69 years of age, and only if your health is such that you expect to live for at least another seven years.

Men at high risk of prostate cancer, such as men with a family history of prostate cancer , or men who have previously had an elevated test result, can start two-yearly testing from age 45. Your doctor can help you decide whether this is necessary.

While there is now some evidence that regular testing may prevent prostate cancer deaths, there are concerns that many men may be diagnosed and treated unnecessarily as a result of being screened, with a high cost to their health and quality of life .

However, the option of active surveillance, where a low-risk cancer is watched closely instead of being treated, helps to lower these risks. Active surveillance is now used quite commonly in Australia for men with low-risk prostate cancer.

If you are unsure whether or not to be tested after considering the benefits and uncertainties of testing and your own risk of prostate cancer, discuss it with your doctor.

In Australia, if you choose to be tested for prostate cancer the tests are covered by Medicare.

Further Tests For Prostate Cancer

What it’s like to go for a rectal screening for prostate cancer

If results of the PSA test or the DRE are abnormal, a urologist will likely recommend a biopsy, where small samples of tissue are removed from the prostate and examined.

If cancer is diagnosed, other tests may be used to check the progression of the cancer, including:

  • magnetic resonance imaging scan of the prostate – often done before a biopsy
  • bone scan – to check whether or not cancer cells have spread to the bones
  • computed tomography scan – a specialised x-ray
  • pelvic lymph node dissection – a nearby lymph node is removed and examined to check whether or not cancer cells have entered the lymphatic system .

Do I Need The Psa Test

The PSA test is not recommended for men who dont have symptoms of prostate cancer, as it can lead to unnecessary investigations and treatments that have serious side effects.

If you are at higher risk of developing prostate cancer, or if you have symptoms that may indicate cancer, PSA testing may be of more benefit.

Cancer Council Australia and the Royal Australian College of General Practitioners both recommend against routine screening in men without symptoms. That is because the PSA test is not very accurate for screening men without symptoms. High PSA levels can be due to many things, and cancer is just one of them. And a man with prostate cancer can have a normal PSA level.

As there is a range of risks and potential benefits of PSA testing, talk to your doctor to help make an informed decision.

What Is Done If A Screening Test Shows An Elevated Psa Level

If 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 Biopsy

Prostate Cancer: Symptoms, Diagnosis &  Treatment

For 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.

How Are Prostate Problems Diagnosed

To diagnose prostate problems, the health care provider will perform a digital rectal exam . The health care provider will also ask the patient

  • when the problem began and how often it occurs
  • what symptoms are present
  • whether he has a history of recurrent urinary tract infections
  • what medications he takes, both prescription and those bought over the counter
  • the amount of fluid he typically drinks each day
  • whether he consumes caffeine and alcohol
  • about his general medical history, including any major illnesses or surgeries

Answers to these questions will help the health care provider identify the problem or determine what medical tests are needed. Diagnosing BPH may require a series of medical exams and tests.

Factors That Might Affect Psa Levels

One reason its hard to use a set cutoff point with the PSA test when looking for prostate cancer is that a number of factors other than cancer can also affect PSA levels.

Factors that might raise PSA levels include:

  • An enlarged prostate: Conditions such as benign prostatic hyperplasia, a non-cancerous enlargement of the prostate that affects many men as they grow older, can raise PSA levels.
  • Older age: PSA levels normally go up slowly as you get older, even if you have no prostate abnormality.
  • Prostatitis: This is an infection or inflammation of the prostate gland, which can raise PSA levels.
  • Ejaculation: Thiscan make the PSA go up for a short time. This is why some doctors suggest that men abstain from ejaculation for a day or two before testing.
  • Riding a bicycle: Some studies have suggested that cycling may raise PSA levels for a short time , although not all studies have found this.
  • Certain urologic procedures: Some procedures done in a doctors office that affect the prostate, such as a prostate biopsy or cystoscopy, can raise PSA levels for a short time. Some studies have suggested that a digital rectal exam might raise PSA levels slightly, although other studies have not found this. Still, if both a PSA test and a DRE are being done during a doctor visit, some doctors advise having the blood drawn for the PSA before having the DRE, just in case.
  • Certain medicines: Taking male hormones like testosterone may cause a rise in PSA.

What Happens After The Prostate Tests

Urodynamic tests and cystoscopy may cause mild discomfort for a few hours after the procedures. Drinking an 8-ounce glass of water every half-hour for 2 hours may help reduce discomfort. The health care provider may recommend taking a warm bath or holding a warm, damp washcloth over the urethral opening to relieve discomfort. A prostate biopsy may produce pain in the area of the rectum and the perineum, which is between the rectum and the scrotum. A prostate biopsy may also produce blood in urine and semen.

An antibiotic may be prescribed for 1 or 2 days to prevent infection.

Patients with signs of infectionincluding pain, chills, or fevershould call their health care provider immediately.

Prostate-specific Antigen (PSA) Tests for Prostate Cancer

The main purpose of the prostate is to produce semen, a milky fluid that sperm swims in. During puberty, the body produces semen in a large number of cases, including enlarged prostate. This fluid causes the prostate to swell and cause a number of bladder-related symptoms. This is why the prostate is important to the body. It can be caused by many factors, including infection and inflammation.

A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.

While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.

Transrectal Ultrasound With Prostate Biopsy

Transrectal ultrasound is most often used to examine the prostate. In a transrectal ultrasound, the health care provider inserts a transducer slightly larger than a pen into the mans rectum next to the prostate. The ultrasound image shows the size of the prostate and any abnormal-looking areas, such as tumors. Transrectal ultrasound cannot definitively identify prostate cancer.

To determine whether a tumor is cancerous, the health care provider uses the transducer and ultrasound images to guide a needle to the tumor. The needle is then used to remove a few pieces of prostate tissue for examination with a microscope. This process, called biopsy, can reveal whether prostate cancer is present. A transrectal ultrasound with prostate biopsy is usually performed by a doctor in a health care providers office, outpatient center, or hospital with light sedation and local anesthesia. The biopsied prostate tissue is examined in a laboratory by a pathologista doctor who specializes in diagnosing diseases.
