How Are Prostate Problems Diagnosed

Avoid prostate biopsies with new cancer screening

To diagnose prostate problems, the health care provider will perform a digital rectal exam . The health care provider will also ask the patient

  • when the problem began and how often it occurs
  • what symptoms are present
  • whether he has a history of recurrent urinary tract infections
  • what medications he takes, both prescription and those bought over the counter
  • the amount of fluid he typically drinks each day
  • whether he consumes caffeine and alcohol
  • about his general medical history, including any major illnesses or surgeries

Answers to these questions will help the health care provider identify the problem or determine what medical tests are needed. Diagnosing BPH may require a series of medical exams and tests.

Testing The Liquid Biopsy Test

Figuring out how liquid biopsies might fit into the diagnostic process is something that researchers on the DETECT study hoped to find out.

According to the studys results, 96 of the 10,000 enrolled women received diagnoses of cancer during the trial. Of those, 26 were identified by the blood test, 24 by standard screening methodsand 46 after they developed symptoms.

Of the patients diagnosed by the blood test, 14 had hard-to-find cancers in organs such as ovaries, kidneys or the lymphatic system. Nine of these tumors had not yet spread beyond their original sites.

One of the things we wanted to see with this trial was if we were competing with the standard of care, or if the test is additive and synergistic, Papadopoulos says. We detected 26 cancers with our blood tests within the population that we tested. And then detected with the standard of care. So the blood test doubled the screen-detected cancers, which was a very good result.

According to Buchanan, the goal of the trial was primarily to assess the tests feasibility and safety. Researchers wanted to know how well it worked, but also if it could be used to minimize negative outcomes like false positives that would lead people to have additional medical tests.

Thats why the GRAIL test can tell the clinician not only if the patient likely has a tumor but also what type of cancer it is likely to be. In a clinical trial of the test, researchers detected more than 50 cancer types with 93% accuracy.

What Abnormal Results Mean

A high PSA level has been linked to an increased chance of having prostate cancer.

PSA testing is an important tool for detecting prostate cancer, but it is not foolproof. Other conditions can cause a rise in PSA, including:

  • A larger prostate
  • Recent tests on your bladder or prostate
  • Catheter tube recently placed into your bladder to drain urine

Your provider will consider the following things when deciding on the next step:

  • If you had a PSA test in the past and how much and how fast your PSA level has changed
  • If a prostate lump was found during your exam
  • Other symptoms you may have
  • Other risk factors for prostate cancer, such as ethnicity and family history

Men at high risk may need to have more tests. These may include:

  • Repeating your PSA test, most often sometime within 3 months. You may receive treatment for a prostate infection first.
  • A prostate biopsy will be done if the first PSA level is high, or if the level keeps rising when the PSA is measured again.
  • A follow-up test called a free PSA . This measures the percentage of PSA in your blood that is not bound to other proteins. The lower the level of this test, the more likely it is that prostate cancer is present.

Other tests may also be done. The exact role of these tests in deciding on treatment is unclear.

  • A urine test called PCA-3.
  • An MRI of the prostate may help identify cancer in an area of the prostate that is hard to reach during a biopsy.

Blood Testing And Cancer

In addition to serving as a general health barometer, blood work plays an important role in diagnosing certain types of cancer. For instance, leukemia, a cancer that affects the bodys blood-forming tissues, can sometimes be detected in a routine blood test. Specifically, the CBC test measures the levels of the various types of blood cells circulating in the bloodstream, including red blood cells, white blood cells and platelets. Although an abnormal result could point to leukemia, it is important to note that it could also indicate a benign inflammatory condition. Therefore, a physician will typically order follow-up testing to confirm or rule out a leukemia diagnosis.

Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present. One common example is theprostate-specific antigen test, which measures the level of PSA in the blood. An elevated level of PSAa protein produced by the prostate glandmay be a sign of prostate cancer.

Although blood work cannot currently be used on its own to conclusively diagnose cancer, it is often used in conjunction with other diagnostic tests, such as:

  • A physical examination
  • Imaging tests, such as X-rays, CT scans, MRIs, ultrasounds, bone scans and PET scans

What This Means For You

Blood test superior to PSA for detecting high

The Prostate Cancer UK spokesperson sounds a note of caution for now, pointing out that until these studies have been conducted, we dont have enough information about its benefits.

This innovative testing method is an interesting new approach, but there simply hasnt been enough detailed research into its effectiveness for us to be able to recommend for its use at this stage, he says. Until then, we would not recommend that anyone use this test as a substitute for current standard methods.

Of course, research in the field will be continuing apace.

In order to save more lives from prostate cancer it is crucial that we create a diagnostic process that is robust enough to routinely diagnose men early and accurately, says the spokesperson.

It can help ease pressure and swelling by releasing fluids that build up in the prostate. Small studies have found that massaging the area several times a week — along with taking antibiotics — can give relief from pain and pressure. Sometimes a doctor might do a prostate massage during a prostate exam.

How Is The Psa Test Used In Men Who Have Been Treated For Prostate Cancer

The PSA test is used to monitor men after surgery or radiation therapy for 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 the recurrence causes symptoms.

However, a single elevated PSA measurement in someone who has a history of prostate cancer does not always mean that the cancer has come back. Someone who has been treated for prostate cancer should discuss an elevated PSA level with their 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.

A rising trend in PSA level over time in combination with other findings, such as an abnormal result on imaging tests, may lead the doctor to recommend further cancer treatment.

Medicare Coverage For A Psa Blood Test

Medicare Part B covers PSA tests once every 12 months, beginning on the Medicare beneficiarys 50th birthday. If youre on Medicare before 50, and your physician feels its medically necessary, Medicare will cover the test. PSA tests fall under preventive screenings, so there should be no charge. The same rules will apply to Medicare Supplement insurance and Medicare Advantage plans.

If you’re a man over age 55, you may have already had a PSA, or prostate-specific antigen test. This test screens for prostate cancer by measuring the amount of a protein in your bloodstream released by cells in your prostate gland.

This test isn’t just for screening, though. You’ll also have it after a prostatectomy — surgery to take out all or part of your prostate. This will tell you how well the treatment worked and whether your cancer has come back.

You’ll need this test every few months after your operation. But getting tested for cancer many times can cause a lot of anxiety. And because the results aren’t always clear, you may worry about them.

A little knowledge can help calm your fears. Before you have this test, find out what to expect. Ask your doctor what your results might mean and what will happen if your PSA level is higher than it should be.

How To Get A Psa Test

Consult with your general practitioner or urologist about receiving a PSA test in their offices. PSA tests are typically covered without co-pay or deductible by Medicare once a year for men 50 years and older. Many states now have laws which require private health insurers to cover the costs for PSA testing. However, additional PSA test costs may need to be covered by the patient. For those without insurance, or for those with insurance that does not cover PSA testing, free tools are available through advocacy groups, such as ZERO.

Companies such asimawaretm also offer in-home PSA testing kits and telemedicine appointments to discuss your PSA test results with a licensed physician. All imaware test kits are easy to use. After registering the test kit online, results will populate in the secure patient portal within 5-7 business days. You can submit your receipt of this test to insurance for potential reimbursement.

At-Home testing is now at a point where results can be provided accurately and quickly within 5 business days, with real physicians providing telemedicine support through the entire testing process

What Is Cancer Screening

Cancer is a disease when the cells of the body grow out of control. Cancer screening is having tests to look for signs of cancer before you have any symptoms. By the time cancer causes symptoms, it may have already spread to other parts of your body. A screening test may help find cancer early, when it may be easier to treat.

Cancer screening only tells you whether you might have cancer. It doesn’t diagnose cancer. If a screening test shows signs of cancer, you’ll need to have other tests to find out if you do have cancer and how serious it may be.

When To Get Tested

You’ll have your first follow-up PSA test 1 to 3 months after your surgery. You need to wait because some PSA stays in your blood after your prostate is removed. If you wait until it has cleared, that will make an accurate result more likely.

Then you’ll have repeat PSA tests once every 6 to 12 months for about 5 years. If your doctor says chances are high that your cancer will come back, you may need them once every 3 months. If your PSA levels stay normal, you can switch to once-a-year PSA tests. Ask your doctor how often you’ll need a test.

Multicancer Early Detection Tests

Multicancer early detection tests are tests that measure biological signals in body fluids that may be shed by cancer cells. These signals are also known as biomarkers or tumor markers. Depending on which signals the MCED test measures, it may detect several different types of cancer. Whether MCED tests are effective for cancer screening in people without symptoms is unknown and needs to be assessed through randomized clinical trials.

No MCED tests have been approved by the US Food and Drug Administration. However, a health care provider may be able to order an MCED test for a patient.

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 screening 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.

If you are thinking about being screened, learn about the possible benefits and harms of screening, diagnosis, and treatment, and talk to your doctor about your personal risk factors.

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 If My Psa Is High

First of all, dont panic. There are many possible reasons for a high PSA level, most of which are not cancer. Even if you do have prostate cancer, the prognosis varies and some types of prostate cancer are so slow growing that they do not need treatment.

If you have increased PSA levels your doctor will need to order additional blood tests to determine what is raising your PSA levels. These tests may include:

You may also need imaging tests, such as magnetic resonance imaging , to assess your prostate. A digital rectal exam is also recommended to detect an enlarged prostate or lumps that may be a sign of cancer. If something is found, a prostate biopsy may be recommended.

Further Tests For Prostate Cancer

Prostate cancer and PSA test results: what happens next?

If results of the PSA test or the DRE are abnormal, a urologist will likely recommend a biopsy, where small samples of tissue are removed from the prostate and examined.

If cancer is diagnosed, other tests may be used to check the progression of the cancer, including:

  • magnetic resonance imaging scan of the prostate often done before a biopsy
  • bone scan to check whether or not cancer cells have spread to the bones
  • computed tomography scan a specialised x-ray
  • pelvic lymph node dissection a nearby lymph node is removed and examined to check whether or not cancer cells have entered the lymphatic system .

Information Gained From Blood Tests For Cancer

Blood testing is one of the many tools that doctors use to diagnose and manage cancer. Blood tests provide information about:

  • Overall health status
  • Abnormal levels of chemicals and proteins in your blood that may indicate cancer
  • High or low blood cell count
  • Treatment options depending on the type and severity of cancer
  • If cancer has come back
  • Whether treatment is working or the disease is further developing

Although blood tests are useful in cancer diagnosis, other tests are necessary to confirm a diagnosis. Other tests to diagnose cancer include biopsies, x-rays, CT scans, MRIs, physical exams, mammograms, and pap smears.

Getting The Results Of The Biopsy

Your biopsy samples will be sent to a lab, where they will be looked at with a microscope to see if they contain cancer cells. Getting the results usually takes at least 1 to 3 days, but it can sometimes take longer. The results might be reported as:

  • Positive for cancer: Cancer cells were seen in the biopsy samples.
  • Negative for cancer: No cancer cells were seen in the biopsy samples.
  • Suspicious: Something abnormal was seen, but it might not be cancer.

If the biopsy is negative

If the prostate biopsy results are negative , and the chance that you have prostate cancer isnt very high based on your PSA level and other tests, you might not need any more tests, other than repeat PSA tests sometime later.

But even if many samples are taken, biopsies can still sometimes miss a cancer if none of the biopsy needles pass through it. This is known as a false-negative result. If your doctor still strongly suspects you have prostate cancer , your doctor might suggest:

  • Getting other lab tests to help get a better idea of whether or not you might have prostate cancer. Examples of such tests include the Prostate Health Index , 4Kscore test, PCA3 tests , and ConfirmMDx. These tests are discussed in Whats New in Prostate Cancer Research?
  • Getting a repeat prostate biopsy. This might include getting additional samples of parts of the prostate not biopsied the first time, or using imaging tests such as MRI to look more closely for abnormal areas to target.

What Is The First Test For Detecting Prostate Problems

The first test for detecting prostate problems is a blood test to measure prostate-specific antigen , a protein made only by the prostate gland. This test is often included in routine physical exams for men older than age 50. Because African American men have higher rates of getting, and dying from, prostate cancer than men of other racial or ethnic groups in the United States, medical organizations recommend a PSA blood test be given starting at age 40 for African American men. Medical organizations also recommend a PSA blood test be given starting at age 40 for men with a family history of prostate cancer. Some medical organizations even recommend a PSA blood test be given to all men starting at age 40.

If urination problems are present or if a PSA blood test indicates a problem, additional tests may be ordered. These tests may require a patient to change his diet or fluid intake or to stop taking medications. If the tests involve inserting instruments into the urethra or rectum, antibiotics may be given before and after the test to prevent infection.
