When you notice a change in your waterworks or feel a new discomfort in the pelvis, it is natural for your mind to jump to the worst-case scenario. For men, the word “prostate” is almost inextricably linked with “cancer.”
However, the prostate is a complex gland prone to several conditions, many of which are benign. The two most common reasons for concern are Prostatitis (inflammation/infection) and Prostate Cancer, often sharing a confusingly similar set of symptoms.
This overlap can cause significant anxiety. You might experience urgency, pain, or even an elevated PSA result and assume it is cancer, when it may be a treatable infection. Conversely, you might dismiss a subtle change as “just an infection” when it actually requires investigation.
At 108 Harley Street, we believe accurate diagnosis starts with understanding the nuance. Here is how we distinguish between the two.
The Confusion: Why Do Different Conditions Feel the Same?
To understand the symptoms, you must first understand the anatomy. The prostate is a walnut-sized gland that sits directly below the bladder, wrapping around the urethra (the tube you urinate through).
Because of this location, any issue that causes the prostate to swell, whether it is a tumour, a bacterial infection, or benign enlargement (BPH), will put pressure on the urethra and irritate the bladder.
The result? The “mechanical” symptoms are often identical. Both conditions can cause you to wake up at night to urinate, struggle to start your stream, or feel like your bladder is never quite empty. The difference lies in the type of onset and the presence of pain.
Symptom Checker: What Are You Feeling?
While only a medical professional can provide a definitive diagnosis, looking at the pattern of symptoms can offer clues.
Urinary Symptoms (The Common Ground)
If your primary issue is obstructive, weak flow, dribbling, hesitating before you start, this indicates the prostate is pressing on the tube.
- Prostatitis: This often comes on suddenly. You were fine last week; now you are struggling to pee.
- Prostate Cancer: Early cancer rarely causes obstruction. If it does, it usually develops slowly over months or years.
Pain & Discomfort (The Key Differentiator)
This is often the most telling sign.
- Prostate Cancer: In its early, treatable stages, prostate cancer is usually painless. It is a “silent” disease.
- Prostatitis: This is almost always painful. Men often describe a dull ache in the perineum (the area between the scrotum and anus), pain at the tip of the penis, lower back pain, or discomfort during ejaculation. If you are in pain, it is statistically more likely to be inflammation or infection than early-stage cancer.
The “Red Flags” (Blood)
Finding blood in your urine (haematuria) or semen (haematospermia) is frightening.
- It can be both: Blood can be a sign of advanced cancer, but it is also a very common symptom of a severe prostate infection or even a burst blood vessel. It is a “red flag” that demands immediate imaging, but it is not a confirmation of malignancy.
The “PSA Trap”: Can Infection Raise Your Numbers?
The Prostate-Specific Antigen (PSA) blood test is our primary screening tool for cancer, but it is not perfect. PSA is a protein produced by prostate cells. When prostate cells are damaged or irritated, they leak more PSA into the bloodstream.
Prostatitis can cause massive PSA spikes. A severe infection can drive a PSA score up to 20, 30, or even higher, numbers often associated with advanced cancer, in a matter of days. Once the infection is treated with antibiotics, the PSA usually returns to normal.
This is why a high PSA result alone is not a cancer diagnosis. It is simply an indication that the prostate is unhappy. Our job is to find out why.
How We Tell the Difference (The Diagnostic Pathway)
When you come to 108 Harley Street with overlapping symptoms, we follow a precise diagnostic pathway to rule out cancer without jumping to unnecessary conclusions.
1. The Physical Check (DRE)
A Digital Rectal Examination gives us immediate tactile information.
- Prostatitis: The gland often feels “boggy,” swollen, warm, and is exquisitely tender to the touch.
- Cancer: The gland may feel hard, nodular, or asymmetrical, but is usually not painful when touched.
2. Urine Culture & Semen Analysis
Before we scan or biopsy, we check for bacteria. If we find an infection, we treat it. Many patients find their symptoms vanish and their PSA drops significantly after a simple course of antibiotics.
3. The mpMRI Scan
If symptoms persist or the PSA remains elevated, we use Multiparametric MRI (mpMRI). This is a game-changer in diagnostics. It allows us to see the difference between inflamed tissue (which looks diffuse and hazy) and a tumour (which looks like a distinct, dense target).
Treatments Are Worlds Apart
Distinguishing between these conditions is critical because the treatments are polar opposites.
- Prostatitis is treated with long courses of antibiotics, anti-inflammatories, and lifestyle changes (avoiding caffeine/spicy food).
- Prostate Cancer management ranges from Active Surveillance (monitoring) to surgery or focal therapy.
Mistaking one for the other can lead to unnecessary biopsies for infection, or delayed treatment for cancer.
Conclusion: Don’t Guess, Get Tested
The “symptom overlap” is real, and it is confusing. While reading about symptoms can help you understand what might be happening, it cannot replace a clinical assessment. The presence of pain usually points away from cancer, but the absence of pain does not guarantee you are clear.
If you are experiencing urinary changes, pelvic pain, or have noticed blood in your urine, do not wait for it to resolve on its own.
If you are concerned about your symptoms, please contact our Prostate Clinic to book a consultation with one of our urology consultants. Alternatively, seek immediate advice from your GP or a medical professional. Early detection is the most effective tool we have.
