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.

How is prostate cancer diagnosed?

Before diving into the diagnostic stages, find out what symptoms to look out for in our guide : What are the symptoms of prostate cancer?

Prostate cancer is one of the most common cancers in men, particularly after the age of 50. If you are experiencing symptoms such as urinary problems, or simply wish to undergo preventive screening, it is essential to understand the key steps involved in making an accurate diagnosis. Here’s a complete guide to the prostate cancer diagnosis process.

An abnormal psa level should lead to a consultation with a urologist.

The importance of early diagnosis

Prostate cancer is often asymptomatic in its early stages. Early diagnosis enables :

Rapid care.
Reduced risk of complications.
A wider choice of effective treatments.

If you experience symptoms such as difficulty in urinating, frequent urination at night or pelvic pain, it is vital to consult a specialist.

Steps in diagnosing prostate cancer

Initial consultation with a urologist

Analysis of symptoms: The urologist will ask questions about your family history, your lifestyle and your symptoms.
Assessment of risk factors: Age, heredity, ethnic origin and pre-existing medical conditions.

Clinical examination: rectal examination

This quick, painless examination allows the doctor to palpate the prostate via the rectum to detect any abnormalities (induration), enlargement).
Although uncomfortable for some, it remains a key screening tool.

Biological tests: PSA assay

PSA (Prostate Specific Antigen) is a protein produced by the prostate gland.
A high level may indicate a problem: inflammation, benign hypertrophy or cancer.
This test is often used in addition to the digital rectal examination (DRE).

Medical imaging to confirm anomalies

Multiparametric MRI:
- Advanced imaging to visualise the prostate and identify suspicious areas.
- It is particularly useful for guiding biopsies.
Transrectal ultrasound :
- Used to measure the size of the prostate and detect abnormalities.

Prostate biopsy: the definitive examination

If any abnormalities are detected, a biopsy is performed.
This involves taking samples of prostate tissue for laboratory analysis.
The results confirm the presence of cancer and determine its aggressiveness (Gleason score).

What to do after a diagnosis

Once the diagnosis has been made, several stages follow :

Determine the stage of the cancer (localised or metastatic).
Discuss treatment options tailored to your situation (surgery, radiotherapy, hormone therapy, etc.).

When should you go for screening?

From the age of 50: annual consultation for men with no risk factors.
From the age of 40-45: If you have a family history of prostate cancer or if you belong to a high-risk population (men of African origin, for example).
If you experience unusual urinary symptoms, even if you are younger.

Conclusion

Prostate cancer may be silent in its early stages, but signs such as urinary problems, pain or blood in the urine should be taken seriously. Early detection is essential to improve the chances of treatment and cure.
