How Is The Psa Test Used In Men Who Have Been Treated For Prostate Cancer
The PSA test is often used to monitor patients who have a history of 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 other clinical signs and symptoms of prostate cancer recurrence.
However, a single elevated PSA measurement in a patient who has a history of prostate cancer does not always mean that the cancer has come back. A man who has been treated for prostate cancer should discuss an elevated PSA level with his 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.
What Are Normal Psa Levels
Thereâs no such thing as a normal PSA for any man at any given age, but most men with prostate cancer have a higher than normal level. In general:
If your PSA results are in the borderline range , the % free PSA can be useful in helping distinguish between prostate cancer or benign prostatic hyperplasia . The pattern is the opposite of that seen with PSA in that a high % free PSAâabove 20%âpoints to BPH, while a %- free PSA less than 10% indicates a greater likelihood of cancer.
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.

Changes To Psa Screening Recommendations
In many cases, men with increased PSA levels do not have cancer, and these men suffer a great deal of anxiety and financial cost as a result of unnecessary biopsies. Additionally, the biopsy itself is associated with a small risk of bleeding and infection. Also, low PSA levels do not necessarily indicate the absence of cancer.
In May 2018, the U.S. Preventive Services Task Force updated its recommendation for PSA testing to screen for prostate cancer. Both the USPSTF and the American Academy of Family Physicians recommend that men between the ages of 55 and 69 years should make individual decisions about screening only after a discussion with their physician about the risks and benefits of screening. For men over age 70 years, PSA tests are not recommended, as the risk of the disease itself does not outweigh the risks of testing. There are no specific screening recommendations for men at higher risk of prostate cancer since there is insufficient evidence of the mortality benefits of screening. Many physicians will recommend regular testing in high-risk men only after discussing the associated risks and benefits. For those who decide to undergo screening, they should not be screened more frequently than every 2 years.
If you have questions about prostate cancer, risk factors, and screening recommendations, consult a trusted healthcare provider. Pharmacists can consult on the treatment of prostate cancer and the associated side effects.
Noncancerous Prostatic Disease And Urologic Manipulation
The serum PSA level can also be altered by noncancerous prostatic disease and urologic manipulations. Elevation of PSA levels has been demonstrated in acute prostatitis, subclinical or chronic prostatitis, and urinary retention. Nadler et al reported that serum PSA levels higher than 4.0 ng/mL in 148 men with subclinical prostatitis could be attributed to their disease because all these men had negative findings from biopsies repeated on multiple occasions.
No significant change occurs in the PSA level after a digital rectal examination , but a vigorous prostate massage can produce a short-term 2-fold increase. Cystoscopy, urethral catheterization, and transrectal ultrasonography of the prostate do not tend to elevate the PSA level. Needle biopsy of the prostate raises the PSA level by a median of 7.9 ng/mL within 5 minutes after the biopsy, and this level persists for 24 hours.
The time it takes for PSA to return to baseline levels depends on the precipitating event and the half-life . After a biopsy, 2 to 4 weeks may elapse before the PSA returns to its original level. If an infection occurs as a result of the biopsy, the return to baseline levels may take longer. After ejaculation, PSA levels have been reported to return to their original levels within 48 hours, whereas fPSA returns to baseline at 6 hours because of its shorter half-life .

What Are Some Of The Limitations And Potential Harms Of The Psa Test For Prostate Cancer Screening
Detecting prostate cancer early may not reduce the chance of dying from prostate cancer. When used in screening, the PSA test can help detect small tumors that do not cause symptoms. Finding a small tumor, however, may not necessarily reduce a mans chance of dying from prostate cancer. Many tumors found through PSA testing grow so slowly that they are unlikely to threaten a mans life. Detecting tumors that are not life-threatening
that requires treatment.
What Is A High Psa Level
The PSA test alone cant diagnose any disease. As discussed, elevated PSA levels do not always mean that you have prostate cancer or any other prostate problem.
Many factors can affect your PSA levels so that the doctor wont consider your PSA level on its own.
There is no specific normal or abnormal level of PSA. Factors such as age and ethnicity make it hard for researchers to establish a normal range.
However, most doctors consider PSA levels of 4.0 ng/ml as high and would often recommend a prostate biopsy. One study shows that men with this level of PSA often have prostate cancer.
Low PSA levels also dont always mean that you dont have prostate cancer. Studies show that some men with a PSA below 4.0 ng/ml do have prostate cancer.

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.

What Happens If My Psa Comes Back High
Should your PSA level return higher than expected or above the normal physiologic range based on your age, the first step will likely be to draw a follow-up PSA. If the repeat PSA is lower, the initial elevation may have been temporary and associated with something other than prostate cancer. If the repeat PSA remains high, Dr. Kasraeian may recommend further studies, including an MRI, prostate biopsy, or another advanced diagnostic test to rule out prostate cancer. While all patients are monitored closely, patients who receive an elevated PSA result can expect to have PSAs drawn more frequently for a period of time.
What Should I Expect If Im Told I Have Elevated Psa
If your provider finds an elevated PSA level, youll have repeat tests to check your prostate. Many men with elevated PSA levels even those who have prostate cancer live long, healthy lives. Prostate cancer may not need treatment, depending on how slowly the tumor is growing. Keep up with your regular appointments and tests so your care team can keep tabs on your health.

Problems With The Psa Test
There are reasons doctors donât agree on whether you need this test:
- Finding prostate cancer early doesnât always protect you. The PSA test often finds small, slow-growing tumors that arenât life-threatening. Treating them anyway, whether itâs with surgery or radiation, can expose you to harmful side effects and complications. Also, finding cancer early may not help if you have an aggressive tumor or if it spread to distant body parts before you found it.
- The results arenât always accurate. If you have a high level but you donât have cancer, the test results can create a lot of worry and lead to medical procedures you donât need. A negative result if you really do have cancer can prevent you from getting treatment you do need.
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.

If I Choose Psa Testing What Are The Next Steps If You Have A Raised Psa Level
Instead of quickly jumping to surgery and drugs for a solution, there is another option: active surveillance.
Active surveillance is a non-invasive approach to prostate cancer treatment.
Active surveillance is the better option if your cancer shows all signs of being the good kind, i.e. slow-growing, low volume, and not aggressive. In this case, you can treat it without drugs, radiation, or surgery.
A benefit of monitoring low-risk cancer is that you might avoid having unnecessary surgery.
In fact, one study of men undergoing active surveillance found that, 15 years later, less than 1% of men developed metastatic disease. There are also other natural ways to treat prostate cancer.
Watchful waiting is also another option. Watchful waiting is usually used by men experiencing other health problems, who may be unable to handle surgery or radiotherapy.
It involves fewer tests than active surveillance and is less intensive, more often than not taking place at the GP surgery than a hospital.
If you do have treatment in the future, it will aim to control the cancer and manage any symptoms, rather than to cure it.
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. Thatâs 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.

Following Psa Levels During And After Prostate Cancer Treatment
A mans prostate-specific antigen blood level is often a good indicator of how effective treatment is or has been. Generally speaking, your PSA level should get very low after treatment. But PSA results arent always reliable, and sometimes doctors arent sure what they mean.
Before starting treatment, you might want to ask your doctor what he or she expects your PSA level to be during and after treatment, and what levels might cause concern. Its important to know that the PSA level is only one part of the overall picture. Other factors can also play a role in determining if cancer is still there, if it is growing, or if it has come back.
Its also important to know that PSA levels can sometimes fluctuate a bit on their own, even during or after treatment, so they may not always be a sign of what is actually happening with your cancer. Understandably, many men being treated for prostate cancer are very concerned about even very small changes in their PSA levels. The PSA level is an important tool to monitor the cancer, but not every rise in PSA means that the cancer is growing and requires treatment right away. To help limit unnecessary anxiety, be sure you understand what change in your PSA level might concern your doctor.
Is Prostatitis Cancer
No. Prostatitis is a benign ailment, which, while not always curable, is almost always treatable with antibiotics. Occasionally, inflammation due to prostatitis can raise your PSA level . However, it does not lead to cancer.
Prostate cancer is believed to be due to a combination of factors including diet, lifestyle, genetics, and environmental exposures. There is, however, a question as to whether continued inflammation of the prostate may lead to the eventual development of prostate cancer, and studies are being done to determine if reducing inflammation can prevent prostate cancer.

When To See A Doctor
Some of the first symptoms of patients who have an elevated PSA level is difficult or painful urination, pain in the abdomen or pelvic area, and a frequent urge to urinate. These symptoms can be signs of BPH, prostatitis, prostate cancer, and kidney stonesall of which require different treatment. If you are experiencing any of these symptoms, it is important to talk with your doctor. Your doctor will be able to help determine the cause of your problems and provide an individualized treatment plan.
How Does Bph Occur
The prostate goes through two main periods of growth. In early puberty, the prostate doubles in size. Then, around age 25, the prostate begins to grow again and continues to grow throughout most of a man’s life.
The continuing enlargement of the prostate does not usually cause problems until later in life. However, the second period of growth may, many years later, result in BPH. According to the National Institute of Diabetes and Digestive and Kidney Diseases:
BPH rarely causes symptoms before age 40.
More than half of men in their 60s have some symptoms of BPH.
As many as 90 percent of men in their 70s and 80s have some symptoms of BPH.

Repeating The Psa Test
A mans blood PSA level can vary over time , so some doctors recommend repeating the test after a month or so if the initial PSA result is abnormal. This is most likely to be a reasonable option if the PSA level is on the lower end of the borderline range . For higher PSA levels, doctors are more likely to recommend getting other tests, or going straight to a prostate biopsy.
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.
