Prostate cancer is one of the most common cancers affecting men globally, especially those over the age of 50. As awareness about men’s health grows, understanding the symptoms of prostate cancer has never been more important. Early recognition of warning signs can lead to prompt diagnosis, more effective treatment, and a better quality of life.
This article takes a detailed look at what are the symptoms of prostate cancer, explains why they occur, how to distinguish them from other prostate conditions, and what to do if you or someone you love notices these symptoms.
Understanding the Prostate and Prostate Cancer
Before diving into the symptoms, it’s helpful to know what the prostate is and how prostate cancer develops. The prostate is a small, walnut-sized gland located below the bladder and in front of the rectum. It produces seminal fluid that nourishes and transports sperm. Prostate cancer occurs when cells in the prostate gland begin to grow uncontrollably, often forming a tumour that may remain confined to the gland or spread to other parts of the body.
Why Symptoms of Prostate Cancer Often Go Unnoticed
One of the biggest challenges with prostate cancer is that, in its early stages, it often causes no noticeable symptoms. This is because the cancer usually starts in the outer part of the prostate, away from the urethra (the tube that carries urine from the bladder out of the body). As a result, symptoms may only appear once the tumour grows large enough to press on the urethra or spread beyond the prostate gland.
Key Takeaway:
Early prostate cancer often produces no symptoms. That’s why routine screening and awareness are so important, especially for men at higher risk.
Common Early Symptoms of Prostate Cancer
Early detection is critical in the fight against prostate cancer. However, in the initial stages, symptoms can be subtle, gradual, and easily mistaken for benign conditions like aging or a mild urinary infection. Understanding the common early symptoms of prostate cancer helps men take timely action and seek medical evaluation when needed.
1. Frequent Urination
One of the earliest and most noticeable symptoms of prostate cancer is an increased need to urinate. This symptom often becomes more pronounced at night, a condition known as nocturia. Men may find themselves waking up multiple times to visit the bathroom, which can disturb restful sleep and cause persistent daytime fatigue. The underlying reason is that the enlarging prostate may put pressure on the urethra, triggering the bladder to empty more frequently.
2. Difficulty Starting or Stopping Urine Flow
As prostate cancer develops, it can partially block the passage of urine through the urethra. This makes it harder for men to initiate the stream of urine, leading to a delay or straining at the start. Similarly, stopping the flow can also be challenging, sometimes causing dribbling at the end of urination. This hesitant or interrupted pattern is a classic urinary symptom that should not be ignored.
3. Weak or Interrupted Urine Stream
Many men with early prostate cancer report a urine stream that is weaker than usual or one that stops and starts unexpectedly. This weak or interrupted flow is often a result of the tumour narrowing or obstructing the urethra. Over time, this can give the sensation that the bladder never fully empties, leading to discomfort and frequent returns to the bathroom.
4. Pain or Burning During Urination
Although less common, some men experience a burning or painful sensation while urinating. This symptom, called dysuria, may mimic the symptoms of a urinary tract infection. However, if the pain is persistent or not relieved by standard treatments, it could be an early warning sign of prostate cancer or another underlying issue and should be checked by a healthcare provider.
5. Blood in Urine (Hematuria)
Noticing blood in the urine is a concerning sign that always warrants immediate medical evaluation. Known as hematuria, this symptom can appear as pink, red, or brownish discoloration in the urine. While hematuria is not always caused by prostate cancer it can also result from infections, kidney stones, or trauma—it remains a significant warning sign.
6. Blood in Semen
Sometimes, men may also notice blood in their semen. This can be alarming and may indicate an underlying prostate or urological problem. While not specific to prostate cancer, it is an important symptom to mention to your doctor, especially when accompanied by other urinary changes.
Advanced Symptoms of Prostate Cancer
As prostate cancer moves beyond its early, often silent stages, it can produce more noticeable and sometimes alarming symptoms. These advanced symptoms typically arise when the cancer grows locally to affect nearby tissues or spreads (metastasises) to distant organs, such as the bones or lymph nodes. Recognising these advanced symptoms of prostate cancer is crucial for timely medical intervention and better outcomes.
1. Pain in the Hips, Back, or Pelvis
One of the hallmark signs that prostate cancer has spread is persistent pain, especially in the hips, back, ribs, or pelvis. This bone pain may begin as a dull ache but can become intense and unrelenting over time. The pain can limit mobility, disrupt sleep, and reduce quality of life. Bone pain in advanced prostate cancer is usually due to the cancer cells invading the bone tissue, which can weaken bones and increase the risk of fractures.
2. Unexplained Weight Loss
Sudden and unintended weight loss is a red flag for many advanced cancers, including prostate cancer. As cancer grows and spreads, it can disrupt normal metabolism, suppress appetite, and cause muscle wasting (cachexia). This weight loss often occurs even when there is no intentional change in diet or exercise and may be accompanied by a general feeling of being unwell. If you notice significant weight loss without a clear reason, it’s important to seek medical advice promptly.
3. Fatigue and Weakness
Chronic fatigue is a common advanced symptom of prostate cancer, often linked to the body’s response to the growing tumour, spreading cancer cells, or cancer treatments. Fatigue may be overwhelming and not relieved by rest. It can interfere with daily activities, work, and social life. As cancer advances, the body diverts energy towards fighting the disease, which can leave individuals feeling persistently tired and weak.
4. Swelling in the Legs or Feet
Swelling (oedema) in the legs, ankles, or feet can develop if prostate cancer spreads to lymph nodes in the pelvis or abdomen, or if the tumour obstructs normal lymphatic drainage. This swelling can be uncomfortable and make walking or standing difficult. Sometimes, the swelling can also be a sign that blood flow is being blocked by cancer pressing against blood vessels.
5. Loss of Bladder or Bowel Control
Advanced prostate cancer can press on the bladder, rectum, or the nerves controlling these organs. This pressure or nerve involvement can lead to urinary incontinence (leakage or inability to control urination) or bowel incontinence (loss of bowel control). These symptoms can be distressing and may require specialised management to maintain dignity and comfort.
6. Erectile Dysfunction
Difficulty achieving or maintaining an erection, known as erectile dysfunction, is another possible advanced symptom of prostate cancer. It can result from cancer itself damaging nerves or blood vessels in the pelvic area, or as a side effect of treatments such as surgery, radiation, or hormone therapy. Erectile dysfunction can significantly affect quality of life, relationships, and self-esteem.
Common Symptoms of Prostate Cancer
| Symptom | Early Stage | Advanced Stage |
|---|---|---|
| Frequent urination | Yes | Yes |
| Difficulty starting/stopping urination | Yes | Yes |
| Weak/interrupted urine stream | Yes | Yes |
| Blood in urine/semen | Sometimes | Sometimes |
| Pain or burning during urination | Sometimes | Sometimes |
| Bone pain (hips, back, pelvis) | No | Yes |
| Unexplained weight loss | No | Yes |
| Fatigue, weakness | Sometimes | Yes |
| Swelling in legs/feet | No | Yes |

Why Do Prostate Cancer Symptoms Occur?
Understanding why symptoms appear helps you recognise their significance:
- Urinary symptoms result from the prostate gland pressing against or partially blocking the urethra as it enlarges.
- Blood in urine/semen can occur if the cancer invades nearby blood vessels.
- Bone pain and swelling are signs that the cancer has spread (metastasized) beyond the prostate.
- Unexplained weight loss, fatigue, and general malaise result from cancer’s impact on the body’s metabolism and organ function.
How Are Prostate Cancer Symptoms Different from Other Prostate Conditions?
It’s important to note that many symptoms of prostate cancer are similar to those of benign conditions, such as benign prostatic hyperplasia (BPH) and prostatitis (inflammation of the prostate). Here’s how they compare:
- BPH commonly causes frequent urination, weak stream, and incomplete emptying but is not cancerous.
- Prostatitis can cause pain, burning urination, and fever, often with a sudden onset.
Key Point:
Symptoms alone cannot confirm prostate cancer. Medical evaluation and testing are essential for an accurate diagnosis.
When Should You See a Doctor?
If you notice any of the following symptoms, especially if they are new, persistent, or worsening, consult a healthcare professional right away:
- Blood in urine or semen
- Persistent pain in the back, hips, or pelvis
- Difficulty urinating, weak stream, or frequent urination
- Unexplained weight loss or fatigue
- Swelling in the legs or feet
Prompt evaluation can help rule out other causes and ensure early intervention if cancer is present.
Who Is at Higher Risk of Prostate Cancer?
Understanding your risk can help you interpret symptoms and decide when to seek screening or medical advice.
Key Risk Factors
- Age: Risk increases significantly after age 50.
- Family History: Men with a father or brother who had prostate cancer are at higher risk.
- Race: African-American men are at higher risk and may develop more aggressive cancers.
- Diet: Diets high in red meat and dairy and low in fruits/vegetables may increase risk.
- Obesity: May increase the risk of more aggressive cancer.
Men with these risk factors should be especially vigilant about symptoms and regular screening.
How Is Prostate Cancer Diagnosed After Noticing Symptoms?
When symptoms raise suspicion for prostate cancer, your doctor may order several tests:
1. Digital Rectal Exam (DRE)
A physical examination where the doctor feels the prostate through the rectal wall to check for enlargement, lumps, or hard areas.
2. Prostate-Specific Antigen (PSA) Blood Test
A higher-than-normal PSA level can indicate prostate cancer, but also other prostate issues.
3. Imaging Tests
- Transrectal ultrasound (TRUS): Uses sound waves to image the prostate.
- MRI or CT scans: Help identify suspicious areas or assess cancer spread.
4. Prostate Biopsy
The only definitive way to diagnose prostate cancer. Small samples of prostate tissue are removed and examined under a microscope.
How Fast Do Symptoms of Prostate Cancer Progress?
Prostate cancer often develops slowly and can take years to cause noticeable symptoms. Some aggressive forms, however, progress more rapidly and cause symptoms sooner. That’s why screening and regular check-ups are critical, even in the absence of symptoms.
Can Prostate Cancer Cause No Symptoms?
Yes, many men have no symptoms at all in the early stages. That’s why some cases are only detected through routine screening or evaluation for unrelated issues. Silent or “asymptomatic” prostate cancer is not uncommon.
Early Detection Saves Lives
The earlier prostate cancer is caught, the higher the chance of successful treatment and long-term survival. For men at average risk, routine PSA screening and DRE are typically recommended starting between ages 50 and 55, or earlier if risk factors are present.
Living With Prostate Cancer Symptoms
Coping with prostate cancer symptoms can be physically and emotionally challenging. Early recognition, prompt medical care, and support from loved ones are vital. There are many treatment options available, from monitoring low-risk cancers to surgery, radiation, hormone therapy, and newer targeted treatments.
Lifestyle tips:
- Stay hydrated
- Eat a balanced, plant-rich diet
- Get regular exercise
- Maintain a healthy weight
- Avoid smoking and limit alcohol
- Keep up with regular doctor visits
