Screening Information For Prostate Cancer

How to Test for Prostate Cancer | Ask a Prostate Expert, Mark Scholz, MD

Screening for prostate cancer is done to find evidence of cancer in otherwise healthy adults. Two tests are commonly used to screen for prostate cancer:

  • Digital rectal examination . A DRE is a test in which the doctor inserts a gloved, lubricated finger into the rectum and feels the surface of the prostate through the bowel wall for any irregularities.

  • PSA blood test. There is controversy about using the PSA test to look for prostate cancer in people with no symptoms of the disease. On the one hand, the PSA test is useful for detecting early-stage prostate cancer, especially in those with many risk factors, which helps some get the treatment they need before the cancer grows and spreads. On the other hand, PSA screening may find very-slow-growing prostate cancers that would never threaten someones life. As a result, screening for prostate cancer using PSA may lead to treatments that are not needed, which can cause side effects and seriously affect a persons quality of life.

ASCO recommends that people with no symptoms of prostate cancer and who are expected to live less than 10 years do not receive PSA screening. For those expected to live longer than 10 years, ASCO recommends that they talk with their doctor to find out if the test is appropriate for them.

Other organizations have different recommendations for screening:

What Happens After The Prostate Tests

Urodynamic tests and cystoscopy may cause mild discomfort for a few hours after the procedures. Drinking an 8-ounce glass of water every half-hour for 2 hours may help reduce discomfort. The health care provider may recommend taking a warm bath or holding a warm, damp washcloth over the urethral opening to relieve discomfort. A prostate biopsy may produce pain in the area of the rectum and the perineum, which is between the rectum and the scrotum. A prostate biopsy may also produce blood in urine and semen.

An antibiotic may be prescribed for 1 or 2 days to prevent infection.

Patients with signs of infectionincluding pain, chills, or fevershould call their health care provider immediately.

How Long Will My Follow

You will have follow-up appointments for some time after your treatment. Exactly how long will depend on your cancer, any side effects of treatment and the services in your area. You will usually have appointments for several years.

After your follow-up appointments finish, you may continue to have PSA tests. Speak to your GP if you have any problems or concerns they can refer you back to the hospital. Make sure you remind them about your prostate cancer, especially if its been a while since you had treatment or a PSA test.

Psa Test: The Current Prostate Screening Standard

Before recommending when you should be screened for prostate cancer, yourdoctor will consider many factors, such as:

  • Age
  • Family history, particularly whether any of your family members have had prostate cancer
  • Race, as African-American men have a higher risk of developing prostate cancer

If your doctor determines you should undergo screening, he or she will mostlikely recommend the PSA test. For more than 30 years, the PSA test hasbeen the gold standard in prostate cancer screening. This simple blood testmeasures how much prostate-specific antigen is in your blood.

How Are Prostate Problems Diagnosed

How Do They Test For Prostate Cancer

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.

How Fast And Where Does Prostate Cancer Spread

Like other cancers, prostate cancer can spread from the site of where it first started to other sites of the body. Once it spreads, the disease may still respond to the treatment, but typically it is now no longer to be cured. Bones, liver, and lungs are the most common sites for prostate cancer metastasis. How do you know that it has spread? And how fast this metastasis?

Since the early detection of the disease is very crucial for the prognosis and outlook of patients , its very important to diagnose the disease as early as possible.

In the U.S, the number of men diagnosed with the disease at later stages decreases drastically due to the implementation of PSA screening test .

Men with many risk factors of prostate cancer should start discussing the test with their doctor earlier. Visit this section for more information about this!

The PSA test is also recommended in other countries . However whether this test is necessary for all men is debatable.

For those who eventually dont have prostate cancer in their life, the choice to take the test may put them at high risk of getting over-diagnosis, making anxiety more likely.

Therefore, some experts agree that the screening prostate cancer test is more recommended for those who have some /many risk factors of the disease. For more advice, consult more with your GP!

What Are Some Common Prostate Problems

The most common prostate problem in men younger than age 50 is inflammation, called prostatitis. Prostate enlargement, or benign prostatic hyperplasia , is another common problem. Because the prostate continues to grow as a man ages, BPH is the most common prostate problem for men older than age 50. Older men are at risk for prostate cancer as well, but it is much less common than BPH.

Other Factors That Influence Psa Levels

The PSA blood test alone cannot diagnose prostate cancer. It is possible, although rare, to have prostate cancer without raised PSA levels in the blood. A higher-than-normal PSA level doesnt automatically indicate prostate cancer either. A high PSA level is due to cancer in around one in three cases.

PSA levels can be raised by other factors, including:

  • , also known as benign prostatic enlargement .

For this reason, the PSA blood test isnt used in isolation when checking for prostate cancer.

What Are The Symptoms Of Prostate Problems

New Test to Detect Prostate Cancer Now Available

The symptoms of prostate problems may include

  • urinary retentionthe inability to empty the bladder completely
  • urinary frequencyurination eight or more times a day
  • urinary urgencythe inability to delay urination
  • urinary incontinencethe accidental loss of urine
  • nocturiafrequent urination at night
  • trouble beginning a urine stream
  • weak or interrupted urine stream
  • blockage of urine
  • urine that has an unusual color or odor
  • pain after ejaculation or during urination

Different prostate problems may have similar symptoms. For example, one man with prostatitis and another with BPH may both experience urinary urgency. Sometimes symptoms for the same prostate problem differ among individuals. For example, one man with BPH may have trouble beginning a urine stream, while another may experience nocturia. A man in the early stages of prostate cancer may have no symptoms at all. Because of this confusing array of symptoms, a thorough medical exam and testing are vital.

Discuss Prostate Cancer Testing With Your Doctor

Medical authorities do not recommend that all men should be tested for prostate cancer. In fact, most authorities suggest that men should make their own choice about whether or not to have a PSA test. If you decide to be tested, it is recommended that it should be done every two years from 50 to 69 years of age, and only if your health is such that you expect to live for at least another seven years.

Men at high risk of prostate cancer, such as men with a family history of prostate cancer , or men who have previously had an elevated test result, can start two-yearly testing from age 45. Your doctor can help you decide whether this is necessary.

While there is now some evidence that regular testing may prevent prostate cancer deaths, there are concerns that many men may be diagnosed and treated unnecessarily as a result of being screened, with a high cost to their health and quality of life .

However, the option of active surveillance, where a low-risk cancer is watched closely instead of being treated, helps to lower these risks. Active surveillance is now used quite commonly in Australia for men with low-risk prostate cancer.

If you are unsure whether or not to be tested after considering the benefits and uncertainties of testing and your own risk of prostate cancer, discuss it with your doctor.

In Australia, if you choose to be tested for prostate cancer the tests are covered by Medicare.

Reasons To Get A Colonoscopy

Colon Cancer, Colon Health, Gastroenterology

Colon cancer is more serious and more common than you might think.

In fact, 5 to 6 percent of people will develop colon cancer in their lifetimes, according to Murtaza Kittu Parekh, MD, and Rig Patel, MD, of REX Digestive Healthcare. Its the second leading cause of cancer death in the United States after lung cancer, when counting cancers that affect both men and women.

But there is good news, Dr. Parekh says. Colonoscopy makes colorectal cancer one of the few cancers we can actually prevent.

A colonoscopy is an examination of the inside lining of the colon, which is where colon cancer starts. During a colonoscopy, a long, narrow, flexible tube with an HD camera at the end is used to evaluate the rectum and colon.

Colonoscopies can detect conditions like colitis, inflammatory bowel disease and diverticulosis. But mainly, doctors are looking for precancerous or cancerous colon polyps, which are growths on the inside of the colons lining. If the doctors spot polyps, they can quickly and painlessly remove them during the same colonoscopy.

Talk to your doctor about having a colonoscopy if you are any of the following:

  • Age 45 or older
  • Older than 40 with a family history of colon cancer or colon polyps
  • Youve noticed a change in your bowel movements or have bleeding or pain, regardless of your age

Theres no reason to avoid this painless, quick and potentially lifesaving procedure.

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.

Diagnostic Accuracy Of Dre

How Do They Check For Prostate Cancer

There were 3225 participants included from 4 different studies. For each of the included studies we were able to calculate a 2×2 table for reference test results versus the diagnostic test . This data was then combined to give an overall sensitivity, specificity, PPV and NPV. This was calculated using Meta-Disc software. Overall, the pooled sensitivity and specificity for DRE as a predictor of prostate cancer in symptomatic patients was found to be 28.6% and 90.7% , respectively. These results are shown in Fig. . The pooled PPV and NPV were found to be 42.3 and 84.2%, respectively. There was no relevant data extractable regarding secondary outcomes of adverse events or cost effectiveness.

Living With Prostate Cancer

As prostate cancer usually progresses very slowly, you can live for decades without symptoms or needing treatment.

Nevertheless, it can affect your life. As well as the possible side effects of treatment, a diagnosis of prostate cancer can understandably make you feel anxious or depressed.

You may find it beneficial to talk about the condition with your family, friends, a GP and other people with prostate cancer.

Screening For Prostate Cancer

Prostate cancer is typically treatable if caught early. More than 90 percent of prostate cancers are found when the disease is in the beginning stages, confined to the prostate and nearby organs.

Unlike screenings for breast and colon cancers, there are no universal screening guidelines for prostate cancer. The U.S. Preventive Services Task Force recommends that men age 55 to 69 weigh the benefits and risks before deciding whether they should undergo screening, which is typically performed with a blood test that measures levels of a protein called prostate-specific antigen .

However, men in high-risk groupssuch as those who are of African-American descent and/or have a first-degree relative diagnosed with prostate cancer before age 65should consider speaking with their doctor about starting screenings at an earlier age.

Men older than 70 shouldnt be routinely screened for prostate cancer, according to the USPSTF.

Regardless of age or risk factors, men should get checked if they suddenly experience issues with urination, erectile dysfunction or unexplained pain.

The USPSTF suggests that, before deciding on a screening, men should seek expert advice about the benefits and harms of screening. Risks may include:

  • False positives

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:

Biopsy During Surgery To Treat Prostate Cancer

What it’s like to go for a rectal screening for 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.

Transrectal Ultrasound With Prostate Biopsy

Transrectal ultrasound is most often used to examine the prostate. In a transrectal ultrasound, the health care provider inserts a transducer slightly larger than a pen into the mans rectum next to the prostate. The ultrasound image shows the size of the prostate and any abnormal-looking areas, such as tumors. Transrectal ultrasound cannot definitively identify prostate cancer.

To determine whether a tumor is cancerous, the health care provider uses the transducer and ultrasound images to guide a needle to the tumor. The needle is then used to remove a few pieces of prostate tissue for examination with a microscope. This process, called biopsy, can reveal whether prostate cancer is present. A transrectal ultrasound with prostate biopsy is usually performed by a doctor in a health care providers office, outpatient center, or hospital with light sedation and local anesthesia. The biopsied prostate tissue is examined in a laboratory by a pathologista doctor who specializes in diagnosing diseases.

Do All Men Who Are Treated For Prostate Cancer Lose Sexual And Urinary Function

Its definitely not true that all men are incontinent and impotent after treatment for prostate cancer. Urinary incontinence is usually temporary.

There can be a sexual impact for guys who have normal function. If the cancer is near their nerve bundle, theyre going to have a decrease in sexual function. If its not, and we can do bilateral nerve sparing surgery, studies show 70 percent can get back their normal sexual function. It all depends on where the cancer is. But the truth is that we cant predict very well who will be the 30 percent who will haveor still haveED some already do have ED because of age, diabetes, hypertension or renal failure.

Why Is A Prostate

A PSA blood test is performed to detect or rule out prostate cancer. The amount of PSA in the blood is often higher in men who have prostate cancer. However, an elevated PSA level does not necessarily indicate prostate cancer. The U.S. Food and Drug Administration has approved the PSA blood test for use in conjunction with a DRE to help detect prostate cancer in men age 50 or older and for monitoring men with prostate cancer after treatment. However, much remains unknown about how to interpret a PSA blood test, its ability to discriminate between cancer and problems such as BPH and prostatitis, and the best course of action if the PSA level is high.

When done in addition to a DRE, a PSA blood test enhances detection of prostate cancer. However, the test is known to have relatively high false-positive rates. A PSA blood test also may identify a greater number of medically insignificant lumps or growths, called tumors, in the prostate. Health care providers and patients should weigh the benefits of PSA blood testing against the risks of follow-up diagnostic tests. The procedures used to diagnose prostate cancer may cause significant side effects, including bleeding and infection.

First What Is Prostate Cancer

Prostate cancer symptoms: How do they test for it in the ...

Prostate cancer is cancer that occurs in the prostate â a small walnut-shaped gland in men. This is the gland that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is one of the most common cancers in men. Thankfully some prostate cancers are slow growing, without causing serious harm. However, others are aggressive, so for both scenarios, identifying the cancer earlier is key.
