Prostate-specific antigen (PSA) is a protein produced by both malignant and normal prostate cells. The PSA test measures the levels of PSA in the blood. The results of the test are usually reported in units of ng/mL (nanograms per milliliter).
In normal males, the PSA level typically ranges from 2.5 to 4.0 ng/mL.
The main cause of an increase in PSA levels is prostate cancer.
However, there are other prostate or urinary tract health issues that can also raise PSA levels, including:
Additionally, factors such as urinary catheterization, aging, parathyroid hormone, prostate manipulation, and ejaculation can also elevate PSA levels.
On the other hand, the upper limit of the normal value, 4.0 ng/mL, may not apply to men of all age groups.
As for the normal PSA values for different age groups, the following table can be used as a reference:
| Age Range | Adjusted Normal Level (ng/mL) |
| 40-49 | 0-2.5 |
| 50-59 | 0-3.5 |
| 60-69 | 0-4.5 |
| 70 + | 0-6.5 |
The Bowtie Medical Team has compiled the following table to show the cancer risk associated with different PSA levels:
| PSA Level (ng/mL) | Risk of Cancer |
| 0-2.5 | Very low risk |
| 4-10 | 25% chance of having cancer, further test may be conducted for diagnosis |
| 10 | Very high risk, 50% chance of having cancer |
However, according to statistics from the NHS, about 3 out of 4 men with an elevated PSA level do not have cancer. Additionally, for every 7 men with a normal PSA level, one may still have prostate cancer. This indicates that the PSA test is not the best diagnostic method for prostate cancer.
The advantages of PSA testing include:
- Provides reassurance if the level is within the normal range
- Can detect early signs of prostate cancer
- Reduces the risk of death if early treatment is initiated
However, there are also disadvantages to consider:
- There is a possibility of false-positive results, leading to missed opportunities for cancer treatment
- Even without cancer, the test results can cause anxiety
- The test cannot determine the progression of cancer
Therefore, some medical articles suggest that unless there is a high familial risk, PSA testing is most suitable for men aged 55-69 years (as determined by a doctor).
If the PSA level is abnormal, it does not necessarily mean that you have prostate cancer. The doctor may recommend the following methods to determine the cause:
- Repeat the PSA test
- Perform other types of PSA tests, such as Free PSA, PHI, and 4Kscore
- Conduct additional tests, such as digital rectal examination, MRI scanning, and transrectal prostate ultrasound
- Biopsy of the prostate through transrectal needle aspiration
In Hong Kong, many private hospitals and clinics offer PSA testing services, with costs ranging from HK$2,000 to HK$8,500.

If unfortunately diagnosed with prostate cancer, both Bowtie’s Voluntary Health Insurance Scheme and Cancer Protector provide coverage for surgical and non-surgical treatments (such as chemotherapy, targeted therapy, immunotherapy, etc.).
In particular, Bowtie Pink Voluntary Medical Insurance and Cancer Protector provide full reimbursement coverage*^for all expenses related to prostate cancer treatment.
If no major health issues are found after the examination, can the examination costs be reimbursed?
As long as the insured person obtains a written reference letter from the primary care physician or registered doctor to undergo the relevant examination, the examination falls within the coverage of voluntary medical insurance.
It is recommended to inquire about the claims procedure and details from the insurance company before undergoing the examination in order to facilitate a smoother reimbursement process!
Buy insurance while you are in good health, so you don't have to worry about not being able to buy it or paying extra premiums!
How can I reduce PSA levels?
Some studies suggest that consuming more tomatoes, choosing healthy protein foods, getting sufficient vitamin D, drinking green tea, and exercising regularly can naturally lower PSA levels.
How often should men undergo PSA screening?
The Hong Kong Urological Association recommends considering PSA screening every 2 years if the PSA index is normal (<4ng/mL).
