What are the first signs of complications associated with untreated, progressive prostate cancer?

Before discovering the signs of complications, check out the symptoms to look out for in our guide : What are the symptoms of prostate cancer?

If prostate cancer is not detected or treated in time, it can progress and lead to serious complications. These complications can occur at an advanced stage of the disease, affecting not only the prostate but also other parts of the body. Recognising these early signs is crucial to acting quickly. Here’s everything you need to know.

Why do complications arise?

As prostate cancer progresses, it can invade neighbouring tissues or spread to other organs, leading to what are known as metastases. These complications are often caused by uncontrolled tumour growth or delayed treatment.

Signs of prostate cancer complications

Urinary complications

Acute urinary retention: A sudden inability to urinate, often accompanied by intense pain.
Blood in the urine (haematuria) : A sign that the tumour is affecting the urinary tract.
Common urinary tract infections: Resulting from partial or total blockage of the urethra.
Kidney failure: If the tumour blocks the flow of urine over a long period.

Bone pain

When cancer spreads to the bones (bone metastases), it can cause :

Intense pain in the back, hips or ribs.
Increased fragility of bones, leading to fractures.

Neurological disorders

Weakness or numbness in the legs: Possible indication of spinal cord compression.
Difficulty walking : Linked to pain or nerve complications.

Hormonal and sexual disorders

Severe erectile dysfunction: Caused by nerve or vascular damage due to the tumour.
Hot flushes or intense fatigue: Often linked to advanced hormone treatments.

Fatigue and unexplained weight loss

These signs may indicate that the cancer has spread or that the body as a whole has been affected.

Quand consulter en urgence ?

Some symptoms require immediate consultation :

Persistent or severe bone pain.
Sudden inability to urinate.
Weakness or paralysis of the lower limbs.
Blood in urine or semen.
Rapid weight loss associated with extreme fatigue.

Don’t ignore these signs: prompt treatment can prevent serious complications and improve quality of life.

What can be done to limit complications?

Early detection: The best way to avoid complications is to diagnose cancer in its early stages. Consult a urologist as soon as any unusual symptoms appear.
Rigorous medical follow-up: If you’ve already been diagnosed, stick to the recommended appointments and treatments.
Healthy lifestyle: A balanced diet and regular exercise can support your overall health.

Conclusion

Complications associated with prostate cancer are often the result of uncontrolled disease progression. Recognizing early signs, such as bone pain, urinary problems or unexplained fatigue, is key to acting quickly. If you notice any of these symptoms, consult a specialist immediately.
