An increase of approximately 1 in PSA levels over two consecutive years raises concern for the possibility of prostate cancer, but it is not definitive. Further evaluation, including additional testing and possibly a biopsy, may be necessary to determine the underlying cause of the elevated PSA levels?

Dear Dr.
Du,
I am 51 years old.
During my health check-ups, my PSA levels were consistently around 1.4 until 2014.
However, last year, the level increased to 2.6, and this year it has risen to 3.56.
I won't be able to schedule an appointment until mid-November, and I am quite worried.
Could you please inform me if an increase of 1 in PSA levels over two consecutive years significantly raises the likelihood of prostate cancer? Thank you.

Hello: The prostate index is a reference and should not be solely relied upon for diagnosis.
Additionally, clinically, the index may fluctuate slightly depending on certain conditions of the prostate.
You mentioned that these are numbers from a health check; if possible, I recommend finding a convenient hospital for regular check-ups to establish a reference point, as there can be some variations in data between different laboratories.
Furthermore, it is advisable to ensure adequate sleep, engage in moderate exercise (such as walking), pay attention to any difficulties in urination, and avoid overly stimulating foods and beverages.
This may help lower the index.
However, if it continues to rise, it is important to be vigilant and seek advice from a clinical physician for a definitive diagnosis.
Thank you.

A rising PSA (Prostate-Specific Antigen) level can indeed be a concerning indicator when it comes to prostate health, but it is important to understand that it is not a definitive marker for prostate cancer. PSA is a protein produced by both normal and malignant cells of the prostate gland, and its levels can be influenced by a variety of factors, including age, prostate size, and the presence of benign conditions such as benign prostatic hyperplasia (BPH) or prostatitis (inflammation of the prostate).

In your case, the increase in PSA levels from 1.4 to 2.6 and then to 3.56 over the past few years does warrant attention, especially since you have experienced a significant rise. Generally, a PSA level below 4.0 ng/mL is considered normal, but this threshold can vary based on individual risk factors and age. The rate of increase in PSA levels, known as PSA velocity, can also provide additional context. A rapid increase in PSA levels over a short period may raise suspicion for prostate cancer, while a gradual increase may be more indicative of benign conditions.

It is also essential to consider the context of your overall health and any symptoms you may be experiencing. For instance, if you have urinary symptoms or other related issues, these could also influence PSA levels. Furthermore, factors such as recent ejaculation, prostate manipulation (like a digital rectal exam), or infections can temporarily elevate PSA levels.

Given your situation, it is advisable to consult with a urologist who can provide a thorough evaluation. They may recommend further testing, such as a repeat PSA test, free PSA test, or even a prostate biopsy if they deem it necessary. The free PSA test can help differentiate between benign and malignant causes of elevated PSA levels; typically, a lower percentage of free PSA indicates a higher risk of prostate cancer.

In summary, while a rising PSA level can be a warning sign, it is not a definitive indicator of prostate cancer. The interpretation of PSA levels should always be done in conjunction with clinical findings, patient history, and additional diagnostic tests. It is crucial to maintain open communication with your healthcare provider to monitor your prostate health and determine the best course of action based on your individual risk factors and overall health status. Regular check-ups and discussions about any changes in your health are key to proactive management of prostate health.
