The PSA testpsa test

The introduction of Prostate Specific Antigen (PSA) testing in 1987 has led to a rapid rise in the reported incidence of prostate cancer in the United States (1).

PSA is a glycoprotein that is produced exclusively in the prostate. Men suffering from prostate conditions typically have an increased production of PSA, which causes an increase in blood PSA levels.

A simple blood test can be carried out to measure PSA levels. There is some controversy surrounding the use of the PSA test as a screening for prostate cancer.

 

When should you consider having a PSA test?

Since the risk of prostate cancer increases with age, it is recommended that men over the age of 50 should consider having a PSA test.

African American men and men with a family history of prostate cancer have a heightened risk of prostate cancer. Therefore, these men should consider having a PSA test at the age of 45.

Benefits of PSA test psa test

  • It is a test with very few immediate side effects.
  • Having a PSA test can lead to earlier detection of prostate cancer.

  • However, there are some limitations of the PSA test. There are many things you should consider before having a PSA test.
  • A PSA test is unable to distinguish between different causes of a rise in PSA. Prostate cancer, benign prostatic hyperplasia (BPH) and prostatitis can all cause a rise in PSA. Also, PSA levels increase with age as the prostate increases with age.
  • A PSA test is also unable to distinguish which men diagnosed with prostate cancer who will benefit from treatment and who would not. Therefore, further tests will be required.
  • Those with an elevated PSA are likely to undergo a biopsy. Nearly 70% of men that are offered a biopsy will have no sign of prostate cancer.
  • Therefore, the PSA test can lead to having an unnecessary invasive procedure that can cause a serious infection.

 

Alternative to biopsy  psa testpsa test

Magnetic Resonance Imaging (MRI) is a non-invasive alternative to biopsies. An MRI test provides information on prostate volume and the stage and size of lesions within the prostate. The use of MRI can reduce the number of men undergoing unnecessary biopsies by 25% (3).

Prostate cancer diagnosis

90% of those diagnosed with prostate cancer will choose to have some form of treatment. This includes surgery, radiation therapy, or androgen deprivation. All of these treatments may be associated with adverse effects, such as urinary, bowel and erectile dysfunction.

 

Alternative to prostate cancer treatments psa test

Treatment for prostate cancer may reduce the risk of advancing and spreading to other organs.

However, prostate cancer is a very slow growing compared to other cancers. The majority of men with prostate cancer do not die from prostate cancer.

This is shown in a study published in the New England Journal of Medicine (4). The study demonstrated that after 10 years, there were no differences in death rates in those that underwent prostate cancer treatments compared to those who elected to undergo active surveillance (4).

Unless you are suffering from an aggressive form of prostate cancer, active surveillance is the best option due to improved quality of life. You will not have to suffer from long-term side effects of prostate cancer treatment. 

 

Conclusion

A review study recently published in the British Medical Journal found that PSA testing only slightly reduces the risk of dying from prostate cancer, but does not reduce the risk of death from all causes (2).

Therefore, taking a PSA test is not vital to your long-term health. If you decide to have a PSA test it is important to remember:

Avoid having a biopsy after a PSA test because this can cause a serious infection.

If you are diagnosed with prostate cancer you should remember it is typically a slow growing cancer. Choose active surveillance if you do not have an aggressive form of prostate cancer.

Active surveillance will prevent you from suffering the side effects of aggressive prostate cancer treatments.

    I fully agree that the PSA test is highly overrated. Mine was 6.5 at age 78 when I had the HoLEP operation for BPH. There was zero cancer found and the operation completely cured the BPH with no side effects.
    One of the statements regarding pomegranate contained the usual absurdity regarding measures to reduce the PSA number, as if having a higher than normal PSA was a disease in itself. Reducing the PSA wouldn’t reduce any cancer growth if present.
    I also agree that the PSA can be a very misleading factor when considering the liklihood of prostate cancer. The inventor of the PSA test, Dr Ablin wrote a book
    called The Great Prostate Hoax, describing how certain companies adopted the PSA test to comport to their agenda of making money on the test.

    I appreciate your information on good prostate health and current news on the subject. I am 89, and very interested in you articles on prostate health. I will always keep in touch with you to benefit my prostate health info.

    I’m a 74 and had a steady psa score going higher from 4 to 5 to 7 to 9 and this year 14. My urologist wants to do the biopsy to see what’s going on. You’re advice please.

    • Ben Ong

      Hi John,

      I think the best thing to at this point would be to give us a call on 1-888-868-3554. That way we can get to know a little bit more about your situation and give you the correct advice (which you can then discuss with your doctor).

      I wish you good health,
      Ben

    Hi Ben,
    Your help and information is brilliant. Last December, I had a PSA check after difficulty in passing urine. It was 6.7. I was referred to a urologist 2 weeks later when things had improved and the reading was 5.0. I am 71 years old, and see from your info, it could be 6.5 at my age anyway. It has made my worry a little less. At 55 yrs old it was tested at 3.0.

    what is considered a low psa result where as you would not have to worry

    • Ben Ong

      The following are some general PSA level guidelines: 0 to 2.5 ng/mL is considered safe. 2.6 to 4 ng/mL is safe in most men but talk with your doctor about other risk factors. 4.0 to 10.0 ng/mL is suspicious.

      Hope this helps!

      Ben

    I totally agree with this sound advice – even though I had a PSA score of 9.5 at age 75, I refused a recommended biopsy. I have elected to monitor my symptoms with an improved diet and taking more exercise. So far, my PSA has reduced by one. I hope that this downward trend will continue.

  7. Frank Baker

    Two years ago l was diagnosed with low grade prostate cancer with a gleason score of 3+3=6. I just had a resent biopsy and the cancer stayed the same 3+3=6 no change. It pays to go with active surveillance for low grade prostate cancer.

  8. Robin weldon

    Very helpful advice and also very reassuring.
