Positive Psa Score Association With Other Conditions
The amount of PSA in your blood test may increase with other prostate conditions such prostatitis, enlarged prostate , or within two days after ejaculation.
Rest assured, even though your results may be high, it doesnt necessarily mean you have prostate cancer. Just a greater risk of developing it.
Who Should Have A Psa Test
Talk to your doctor about the PSA test. Make an informed decision about whether the PSA test is right for you by talking with your doctor and considering your personal risk factors.
- If you are at average risk of developing prostate cancer, consider testing from age 50.
- If you are at high risk of developing prostate cancer, consider testing from age 45. Black men and those with a family history of prostate cancer are considered to be at high risk.
Your PSA levels will determine how often you get tested. The decision to stop testing is based on your PSA levels, age and general health.
What Is A Cea Test
CEA stands for carcinoembryonic antigen. It is a protein found in the tissues of a developing baby. CEA levels normally become very low or disappear after birth. Healthy adults should have very little or no CEA in their body.
This test measures the amount of CEA in the blood, and sometimes in other body fluids. CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body.
A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.
A CEA test can’t tell you what kind of cancer you have, or even whether you have cancer. So the test is not used for cancer screening or diagnosis. But if you’ve already been diagnosed with cancer, a CEA test can help monitor the effectiveness of your treatment and/or help find out if the disease has spread to other parts of your body.
Other names: CEA assay, CEA blood test, carcinoembryonic antigen test
Questions To Think About Before Having A Psa Test
To help you make your decision, you could think about the following questions:
- What would you do if your PSA level is high?
- What would you do if further tests find that you have an early prostate cancer?
- What difference will it make for you to know about an early prostate cancer?
Before you decide whether to have the PSA test, you may want to talk to your GP about it. You can also call our cancer support specialists on 0808 808 00 00. They can discuss the options with you and send you more information.
Screening For Prostate Cancer
Prostate cancer is typically treatable if caught early. More than 90 percent of prostate cancers are found when the disease is in the beginning stages, confined to the prostate and nearby organs.
Unlike screenings for breast and colon cancers, there are no universal screening guidelines for prostate cancer. The U.S. Preventive Services Task Force recommends that men age 55 to 69 weigh the benefits and risks before deciding whether they should undergo screening, which is typically performed with a blood test that measures levels of a protein called prostate-specific antigen .
However, men in high-risk groupssuch as those who are of African-American descent and/or have a first-degree relative diagnosed with prostate cancer before age 65should consider speaking with their doctor about starting screenings at an earlier age.
Men older than 70 shouldnt be routinely screened for prostate cancer, according to the USPSTF.
Regardless of age or risk factors, men should get checked if they suddenly experience issues with urination, erectile dysfunction or unexplained pain.
The USPSTF suggests that, before deciding on a screening, men should seek expert advice about the benefits and harms of screening. Risks may include:
- False positives
- Complications and side effects from biopsies to confirm a diagnosis
- The possibility that a prostate cancer diagnosis wont extend lifespan or improve quality of life
Tests To Diagnose And Stage Prostate Cancer
Most prostate cancers are first found as a result of screening. Early prostate cancers usually dont cause symptoms, but more advanced cancers are sometimes first found because of symptoms they cause.
If prostate cancer is suspected based on results of screening tests or symptoms, tests will be needed to be sure. If youre seeing your primary care doctor, you might be referred to a urologist, a doctor who treats cancers of the genital and urinary tract, including the prostate.
The actual diagnosis of prostate cancer can only be made with a prostate biopsy .

Men At Higher Risk Of Prostate Cancer
Some men are at higher risk of prostate cancer than others. These are:
- black men
- men who have a family history of prostate cancer
The risk of prostate cancer also increases as men get older.
The evidence so far doesnt suggest that routinely screening these men would help prevent deaths from prostate cancer. In fact, it might lead to men having treatment for prostate cancer even though that cancer wouldnt have caused any problems or symptoms.
Screenings Can Lead To High Costs
The cost for a PSA test is fairly lowabout $40.
If your result is abnormal, the costs start adding up. Your doctor will usually refer you to a urologist for a biopsy. Costs may include:
- A consultation fee .
- An ultrasound fee .
- Additional professional fees .
- Biopsy fees .
If the biopsy causes problems, there are more costs. You might also have hospital costs.
Biopsy During Surgery To Treat Prostate Cancer
If there is more than a very small chance that the cancer might have spread , the surgeon may remove lymph nodes in the pelvis during the same operation as the removal of the prostate, which is known as a radical prostatectomy .
The lymph nodes and the prostate are then sent to the lab to be looked at. The lab results are usually available several days after surgery.
How To Get Tested
Samples used for PSA testing are collected by trained health care professionals at hospitals, labs, and other medical settings. Before getting tested, its best to talk to your doctor about the risks and benefits of PSA testing. You may be able to schedule your own PSA test at a clinic or laboratory without a doctors order. However, you will need a doctor to interpret the results of your test and recommend next steps.
Psa Levels By Age Chart
The main difference between the PSA scores of prostatitis and an enlarged prostate, compared to prostate cancer, is the ratio of free vs bound PSA within your test sample.
- Prostate Cancer will have a higher bound PSA ratio.
- An enlarged prostate and prostatitis will have a higher free PSA ratio.
- If your free PSA results are less than 25%, your risk for developing prostate cancer is between 10% to 20%.
- If your free PSA results are less than 10%, your risk for developing prostate cancer jumps to around 50%.
What Is Screening For Prostate Cancer
Some men get a PSA test to screen for prostate cancer. Talk to your doctor, learn what is involved, and decide if a PSA test is right for you.
Cancer screeningexternal icon means looking for cancer before it causes symptoms. The goal of screening for prostate cancer is to find cancers that may be at high risk for spreading if not treated, and to find them early before they spread.
There is no standard test to screen for prostate cancer. Two tests that are commonly used to screen for prostate cancer are described below.
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.
Experts In Urology Care
If you are experiencing symptoms consistent with urinary issues, we urge you to complete our urologic cancer risk assessment form.
Not everyone should get a PSA test. Why? Because many men in this country are treated for low-risk prostate cancer that is discovered through the PSA test, even when it is unlikely that the disease will ever cause symptoms or lead to death. And treatment is associated with significant side effects, including impotence and incontinence . So a PSA test is recommended only for men who might be at greater risk for dying of prostate cancer for example, younger men with a family history of prostate cancer or African-American men.
To avoid the risks of over-treatment, Roswell Park follows the guidelines established by the National Comprehensive Cancer Network . The NCCN brings together world-renowned experts from 30 of the nations top cancer centers to write guidelines that specify the best ways of preventing, detecting and treating cancer. The guidelines are updated at least every year, on the basis of the latest research.
Michael Kuettel, MD, PhD, MBA, Chair of Roswell Park’s Department of Radiation Medicine, serves on the NCCN Prostate Cancer Panel.
The NCCN recommends that only men in these categories receive a PSA test for early detection of prostate cancer:
Why A Psa Test Is Done
A PSA test may be done to:
- help find prostate cancer early in men who dont have any signs or symptoms of the disease
- check for cancer in men who have signs or symptoms of prostate cancer
- confirm a diagnosis when other tests suggest prostate cancer
- predict a prognosis for prostate cancer
- predict if cancer has spread outside the prostate
- plan treatment for prostate cancer
- monitor men with prostate cancer who are being treated with active surveillance
- find out if cancer treatments are working
- find out if cancer has come back after treatment
A PSA test is often used together with a digital rectal exam to increase the chance of finding prostate cancer early when it is easier to treat. Using these tests together is better than using either test alone.
What Is A Normal Psa Test Result
There is no specific normal or abnormal level of PSA in the blood, and levels may vary over time in the same man. In the past, most doctors considered PSA levels of 4.0 ng/mL and lower as normal. Therefore, if a man had a PSA level above 4.0 ng/mL, doctors would often recommend a prostate biopsy to determine whether prostate cancer was present.
However, more recent studies have shown that some men with PSA levels below 4.0 ng/mL have prostate cancer and that many men with higher levels do not have prostate cancer . In addition, various factors can cause a mans PSA level to fluctuate. For example, a mans PSA level often rises if he has prostatitis or a urinary tract infection. Prostate biopsies and prostate surgery also increase PSA level. Conversely, some drugsincluding finasteride and dutasteride , which are used to treat lower a mans PSA level. PSA level may also vary somewhat across testing laboratories.
Another complicating factor is that studies to establish the normal range of PSA levels have been conducted primarily in populations of White men. Although expert opinions vary, there is no clear consensus regarding the optimal PSA threshold for recommending a prostate biopsy for men of any racial or ethnic group.
In general, however, the higher a mans PSA level, the more likely it is that he has prostate cancer. Moreover, a continuous rise in a mans PSA level over time may also be a sign of prostate cancer.
New Blood Test Improves Prostate Cancer Screening
- Karolinska Institutet
- Researchers recently reported that magnetic resonance imaging could reduce overdiagnoses and thereby improve prostate cancer screening. Now, the same research group shows that the addition of a novel blood test, the Stockholm3 test, can reduce the number of MRIs performed by a third while further preventing the detection of minor, low-risk tumors.
Researchers at Karolinska Institutet in Sweden recently reported that magnetic resonance imaging could reduce overdiagnoses and thereby improve prostate cancer screening. Now, the same research group has published a study in The Lancet Oncology, which shows that the addition of a novel blood test, the Stockholm3 test, can reduce the number of MRIs performed by a third while further preventing the detection of minor, low-risk tumours.
“Overall, our studies show that we have identified the tools needed to be able to carry out effective and safe screening for prostate cancer. After many years of debate and research, it feels fantastic to be able to present knowledge that can improve healthcare for men,” says Tobias Nordström, associate professor of urology at the Department of Clinical Sciences, Danderyd Hospital at Karolinska Institutet, who is responsible for the STHLM3MRI study.
Henrik Grönberg, Martin Eklund and Tobias Nordström are partners of the company A3P Biomedical AB, which holds the development rights of the Stockholm3 test.
New Blood Test May Detect Aggressive Prostate Cancer
A new blood test has been found to accurately detect the presence of aggressive prostate cancer, according to research by Queen Mary University of London.

Prostate cancer is currently detected using a blood test that measures PSA levels. Although it provides early diagnosis, 75% of all PSA positive results ending up with negative biopsies that do not find cancer.
The study, published in the Journal of Urology, looked at the use of the CTC test in almost 100 pre-biopsy patients and over 150 newly diagnosed prostate cancer patients at St Bartholomew’s Hospital in London.
The research team found that the presence of CTCs in pre-biopsy blood samples was indicative of the presence of aggressive prostate cancer, and efficiently and non-invasively predicted the later outcome of biopsy results.
When the CTC tests were used in combination with the current PSA test, it was able to predict the presence of aggressive prostate cancer in other biopsies with over 90% accuracy.
The test could also show how aggressive the cancer is. Focusing on more aggressive prostate cancer may reduce overtreatment and unnecessary biopsies for benign and non-aggressive conditions.
Due to the small sample size, the findings will need to be validated by further studies. However, researchers said the CTC test could be available on the NHS in as little as three years if successful.
How Fast And Where Does Prostate Cancer Spread
Like other cancers, prostate cancer can spread from the site of where it first started to other sites of the body. Once it spreads, the disease may still respond to the treatment, but typically it is now no longer to be cured. Bones, liver, and lungs are the most common sites for prostate cancer metastasis. How do you know that it has spread? And how fast this metastasis?
Since the early detection of the disease is very crucial for the prognosis and outlook of patients , its very important to diagnose the disease as early as possible.
In the U.S, the number of men diagnosed with the disease at later stages decreases drastically due to the implementation of PSA screening test .
The PSA test is also recommended in other countries . However whether this test is necessary for all men is debatable.
For those who eventually dont have prostate cancer in their life, the choice to take the test may put them at high risk of getting over-diagnosis, making anxiety more likely.
Therefore, some experts agree that the screening prostate cancer test is more recommended for those who have some /many risk factors of the disease. For more advice, consult more with your GP!
How prostate cancer is diagnosed?
There are several procedures and tests that need to be performed by doctors before making diagnosis. These may include :
How Is A Digital Rectal Exam Performed
A DRE is a physical exam of the prostate. The health care provider will ask the patient to bend over a table or lie on his side while holding his knees close to his chest. The health care provider slides a gloved, lubricated finger into the rectum and feels the part of the prostate that lies next to it. The DRE may be slightly uncomfortable, but it is brief. This exam reveals whether the prostate has any abnormalities that require more testing. If an infection is suspected, the health care provider might massage the prostate during the DRE to obtain fluid to examine with a microscope. This exam is usually done first. Many health care providers perform a DRE as part of a routine physical exam for men age 50 or older, some even at age 40, whether or not the man has urinary problems.
Screening Tests For Prostate Cancer
Screening is testing to find cancer in people before they have symptoms. Its not clear, however, if the benefits of prostate cancer screening outweigh the risks for most men. Still, after discussing the pros and cons of screening with their doctors, some men might reasonably choose to be screened.
The screening tests discussed here are used to look for possible signs of prostate cancer. But these tests cant tell for sure if you have cancer. If the result of one of these tests is abnormal, you will probably need a prostate biopsy to know for sure if you have cancer.
Prostate Cancer: Advancements In Screenings
Dr. Christian Paul Pavlovich
You may know thatprostate canceris one of the most common cancer types in men. The good news is that thereare many treatment and management options, even if the cancer is caught ata later stage.
What you may not know: There are several options when it comes toprostate cancer screening. After considering multiple factors, your doctor may recommend theprostate-specific antigen test, and/or one of the newer screeningtests that are now available.
Johns Hopkins urologistChristian Pavlovich, M.D., explains what you should know.
Getting A Prostate Biopsy
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.
For more details on the prostate biopsy and how it is done, see Tests to Diagnose and Stage Prostate Cancer.
For more information about the possible results of a prostate biopsy, see the Prostate Pathology section of our website.
Determining Whether Prostate Cancer Is Aggressive
If a biopsy sample is found to contain cancer, the pathologist analyzing the specimen takes a deeper look at the cancer cells to determine how aggressive the disease is likely to be.
If the cancer cells appear significantly abnormal and dissimilar from healthy cells under a microscope, the cancer is considered more aggressive and expected to advance quickly. Conversely, cancer cells that look relatively similar to healthy cells indicate that its less aggressive and may not spread as fast.
Prostate cancers are assigned a Gleason score depending on how abnormal the cells look..
Gleason score: Gleason scores range from 2 to 10, going from least to most aggressive prostate cancers.
There are different types of cancer cells in a prostate tumor, so the final Gleason score is determined by adding the scores of the two main areas of the tumor.
First, the primary part of the tumor is assigned a number between 1 and 5. Lower numbers indicate that the cells appear relatively similar to healthy cells, while higher numbers show that the cells are abnormal-looking. Then, another number between 1 and 5 is assigned to describe the second most prevalent area of the tumor.
Finally, the two numbers assigned to the different parts of the prostate tumor are added. So, if most of the tumor is given a 4, and some of the tumor is more aggressive and given a 5, the final Gleason score would be 9.
There are many biomarker tests, including:
Is A Prostate Biopsy Painful
Chances of feeling any significant pain during a prostate biopsy are generally low, because your doctor will numb the area with an anesthetic shot.
However, you may feel some pain after the procedure, especially when sitting. Pain may occur in the area between the anus and scrotum and can last for a day or two. Your doctor may prescribe pain medications and suggest that you take it easy for a few days after the procedure.
What The Results Mean
PSA levels depend on a mans age. As men get older, their PSA levels naturally go up, but PSA can go up and down for many reasons. Doctors have a hard time agreeing on what is a normal PSA level. But some researchers use a cut-off PSA level of around 3 ng/mL to help them decide which men have the greatest risk of developing prostate cancer. Its important for you to discuss your PSA level result and what it means for your risk of prostate cancer with your doctor. Your doctor will help you determine your risk of prostate cancer in relation to your age, family history and other personal information.
A higher than normal PSA level doesnt always mean that a man has prostate cancer. High PSA levels can also be caused by:
- an enlarged prostate due to benign prostatic hyperplasia
- an inflamed or infected prostate
- a urinary tract infection
- a recent medical test or procedure on the prostate, such as a transrectal ultrasound or biopsy
- a urinary catheter
Psa Level Risk Analysis
- of men with a PSA level less than 4 ng/ml go on to develop prostate cancer.
- of men with PSA levels between 4 10 ng/ml have shown to develop prostate cancer.
- 50% 65% of men with psa scores over 10 ng/ml develop prostate cancer.
An important part of the your results is finding both the;
1. Total amount of PSA in your blood.
2. Ratio of free vs bound PSA.
What Is The Psa Test
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 a mans 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 men with prostate cancer, and the PSA test was originally approved by the US Food and Drug Administration in 1986 to monitor the progression of prostate cancer in men who had already been diagnosed with the disease. In 1994, FDA approved the use of the PSA test in conjunction with a digital rectal exam to test asymptomatic men for prostate cancer. Men who report prostate symptoms often undergo PSA testing to help doctors determine the nature of the problem.
In addition to prostate cancer, a number of benign conditions can cause a mans PSA level to rise. The most frequent benign prostate conditions that cause an elevation in PSA level are prostatitis and benign prostatic hyperplasia . There is no evidence that prostatitis or BPH leads to prostate cancer, but it is possible for a man to have one or both of these conditions and to develop prostate cancer as well.
