Prostate Cancer Symptoms: Early and Advanced Stage Signs

Prostate cancer is the second most common cancer in men, after lung cancer. Approximately 1.4 million new cases are diagnosed worldwide each year. It is often asymptomatic in the early stage — a characteristic that is both dangerous and advantageous: when caught early through screening programs, the vast majority of cases are treatable. In this article, we cover the symptoms of prostate cancer, which symptoms should raise concern, and the importance of screening.

Why Does Prostate Cancer Cause No Symptoms in the Early Stage?

The vast majority of prostate cancers originate in the outer region of the gland (the peripheral zone). This area does not directly compress the urethra, so urinary flow is unaffected for a long time. Prostate cancer that does produce symptoms is usually locally advanced or metastatic.

For this reason, the belief that “my prostate is fine because I have no symptoms” is misleading. Screening is the only reliable path to early diagnosis.

Prostate Cancer Symptoms: By Stage

Early Stage (Localized Disease)

Most often no symptoms are present. Rarely observed findings include:

Elevated PSA value detected during screening (with no symptoms)
Hardness or nodule on digital rectal examination
Slight slowing of urine flow (may be confused with BPH)

Locally Advanced Stage

When the tumor begins to compress the urethra or bladder neck:

Symptom	Description
Weak or interrupted urine stream	Urethral compression
Frequent and urgent urination	Bladder irritation
Waking at night to urinate	Nocturia
Hematuria	Blood in urine
Hematospermia	Blood in semen
Ejaculatory pain	Seminal vesicle involvement
Erectile dysfunction	Nerve involvement

Important: The majority of these symptoms also occur in benign conditions such as BPH or prostatitis. The presence of symptoms alone does not establish a diagnosis of cancer.

Advanced Stage / Metastatic Disease

When cancer has spread to bones, lymph nodes, or distant organs:

Bone pain: Most commonly in the lower back, hips, thighs, ribs — pain that worsens at night
Leg swelling or numbness: Pelvic lymph node involvement
Weight loss and loss of appetite
Extreme fatigue
Signs of spinal cord compression: Leg weakness, loss of bladder/bowel control (oncological emergency)
Pathological fracture: Fracture from minimal trauma due to bone metastasis

Elevated PSA: What Does It Mean?

PSA (Prostate-Specific Antigen) alone is not a diagnostic tool for cancer; however, it is the most important screening marker.

PSA Value (ng/mL)	Interpretation
< 2.5	Low risk (under age 50)
2.5–4	Borderline; should be assessed based on age
4–10	Suspicious; biopsy evaluation warranted
> 10	High risk; biopsy recommended

Elevated PSA may also occur in the following conditions (false positive):

BPH (benign prostatic hyperplasia)
Prostatitis (prostate inflammation)
Urinary tract infection
Recent digital rectal examination
After prostate biopsy
Intense cycling

PSA Derivatives: More Refined Assessment

Derivative	Purpose
Free PSA / Total PSA ratio	A lower ratio increases cancer risk
PSA density	PSA / prostate volume; corrects for enlarged prostate
PSA velocity	An increase of more than 0.75 ng/mL per year is suspicious
PSA doubling time	Used to assess recurrence after treatment

Diagnostic Process

In the setting of elevated PSA or an abnormal DRE, the following steps are taken:

Repeat PSA — after 4–6 weeks (to rule out transient elevations)
Free PSA / Total PSA ratio
MRI (multiparametric mpMRI) — imaging of suspicious areas
Prostate biopsy — TRUS-guided or MRI-fusion biopsy
Gleason score / ISUP grade — tissue pathology
Staging imaging — bone scintigraphy, PSMA PET-CT (when indicated)

Gleason / ISUP Scoring

ISUP Grade	Gleason Score	Risk
Grade 1	3+3=6	Low
Grade 2	3+4=7	Intermediate-favorable
Grade 3	4+3=7	Intermediate-unfavorable
Grade 4	4+4=8	High
Grade 5	9–10	Very high

Risk Factors

Factor	Risk Level
Advanced age (50+)	Strongest risk factor
Family history (first-degree relative)	2–3 times increased risk
BRCA2 mutation	5–8 times increased risk
Men of African ancestry	Higher incidence
Obesity	Increased risk of aggressive cancer
Red meat and saturated fat	Weak association

Screening Recommendations

Group	Recommendation
Average risk, age 50+	PSA + DRE every 1–2 years
Family history of prostate cancer, age 45+	Early screening
BRCA2 mutation, age 40+	Early screening
Over age 75	Individual decision; benefits and risks should be discussed

The Turkish Urology Association recommends annual PSA screening for men between the ages of 50 and 70.

Treatment Options (Summary)

Stage	Options
Low-risk localized	Active surveillance, radical prostatectomy, radiotherapy
Intermediate-to-high-risk localized	Radical prostatectomy, radiotherapy ± ADT
Locally advanced	Radiotherapy + ADT
Metastatic hormone-sensitive	ADT ± chemotherapy, ARSI (enzalutamide, abiraterone)
Castration-resistant	ARSI, chemotherapy (docetaxel), PSMA radioligand therapy

Frequently Asked Questions

When do prostate cancer symptoms appear? They are usually absent until the locally advanced or metastatic stage. This is why regular PSA screening is life-saving.

My PSA came back at 5 ng/mL — does that mean I have cancer? When PSA is in the 4–10 range, cancer is detected in approximately 25–35% of cases. Definitive diagnosis requires mpMRI and, if necessary, a biopsy. PSA alone is not a diagnostic tool.

Does prostate cancer cause pain? Not in the early stages. Pain in the lower back, hips, and bones begins when bone metastasis develops.

Is prostate cancer treatable? The 10-year survival rate for localized-stage disease is above 95%. Cancer detected early is largely treatable.

Is hematospermia (blood in semen) a sign of prostate cancer? Hematospermia most commonly originates from prostatitis or seminal vesicle causes; isolated hematospermia is rarely a sign of cancer. However, if recurrent, urological evaluation is required.

Is prostate cancer hereditary? There is a strong familial component. Having a first-degree relative with prostate cancer increases the risk 2–3 fold. BRCA1/2 mutations in particular raise the risk of aggressive cancer.

How fast does prostate cancer progress? The majority progress slowly and remain clinically silent for years. This varies by Gleason/ISUP grade; low-grade cancers can be monitored, while high-grade cancers progress rapidly.

What happens to sexual function after radical prostatectomy? With nerve-sparing surgery, the rate of erectile dysfunction is 30–60%; this may partially recover over time. Retrograde ejaculation is unavoidable.
