Medical Procedures Can Cause Psa To Rise
Anything that traumatically interferes with the architecture around the prostate gland can make PSA go up, says Dr. Milner. One of the most common causes of significantly high PSA from this type of trauma is the placing of a catheter into the bladder.
Another cause is a prostate or bladder exam that involves passing a scope or taking a biopsy.
Since it takes about two to three days for PSA to go down by half, you should wait two to three weeks after this type of trauma to do a PSA test, Milner says.

Pros And Cons Of The Psa Test
- it may reassure you if the test result is normal
- it can find early signs of cancer, meaning you can get treated early
- PSA testing may reduce your risk of dying if you do have cancer
- it can miss cancer and provide false reassurance
- it may lead to unnecessary worry and medical tests when there’s no cancer
- it cannot tell the difference between slow-growing and fast-growing cancers
- it may make you worry by finding a slow-growing cancer that may never cause any problems
Should I Get Screened For Prostate Cancer
This video helps men understand their prostate cancer screening options.
In 2018, the U.S. Preventive Services Task Force made the following recommendations about prostate cancer screeningexternal icon
- Men who are 55 to 69 years old should make individual decisions about being screened for prostate cancer with a prostate specific antigen test.
- Before making a decision, men should talk to their doctor about the benefits and harms of screening for prostate cancer, including the benefits and harms of other tests and treatment.
- Men who are 70 years old and older should not be screened for prostate cancer routinely.
This recommendation applies to men who
- Are at average risk for prostate cancer.
- Are at increased risk for prostate cancer.
Other organizations, like the American Urological Association,external icon the American Cancer Society,external icon and the American College of Physiciansexternal icon may have other recommendations.
Finding Prostate Cancer Early
There is no national screening program for the early detection of prostate cancer. Doctors have different opinions about whether all men without symptoms of prostate cancer should be tested.
There is concern that testing healthy men will cause unnecessary harm and lead to treatments that may not offer long-term benefits. Treatment for prostate cancer can leave men with side effects such as erectile dysfunction and continence issues, which can affect their quality of life.
Testing may identify fast-growing or aggressive cancers that have the potential to spread to other parts of the body and would benefit from treatment. It may also detect very slow-growing cancers that are unlikely to be harmful.
Weigh up all the risks and benefits before deciding whether to be tested for prostate cancer, particularly if you dont have symptoms. Talking to your doctor can help.
Urine Test May Spot Aggressive Prostate Cancer
THURSDAY, Nov. 4, 2021 — A urine test might one day be able to tell which prostate cancer patients need immediate treatment and which don’t, British researchers report.
“Prostate cancer can be divided into low and high risk — the low-risk men rarely require treatment, and the high-risk certainly do,” said study author Jeremy Clark, a senior research associate at Norwich Medical School at the University of East Anglia in Norfolk. “However, there is a third group, called intermediate risk, which falls between these extremes, and the treatment pathway for these men is less clear.”
Prostate cancer is common — over 40% of 50-year-old men will have prostate cancer — but not everyone is dying of it, so deciding which men to treat is not always easy, Clark said.
“We have developed a simple urine test that can measure the presence of aggressive cancer and also how much aggressive cancer is present,” he said.
“The test appears to be able to assess how much aggressive cancer is present in these intermediate-risk men, and so could be used to identify a group of intermediate-risk men that could avoid immediate treatment, which includes surgery and radiotherapy, and instead, these men could be monitored by active surveillance by being retested yearly to see if their disease is stable or not,” Clark said. “Around a quarter of the intermediate-risk men could fall into this group.”
The report was published Nov. 3 in the journal Life.

Advanced Genomic Testing For Prostate Cancer
The most common lab test for prostate cancer is advanced genomic testing, which examines a tumor to look for DNA alterations that may be driving the growth of the cancer. By identifying the mutations that occur in a cancer cells genome, doctors may get a clearer picture of the tumors behavior and be able to tailor a patients treatment based on the findings.
Psa Test For Prostate Cancer
The prostate gland makes a protein called prostate specific antigen . This protein helps to nourish sperm. Normally, only tiny amounts of it enter the bloodstream.
Cancer cells in the prostate interfere with proper functioning and can cause large amounts of PSA to enter the bloodstream. Therefore, when high levels of PSA are detected in the bloodstream, this may indicate cancer.
Early prostate cancer often has no symptoms. However, high PSA levels can occur five to 10 years before the onset of prostate cancer symptoms. In such circumstances, the PSA test can help to indicate the presence of cancer at an early stage.
Other tests are needed to confirm a diagnosis because an abnormal PSA test can be due to non-cancerous causes. Equally, it is possible for a man to have a normal PSA level when cancer is present.

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.

How Is Prostate Cancer Diagnosed
A biopsy is when a small piece of tissue is removed from the prostate and looked at under a microscope.
A biopsy is a procedure that can be used to diagnose prostate cancer. A biopsy is when a small piece of tissue is removed from the prostate and looked at under a microscope to see if there are cancer cells.
A Gleason score is determined when the biopsy tissue is looked at under the microscope. If there is a cancer, the score indicates how likely it is to spread. The score ranges from 2 to 10. The lower the score, the less likely it is that the cancer will spread.
A biopsy is the main tool for diagnosing prostate cancer, but a doctor can use other tools to help make sure the biopsy is made in the right place. For example, doctors may use transrectal ultrasound or magnetic resonance imaging to help guide the biopsy. With transrectal ultrasound, a probe the size of a finger is inserted into the rectum and high-energy sound waves are bounced off the prostate to create a picture of the prostate called a sonogram. MRI uses magnets and radio waves to produce images on a computer. MRI does not use any radiation.
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.

Prostate Cancer Urine Test
This test detects the gene PCA3 in your urine and can also help your doctorbetter assess your prostate cancer risk.
PCA3 is a prostate-specific noncoding RNA. Its a gene thats only in yourprostate. If the gene is overexpressed , then theres a greater chance you have prostate cancer.
Like PSA and PHI tests, this isnt definitive, either. But data suggestthat when cancer is present, the PCA3 will be positive 80 percent of thetime. This test can also help your doctor determine whether a biopsy isnecessary.
Both of these new tests are more accurate than the PSA test. Your doctormay recommend one or more than one, based on the specifics of your case.
Possible Harms From Treatment
The most common treatments for prostate cancer are surgery to remove the prostate and radiation therapy.
The most common harms from prostate cancer treatment are
- Urinary incontinence . About 1 out of every 5 men who have surgery to remove the prostate loses bladder control.
- Erectile dysfunction . About 2 out of every 3 men who have surgery to remove the prostate become impotent, and about half of men who receive radiation therapy become impotent.
- Bowel problems, including fecal incontinence and urgency . About 1 out of every 6 men who has radiation therapy has bowel problems.

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.

Can I Take The Test At Home
Although testing for PSA at home is uncommon, several at-home PSA tests are available. At-home PSA tests typically involve collecting samples of blood at home through a fingerstick and sending the samples into a laboratory for testing. When considering at-home PSA testing, its important to understand the potential harms of this test.
At-home testing may be less accurate than testing a sample taken from a vein. PSA testing can also show a higher result when cancer isnt present and can lead to additional diagnostic procedures. Because the role of PSA testing is highly individualized, its important to seek testing only under the care and guidance of a doctor.
Who Should Get A Digital Rectal Exam
Not all medical institutions agree on when men should begin screening for prostate cancer or even if a DRE should be part of the screening.
To help detect prostate cancer in its early stages, the American Cancer Society recommends that men talk to their doctors about the benefits, risks, and limitations of prostate cancer screening before deciding whether to be tested.
For most men at average risk, discussions about screening begin at age 50. However, some doctors recommend that men at higher risk of prostate cancer African-American men or men with a family history of prostate cancer start screening earlier.

Are There Any New Developments In The Treatment Of Prostate Cancer
Doctors often successfully treat prostate cancer. Sometimes, however, the disease returns . An FDA-approved radiotracer for PET/CT called Axumin® helps detect and locate cancer that recurs following radiation therapy or surgery.
Conventional imaging, such as MRI or ultrasound, cannot locate recurring prostate cancer when it is small. PET/CT with Axumin® can detect recurring cancer when PSA levels are low and when the cancer is small.
Identifying the exact location and extent of the disease at an early state is vital. It allows doctors to specifically target the cancer and limit exposure to healthy tissues.
Prostate-specific membrane antigen is a protein that helps develop prostate cancer. A PSMA scan uses PET imaging and a radiotracer to locate recurrent cancer. Doctors are studying Lutetium-177 PSMA therapy in clinical trials for use in treating prostate cancer. Neither of these procedures has FDA approval yet.

Prolaris Test For Prostate Cancer Risk Assessment
Am Fam Physician. 2019 Sep 1 100:311-312.
Prolaris is a genomic test that analyzes changes in 46 genes in prostate biopsy tissue. It generates a risk score to help predict the likelihood of disease progression in men with localized prostate cancer. Prolaris is intended to guide the decision regarding active surveillance without surgery or radiation for low- or intermediate-grade cancers vs. active treatment with immediate surgery or radiation therapy. The National Comprehensive Cancer Network guidelines recommend that physicians consider this test for patients with low-risk and favorable intermediate-risk disease and at least a 10-year life expectancy.1

What Do The Results Mean
PSA levels may be above the baseline for various reasons other than prostate cancer.
Other factors that can raise PSA levels include:
- older age
- an enlarged prostate â because of benign prostatic hyperplasia , for example
- prostatitis, which is inflammation and swelling of the prostate
Also, people with obesity may have lower PSA readings.
In addition, some medications may reduce PSA levels, including:
- 5-alpha reductase inhibitors, which can help treat BPH
- aspirin, which some people take regularly as a blood thinner
- statins, which help manage cholesterol levels
- thiazide diuretics, a kind of water pill that can help reduce high blood pressure
Some herbal medicines and supplements can also lower PSA levels. Tell the doctor about any medications and supplements before undergoing the test.
High PSA levels alone do not indicate cancer. However, if a DRE also reveals changes, a doctor may recommend a biopsy for a more accurate result.
The PCA3 is another test for prostate cancer that doctors use in some circumstances. Find out more.
Why Test For Prostate Cancer
Prostate cancer affects 1 in 7 men. Certain men are at higher risk for prostate cancer because of their family history breast cancer and ovarian cancer in mothers and sisters can also put men at increased risk for prostate cancer.
It is important that all men over age 40 who have symptoms that can be caused by prostate cancer are tested for prostate cancer. These symptoms can be caused by many other conditions but it is important to test for prostate cancer in order not to miss it.

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.
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.
