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.
How Are Researchers Trying To Improve The Psa Test
Scientists are investigating ways to improve the PSA test to give doctors the ability to better distinguish cancerous from benign conditions and slow-growing cancers from fast-growing, potentially lethal cancers. None has been proven to decrease the risk of death from prostate cancer. Some of the methods being studied include:
What Should You Know About Psa Levels
Under normal circumstances, the serum secretions of PSA should stay under 4 nanograms per milliliter . People who have prostate malignancy usually have high PSA levels, but low or normal PSA doesnt always mean that the person is cancer-free. A smaller number of men with prostate cancer have low or normal PSA levels. This suggests that PSA test by itself is not a confirmatory test but can help in identifying who might be at risk of developing the cancer or has developed the malignancy.
Usually PSA test is preceded or coupled by DRE , in which the examiner inserts the finger in patients rectum to check for the consistency or edges of prostate gland. At risk patients with abnormal findings on the DRE and high PSA levels are subjected to biopsy to ascertain the cause and confirm the diagnosis. It is imperative to mention that False-Positives are common.
High PSA Levels without Prostate Cancer:
Testing errors such as mishandling of sample, measuring inconsistency, lifestyle choices and overall physical health can alter with PSA levels. Following are some physiological causes of high PSA levels.

The prostate is a walnut-sized gland found between the bladder and the rectum in males. Its primary job is to produce seminal fluid. The prostate creates a protein, the prostate-specific antigen, or PSA. A PSA screening test is a blood test approved by the FDA in 1994 to measure the levels of PSA in a mans blood.
Small amounts of PSA ordinarily circulate in the bloodstream and can be measured by a PSA test to monitor the health of the prostate. This test is intended to screen for prostate cancer, find other prostate-related conditions, or monitor PSA levels in those in treatment for prostate cancer. This is a simple blood test which reports PSA levels as nanograms of PSA per milliliter of blood.
How Often Does A Prostate Specific Antigen Increase
Some research shows that PSA velocity that rises quickly can help doctors diagnose prostate cancer. PSA doubling time measures the time it takes the PSA level to double. The result is calculated in time. For example, a PSA doubling time of 3 years means that, on average, the PSA level doubles every 3 years.

Normal Psa Levels By Age Chart
We mentioned earlier in this article that PSA levels increase with age due to age related growth of the prostate gland. A doctor will therefore take into account an age-adjusted PSA level when discussing your prostate health:

Elevated Psa Level Causes
Elevated PSA Level Causes
Prostate specific antigen is a protein that is produced by the prostate gland. Rising levels of PSA in the bloodstream can be an early sign of prostate problems, including prostate cancer. But there are also many non-cancerous reasons for elevated PSA levels. Infection, inflammation, and injury can all trigger a rise in PSA.
Possible causes for elevated PSA level include:
The likelihood of developing BPH increases as men age. According to the American Urological Association, BPH affects about half of men in their fifties and sixties and up to 90% of men over age eighty. The larger the prostate, the greater the chance a PSA elevation may be due to a benign condition like BPH and not prostate cancer.
What Is The Test To See If I Have Elevated Psa
Healthcare providers use a blood test to measure PSA levels.
You may have a digital rectal exam together with a PSA test to check for signs of prostate cancer. During a DRE, your provider inserts a gloved finger into the rectum to check for bumps or other irregularities.
Depending on the results of your initial test, your provider may want you to repeat the test. PSA levels can change. A second test gives your provider more details about your prostate health.

What Research Has Been Done To Study Prostate Cancer Screening
Several randomized clinical 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 DRE 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 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 Test Is Often Not Needed
Most men with high PSAs dont have prostate cancer. Their high PSAs might be due to:
- An enlarged prostate gland.
- Recent sexual activity.
- A recent, long bike ride.
Up to 25% of men with high PSAs may have prostate cancer, depending on age and PSA level. But most of these cancers do not cause problems. It is common for older men to have some cancer cells in their prostate glands. These cancers are usually slow to grow. They are not likely to spread beyond the prostate. They usually dont cause symptoms, or death.
Studies show that routine PSA tests of 1,000 men ages 55 to 69 prevent one prostate cancer death. But the PSA also has risks.

Psa Testing For Detection Of Prostate Cancer
The introduction of prostate-specific antigen testing into clinical practice has greatly increased the detection of localized prostate cancer and, by doing so, has decreased the diagnosis of regional and metastatic disease. PSA testing has had such a profound clinical effect that questions have arisen regarding the significance of the cancers that are being detected.
Stage, grade, tumor volume, and PSA testing are used to determine whether a prostate cancer is clinically significant or insignificant. However, there is no generally accepted precise definition for this distinction.
The goal of early detection of prostate cancer is to identify clinically significant cancers at a time when treatment is most likely to be effective. The risk of death from prostate cancer is significant in those with moderate- to high-grade tumors. This is especially true in younger men. Long-term survival is compromised when the cancer has spread beyond the confines of the prostate, into the regional lymph nodes, and to distant sites.
Several studies have shown that with a PSA cutoff of 4.0 ng/mL, clinically insignificant cancers are detected in fewer than 20% of men, but nearly 50% of all the cancers detected because of an elevated PSA level are localized, and these patients are candidates for potentially curative therapy. Only a small proportion of prostate cancers detected by PSA testing and treated with radical prostatectomy are low-volume and low-grade tumors.

Prostatitis: A Common Problem In Men Under 50
“The PSA test is a good screening tool for prostate cancer, but it is not very specific,” says Erik P. Castle, MD, a urologist and researcher at the Mayo Clinic in Phoenix, Arizona. “Common causes of inflammation in the gland, called prostatitis, can cause high PSA levels.”
Prostatitis is the most common prostate problem for men younger than 50.
Prostatitis caused by bacteria can be treated with antibiotics. Another, more common type of prostatitis, called nonbacterial prostatitis, can be harder to treat and may last a long time.

What Causes An Elevated Psa Level
Prostate cancer is the main cause of an elevated PSA level. But PSA levels increase with age and can reflect different prostate conditions. Other factors that may raise a persons PSA level include:
- Prostate enlargement and inflammation .
- Urinary tract infection.
- Urinary catheter placement.
Your healthcare provider will also consider whether your medications affect PSA levels. For example, 5-alpha reductase blockers treat enlarged prostates and will lower PSA levels.
What’s A Raised Psa Level
The amount of PSA in your blood is measured in nanograms of PSA per millilitre of blood .
If you’re aged 50 to 69, raised PSA is 3ng/ml or higher.
A raised PSA level in your blood may be a sign of prostate cancer, but it can also be a sign of another condition that’s not cancer, such as:

What Does Psa Score Indicate Cancer
Low PSA level below 4.0 ng/ml does not indicate the presence of prostate cancer or not. High PSA levels over 10.0 ng/ml is an indicator of the presence of prostate cancer with 50% chance according to ACS. A PSA level of 10-14 may be due to an inflamed prostate and not a cancer marker unless the biopsy results show other than that.
What Does An Elevated Psa Level Mean If Ive Had Prostate Cancer In The Past
If youve ever had treatment for prostate cancer, youll have regular PSA screenings for the rest of your life. An increasing PSA level may mean the cancer has returned. Your care team may use other tests, including imaging scans and biopsies, to check for signs of cancer. If cancer returns, your team will discuss your treatment options with you.

Changes In Your Psa Level
A PSA level that is in the normal range may nonetheless need clarification if recent blood tests show that it has increased. For instance, an annual PSA test may show that your PSA level has increased from 2 ng/mL to 3 ng/mL. Although your PSA level is under 4 ng/mL, and therefore within the normal range, the increase may have been caused by early-stage prostate cancer.
If your PSA level is already above 4 ng/ml and screening reveals another significant increase, then clarification is even more urgent. Thats why we recommend proactive PSA testing. That being said, regular PSA testing cannot provide a basis for diagnosing the cause of an elevated PSA level.
Is The Psa Test Recommended For Prostate Cancer Screening
MISHKANET.COM” alt=”Psa levels by age chart > MISHKANET.COM”> Until about 2008, some doctors and professional organizations encouraged yearly PSA screening for men beginning at age 50. Some organizations recommended that men who are at higher risk of prostate cancer, including African-American men and men whose father or brother had prostate cancer, begin screening at age 40 or 45. However, as more was learned about both the benefits and harms of prostate cancer screening, a number of organizations began to caution against routine population screening. Most organizations recommend that men who are considering PSA screening first discuss the risks and benefits with their doctors.
Currently, Medicare provides coverage for an annual PSA test for all Medicare-eligible men age 50 and older. Many private insurers cover PSA screening as well.

Causes Of High Psa Levels Without Prostate Cancer
PSA or prostatic specific antigen is a special protein that is secreted by prostate cells. The PSA test determines the serum levels of this protein in the blood. It has been observed that high PSA levels are usually suggestive of prostate disease but high levels of PSA doesnt always mean that the person is suffering from prostate cancer. High PSA levels that are caused by benign conditions returns to normal levels if inciting source is removed.
The Role Of A Psa Level As An Indicator
It is not possible to diagnose a specific prostate disease solely on the basis of a PSA test. PSA levels may increase as a result of malignant, acute or age-related changes in the prostate.
Some men may even have all three of the common diseases that affect the prostate, with each disease contributing variously to an elevated PSA level.
The PSA level may reflect all of the relevant changes in the prostate. It is regarded as conspicuous when it is elevated or when it fluctuates.
The PSA level is a good indicator and should only be regarded as an indicator. When taken alone, it offers no certainty as to any specific changes to the prostate and cannot be used as a basis for a diagnosis.
In contrast, an MRI scan of the prostate does provide a reliable basis for a diagnosis.
MRI scans generate hundreds of high-resolution, cross-sectional images of the prostate gland. These images can reveal any changes that may have occurred in the tissue. Using the latest technology and multi-parametric software, we at the ALTA Klinik can even detect very small, early-stage changes in the prostate.
