What Is The Prostate
The prostate is a small gland in the pelvis, found only in men.
About the size of a satsuma, it’s located between the penis and the bladder, and surrounds the urethra.
The main function of the prostate is to produce a thick white fluid that creates semen when mixed with the sperm produced by the testicles.
Which Test Is Done For Screening Of Prostate Cancer
There is no single, standard test for screening for prostate cancer. The screening commonly is done with the prostate-specific antigen blood test. This test measures the blood levels of PSA, which is a substance made by the prostate. An ultrasonography may be done if PSA values are dubious. Another commonly used test that may be done for screening is the digital rectal examination or DRE. During a DRE, the doctor inserts a gloved, lubricated finger into a mans rectum and feels the prostate for anything abnormal, such as cancer.
Can I Check For Prostate Cancer At Home
It is strongly advised under any circumstances not to self-examine for prostate cancer at home either by yourself or with a partner. Not only does it take a skilled professional to assess how the prostate feels to make an accurate determination of overall prostate health, self-examinations have the potential to cause injury.
âSince the prostate is an internal gland, itâs extremely important that only licensed medical professionals conduct the exam. At-home self-exams should not be administered in order to avoid injury or self-harm. Regular screening is important for prostate cancer, as the disease often does not present symptoms until it is too late. Talk to your doctor about making sure you receive a regular DRE check-up at each visit.â
While actually screening yourself for prostate cancer at home is ill advised, you can still monitor your risk factors for prostate cancer between yearly check-ups, like practicing a healthy diet and exercising regularly.

Who Should Think About Getting Tested
To find out if you have a genetic mutation linked to prostate cancer, you can take a simple blood or saliva test. If your urologist suggests genetic testing, they may send you to a genetic counselor. They may also order the test and then send you to a genetic counselor if the results are positive or uncertain.
There are two groups of men who may want to think about being tested for prostate cancer genes, Dr. Morgan said.
The first group are men with localized prostate cancer who have a family history of breast, colon, ovarian, pancreatic or prostate cancer.
Doctors may decide whether to suggest genetic testing based in part on his Gleason score-a grading system that describes how aggressive the cancer is.
The National Comprehensive Cancer Network, a not-for-profit group representing many leading cancer centers, suggests a man should think about genetic testing if he has a Gleason score of seven or higher and at least one of the following:
- At least one close blood relative with breast or ovarian cancer at age 50 or younger, or
- A least two family members with breast, ovarian or prostate cancers at any age.
What If A Screening Test Shows An Elevated Psa Level
If a man who has no symptoms of prostate cancer chooses to undergo prostate cancer screening and is found to have an elevated PSA level, the doctor may recommend another PSA test to confirm the original finding. If the PSA level is still high, the doctor may recommend that the man continue with PSA tests and DREs at regular intervals to watch for any changes over time.
If a mans PSA level continues to rise or if a suspicious lump is detected during a DRE, the doctor may recommend additional tests to determine the nature of the problem. A urine test may be recommended to check for a urinary tract infection. The doctor may also recommend imaging tests, such as a transrectal ultrasound, x-rays, or cystoscopy.
If prostate cancer is suspected, the doctor will recommend a prostate biopsy. During this procedure, multiple samples of prostate tissue are collected by inserting hollow needles into the prostate and then withdrawing them. Most often, the needles are inserted through the wall of the rectum . A pathologist then examines the collected tissue under a microscope. The doctor may use ultrasound to view the prostate during the biopsy, but ultrasound cannot be used alone to diagnose prostate cancer.

Lymph Node Biopsy As A Separate Procedure
A lymph node biopsy is rarely done as a separate procedure. Its sometimes used when a radical prostatectomy isnt planned , but when its still important to know if the lymph nodes contain cancer.
Most often, this is done as a needle biopsy. To do this, the doctor uses an image to guide a long, hollow needle through the skin in the lower abdomen and into an enlarged node. The skin is numbed with local anesthesia before the needle is inserted to take a small tissue sample. The sample is then sent to the lab and looked at for cancer cells.
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 Often Should Men Have A Prostate Screening
A prostate screening is extremely important to have regularly. Because, without them, a mans health is at a high risk of developing prostate cancer. Knowing how often prostate screenings should be had can be helpful to those men who are not sure.
A mans health is just as important to maintain as a womans. But most people are under the assumption that womens health needs more attention. However, that is not true. Men are at risk of developing prostate cancer, and it can become very problematic if not addressed.
Keep reading to find out how often a man should have a prostate screening.

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 Tests Do Health Care Professionals Use To Diagnose Prostate Cancer
The diagnosis of prostate cancer ultimately is based on the pathologists review of tissue removed at the time of the prostate biopsy. An abnormal PSA and/or abnormal digital rectal examination often are present and are the indications for the prostate biopsy.
Digital rectal examination : As part of a physical examination, your doctor inserts a gloved and lubricated finger into your rectum and feels toward the front of your body. The prostate gland is a walnut or larger-sized gland immediately in front of the rectum, and beneath your bladder. The back portion of the prostate gland can be felt in this manner. Findings on this exam are compared to notes about the patients prior digital rectal examinations.
The exam is usually brief, and most find it uncomfortable due to the pressure used to adequately examine the prostate gland. Findings such as abnormal size, lumps, or nodules may indicate prostate cancer.
The National Comprehensive Cancer Network notes that a DRE should not be used as a stand-alone test for the detection of prostate cancer but should be performed in men with an elevated PSA. The NCCN also notes that DRE may be considered as a baseline test in all patients, as it may help identify high-grade cancers associated with a normal PSA.
If the PSA level is elevated or has increased significantly over time, further testing may be needed to rule out prostate cancer.

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.

What Is Prostate Cancer
Prostate cancer is the abnormal growth of cells in the tissues of the prostate gland. It is the second most common cancer in men. Most men who get it are older than 65.
Early prostate cancer usually doesn’t cause symptoms. When prostate cancer is found before it has spread outside the prostate gland, a man’s options include active surveillance, surgery to remove the prostate, or radiation. If a prostate cancer grows or spreads, symptoms may develop, including urinary problems and bone pain.
Many prostate cancers grow slowly. This means that many men with prostate cancer will die of something else before their prostate cancer advances enough to cause any problems. With faster-growing prostate cancers, finding the cancer early may not help you live longer. Some prostate cancers will be fatal no matter when they’re found or how they are treated.

Imaging Tests For Prostate Cancer
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:
Craig Melvin And Al Roker Premiere ‘get Checked’ Psa
Dr. Matthew Rettig, the medical director of the Prostate Cancer Program at the Institute of Urologic Oncology at UCLA in California, said that even if screenings aren’t performed right away, men should at least start talking about them with their doctors early in life.
“I think I would have that conversation fairly early on in life, maybe even in 30s or 40s, about when to initiate screening,” said Retting. “I think that would be most important for patients who are at high risk for prostate cancer and high risk for early onset of prostate cancer. Those are the types of patients that probably ought to have the discussion and make a decision about when to start screening at a relatively young age.”

When Should You Be Screened For Prostate Cancer
A prostate cancer diagnosis may involve PSA tests, digital rectal exams, and biopsies.
Prostate cancer is one of the most common killers of men its the second leading cause of cancer deaths among men in America. Its largely a disease of men over 40, so its around this age doctors recommend the first prostate screening.
Age, ethnicity, family history, nationality, genetic factors, and obesity are all risk factors for prostate cancer, and any one of these is a reason to get checked. The good news is the prognosis for prostate cancer, depending on the stage at which its diagnosed, is good compared with some other cancers. Because the condition is so common, theres a large set of data on what treatments are effective and lots of support for men with the disease
The prostate is a walnut-sized gland in men that wraps around the urethra below the bladder and produces the fluid portion of semen. Early signs of a cancerous prostate are blood in the urine and/or semen and pain or inability to urinate or ejaculate. Prostate cancer commonly metastasizes to lymph nodes in the pelvis and the bones.
The best treatment results come when prostate cancer is diagnosed early.
If the results of the PSA test and rectal exam show abnormalities, your doctor may refer you to a urologist for a biopsy, and you will make treatment decisions with your doctor based on the biopsy results.
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.

Special Types Of Psa Tests
The PSA level from a screening test is sometimes referred to as total PSA, because it includes the different forms of PSA . If you decide to get a PSA screening test and the result isnt normal, some doctors might consider using different types of PSA tests to help decide if you need a prostate biopsy, although not all doctors agree on how to use these tests. If your PSA test result isnt normal, ask your doctor to discuss your cancer risk and your need for further tests.
Percent-free PSA: PSA occurs in 2 major forms in the blood. One form is attached to blood proteins, while the other circulates free . The percent-free PSA is the ratio of how much PSA circulates free compared to the total PSA level. The percentage of free PSA is lower in men who have prostate cancer than in men who do not.
If your PSA test result is in the borderline range , the percent-free PSA might be used to help decide if you should have a prostate biopsy. A lower percent-free PSA means that your chance of having prostate cancer is higher and you should probably have a biopsy.
Many doctors recommend a prostate biopsy for men whose percent-free PSA is 10% or less, and advise that men consider a biopsy if it is between 10% and 25%. Using these cutoffs detects most cancers and helps some men avoid unnecessary biopsies. This test is widely used, but not all doctors agree that 25% is the best cutoff point to decide on a biopsy, and the cutoff may change depending on the overall PSA level.
Psa Screening Blood Test
A Prostate-specific antigen is made by the cells of the prostate gland. PSA testing is a common method to test for prostate cancer. PSA is found in semen, with a small amount in the blood. Men without prostate cancer often have PSA levels under 4 nanograms per milliliter of blood. Elevated PSA level increases the likelihood of having prostate cancer .
The American Cancer Society reports that men with a total PSA level of between 4 and 10 have roughly a 1 in 4 chance of having prostate cancer. With a total PSA of over 10, the chance of having prostate cancer rises to over 50%. Following the PSA test, if the levels are high, a doctor may suggest a repeat screening test or a prostate biopsy.
In addition to prostate cancer, there are many other factors that can affect a mans PSA levels.
