Imaging Tests For Prostate Cancer

Prostate Cancer Symptoms And The PSA Blood Test – Macmillan Cancer Support

Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. One or more imaging tests might be used:

  • To look for cancer in the prostate
  • To help the doctor see the prostate during certain procedures
  • To look for spread of prostate cancer to other parts of the body

Which tests you might need will depend on the situation. For example, a prostate biopsy is typically done with transrectal ultrasound and/or MRI to help guide the biopsy. 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.

The imaging tests used most often to look for prostate cancer spread include:

What Do The Results Mean

There is no specific normal or abnormal level for PSA in blood. In general, the higher your PSA level, the more likely it is that you have cancer. But it’s possible to have a high PSA without prostate cancer, or a low PSA with prostate cancer.

If you had a PSA test for a prostate cancer screening or because you have prostate symptoms:

  • High PSA levels can mean you have prostate cancer or a prostate condition that’s not cancer, such as an infection or an enlarged prostate. If your PSA levels are higher than normal, your provider may talk with you about having more tests to diagnose the cause. These tests may include:
  • Another PSA test, more commonly if you don’t have any symptoms. PSA levels can go up and down, so it helpful to see if your PSA levels change over time.
  • A digital rectal exam . For this test, your provider inserts a gloved, lubricated finger into your rectum to feel your prostate for lumps or anything unusual.
  • A urine test. A sample of your urine is tested for infection.
  • A prostate biopsy. A biopsy is minor surgery. A doctor removes samples of tissue from your prostate so it can be studied under a microscope to look for cancer cells. A biopsy is the only way to diagnose cancer. It may be recommended if your provider thinks you may have prostate cancer.

If you have questions about your results, talk with your provider.

When Should I Have A Prostate Check

Generally, if you aged 50 years or older and have any urinary symptoms, you should let your doctor know. They will discuss with you whether or not you should have a prostate check.

Symptoms include:

  • blood in your pee.

If you have no symptoms, it is recommended that you get checked if you:

  • you are a man aged 5070 years old but dont have any family history
  • you are a man aged 4070 years old and your father or brother has had prostate cancer
  • you are a man aged more than 70 years old and you have family history of prostate cancer or you have had an abnormal PSA test previously, and you have a life expectancy of more than 10 years.

Having a prostate check is your decision. The tests for prostate cancer can be uncomfortable but they may reduce your chance of being harmed or dying from prostate cancer.

If your test results suggest you are at risk of cancer, you will need to decide whether to have further testing and possibly treatment. In making this decision, you will need to consider whether your quality of life will be better living with a slow growing cancer than having treatments, which may cause you more harm than the cancer ever will.

Your doctor can help you weigh up the benefits and risks of being tested, by taking into consideration factors such as your age and family history.

Arenal panel is used to help monitor and diagnose conditions affecting kidney function, notably kidney failure, which could aggravate cancer. Levels of urea increase in cases of kidney failure . High levels of urea are not unique to kidney failure and can also occur in the case of high protein diets, dehydration or infection.

Standard values:

0.6-1.2 mg/dL

Why this test?

Creatinine levels reflect kidney function. Creatinine is a product of skeletal muscle breakdown. It is mainly eliminated by the kidneys . Kidney function can be estimated from the renal clearance of creatinine or from its concentration in the blood using formulas for estimating the glomerular filtration rate .

Should I Have A Psa Test

PSA Test for Prostate Cancer

If you have no symptoms of prostate cancer and are thinking about having a PSA test, you should ask your doctor about the risks and benefits.

While some studies suggest PSA reduces mortality on a population basis, the test picks up large numbers of cancers that would have caused no symptoms or harm in the patient. This is known as overdiagnosis. Overdiagnosis of prostate cancer can lead to unnecessary treatments that have side effects such as sexual impotence, urinary incontinence and bowel problems.

It is important to balance the potential benefit of detecting a prostate cancer early against the risk that detection and treatment may not be necessary. Treatment may affect your lifestyle but it may also save your life.

Make your own decision about whether to be tested after a discussion with your doctor. Ensure you get good quality information to make an informed decision.

Screening tests for breast, bowel and cervical cancer can save lives, but there is still confusion around PSA testing for prostate cancer. Find more information here.

Remember, if you have any concerns or questions, please contact your doctor.

Should I Have A Prostate Cancer Screening Test

Routine testing for prostate cancer in all men without symptoms is not recommended in New Zealand at present. Being tested for prostate cancer is your choice. Learning about the pros and cons of prostate testing can help you decide if it is right for you.

To help you decide if a prostate check is right for you, the Ministry of Health has developed the Kupe website. It will help you understand the risks, benefits and implications of prostate testing, so you can have an informed conversation with your doctor.

If you are unsure about whether you need to get tested for prostate cancer, contact your GP for a discussion on the risks and benefits of testing.

What Is The First Test For Detecting Prostate Problems

The first test for detecting prostate problems is a blood test to measure prostate-specific antigen , a protein made only by the prostate gland. This test is often included in routine physical exams for men older than age 50. Because African American men have higher rates of getting, and dying from, prostate cancer than men of other racial or ethnic groups in the United States, medical organizations recommend a PSA blood test be given starting at age 40 for African American men. Medical organizations also recommend a PSA blood test be given starting at age 40 for men with a family history of prostate cancer. Some medical organizations even recommend a PSA blood test be given to all men starting at age 40.

If urination problems are present or if a PSA blood test indicates a problem, additional tests may be ordered. These tests may require a patient to change his diet or fluid intake or to stop taking medications. If the tests involve inserting instruments into the urethra or rectum, antibiotics may be given before and after the test to prevent infection.

How Is Prostate Cancer Detected

There is no single test to detect prostate cancer. The two most common tests are the prostate specific antigen blood test and the digital rectal examination .

The PSA test measures the level of PSA in your blood. It does not specifically test for cancer. Virtually all PSA is produced by the prostate gland. The normal range depends on your age. A PSA above the typical range may indicate the possibility of prostate cancer. However, two-thirds of cases of elevated PSA are due to noncancerous conditions such as prostatitis and BPH.

A DRE is generally conducted by a urologist to feel the prostate. While DRE is no longer recommended as a routine test for men who do not have symptoms of prostate cancer, it may be used to check for any changes in the prostate before doing a biopsy.

If either of these tests suggest an abnormality, other tests are necessary to confirm a diagnosis of prostate cancer, usually a magnetic resonance imaging scan and transrectal ultrasound biopsy.

What If My Test Results Are Abnormal

If the results of early detection tests like the PSA screening or the digital rectal exam suggest that you might have prostate cancer, your doctor will conduct further testing. The PSA may be repeated, or you may be sent to a specialist for more tests such as a transrectal ultrasound and a prostate biopsy.

In a prostate biopsy, a tissue sample is taken from your prostate. Cancer can only be diagnosed with a tissue sample.

Recent research has yielded additional tests that in addition to the PSA and subsequent DRE and Biopsy that can give a doctor more information on to determine the probability of both finding cancer during a biopsy and determining how aggressive that cancer is likely to be. Read more on those tests.

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.

Who Can Have The Psa Test

If you are over 50, you can ask your GP for a PSA test. GPs do not routinely offer PSA testing as part of a general health check, or if you do not have any symptoms.

If you ask for a PSA test, your GP will advise you to think carefully about the benefits and disadvantages.

If you have a higher risk of prostate cancer, it is important to talk to your GP about your personal risk. This is even if you do not have any symptoms. Early prostate cancer does not usually cause symptoms.

Talking to your GP can help you to make an informed decision about having a PSA test.

Psa Levels In The Blood

Standard values:

< 4.0 ng/mL

Why this test? What is PSA?

PSA is the acronym for Prostatic Specific Antigen. It is a protein produced by the prostate and is , but a small quantity passes into the bloodstream. Thus, in a healthy individual, PSA is found in small quantities in the blood. It is important to be aware that sexual intercourse or rectal examinations should be avoided in the 48 hours before the PSA test, as they can cause PSA levels to rise and interfere with the test results.

Results of this test:

Abnormally high levels may indicate the presence of prostate cancer. If the rate is higher than the standard value, the diagnostic process requires additional tests. However, an elevated level in the blood can also be explained by age or by a benign adenoma or prostatitis. Moreover, a normal PSA level does not mean that cancer cannot be ruled out.

How Is The Psa Test Used In Men Who Have Been Treated For Prostate Cancer

PSA test, Prostate Cancer, Prostate Specific Antigen, PSA Level, PSA ...

The PSA test is used to monitor men after surgery or radiation therapy for prostate cancer to see if their cancer has recurred . If a mans PSA level begins to rise after prostate cancer treatment, it may be the first sign of a recurrence. Such a biochemical relapse typically appears months or years before the recurrence causes symptoms.

However, a single elevated PSA measurement in someone who has a history of prostate cancer does not always mean that the cancer has come back. Someone who has been treated for prostate cancer should discuss an elevated PSA level with their doctor. The doctor may recommend repeating the PSA test or performing other tests to check for evidence of a recurrence. The doctor may look for a trend of rising PSA level over time rather than a single elevated PSA level.

A rising trend in PSA level over time in combination with other findings, such as an abnormal result on imaging tests, may lead the doctor to recommend further cancer treatment.

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 :

Should You Know Your Psa Level

Instead of a national screening programme, there is an informed choice programme, called prostate cancer risk management, for healthy men aged 50 or over who ask their GP about PSA testing. It aims to give men good information on the pros and cons of a PSA test.

If youâre a man aged 50 or over and decide to have your PSA levels tested after talking to your GP, they can arrange for it to be carried out free on the NHS.

If results show you have a raised level of PSA, your GP may suggest further tests.

What Does A High Psa Level Mean

High PSA levels could be a sign of prostate cancer or a different condition like prostatitis or an enlarged prostate.

Other things can affect your PSA level:

  • Age. Your PSA will normally go up slowly as you get older, even if you have no prostate problems.
  • Medications. Some drugs may affect blood PSA levels. Tell your doctor if youâre taking dutasteride or finasteride . These drugs may falsely lower PSA levels by half of what they should be.

If your PSA level is high, your doctor may suggest that you get a prostate biopsy to test for cancer.

Clear Answers On Unclear Psa Results

Should I have a PSA Prostate Cancer Screening Test?

Today, the initial step to diagnose prostate cancer is by testing PSA together with a digital rectal examination . The PSA test is a well-established prostate-specific marker that measures the concentration of PSA molecules in a blood sample. A high level of PSA can be a sign of prostate cancer. Therefore, clinical guidelines recommend a confirmatory prostate biopsy, if PSA > 3 ng/ml. But PSA levels can also be raised for many other reasons including infections, prostate stimulation, vigorous exercise or even certain medications. PSA results are confusing for many patients and even physicians. Patients are sent for time-consuming and anxiety-causing additional examinations, especially when a biopsy is being considered. Currently, over 50% of biopsies with elevated PSA are negative or clinically insignificant. This means overdiagnosis and overtreatment that impacts the physician’s routine, our healthcare system, and the quality of patient’s lives.

Prostate Specific Antigen Test

A blood test called a prostate specific antigen test measures the level of PSA in the blood. PSA is a substance made by the prostate. The levels of PSA in the blood can be higher in men who have prostate cancer. The PSA level may also be elevated in other conditions that affect the prostate.

As a rule, the higher the PSA level in the blood, the more likely a prostate problem is present. But many factors, such as age and race, can affect PSA levels. Some prostate glands make more PSA than others.

PSA levels also can be affected by

  • Certain medical procedures.
