What is Prostate Cancer?

Prostate cancer (medically known as prostate carcinoma) is a malignant tumor of the prostate gland, a small gland in the male body responsible for producing seminal fluid. It is the most common cancer in men in many Western countries. In its early stages, prostate cancer often causes no noticeable symptoms, making regular screening examinations particularly important.

Symptoms of Prostate Cancer

Early-stage prostate cancer frequently produces no or only very subtle symptoms. As the tumor grows, the following complaints may appear:

Urinary Symptoms

Frequent urination, especially at night (nocturia)
Weak or interrupted urine flow
Difficulty starting urination
Feeling of incomplete bladder emptying
Burning or pain during urination
Blood in the urine (hematuria)

Sexual Symptoms

Erectile dysfunction
Blood in semen (hematospermia)
Pain during ejaculation

Symptoms of Advanced Prostate Cancer

Persistent pain in the lower back, hips, or pelvis
Bone pain, especially if cancer has spread to the bones (metastases)
Unexplained weight loss
Persistent fatigue and exhaustion
Swelling in the legs due to lymphatic obstruction

Causes and Risk Factors

The exact causes of prostate cancer are not fully understood. However, the following risk factors are scientifically established:

Age: The risk increases significantly after the age of 50.
Family history: Men with a father or brother diagnosed with prostate cancer have an elevated risk.
Genetic factors: Certain gene mutations (e.g., BRCA2) increase the risk of developing the disease.
Diet: A high-fat, low-fiber diet is discussed as a potential contributing factor.
Ethnic background: Men of African descent have a statistically higher risk of developing prostate cancer.

Diagnosis

Since prostate cancer is often asymptomatic in its early stages, regular screening is essential. The key diagnostic methods include:

PSA test: Measurement of prostate-specific antigen (PSA) in the blood. Elevated levels may indicate prostate cancer but are not conclusive on their own.
Digital rectal examination (DRE): The physician manually palpates the prostate via the rectum to detect hardening or abnormalities.
Ultrasound (TRUS): Transrectal ultrasound to visualize the prostate gland.
MRI of the prostate: Magnetic resonance imaging for detailed assessment of suspicious areas.
Biopsy: Tissue sampling for microscopic analysis -- the only definitive confirmation of prostate cancer.

Treatment

Treatment of prostate cancer depends on the stage of the disease, the age of the patient, and individual factors. Common treatment options include:

Active surveillance: For slow-growing, localized tumors, close monitoring without immediate treatment may be appropriate.
Surgery (radical prostatectomy): Surgical removal of the prostate gland.
Radiation therapy: Use of radiation to destroy cancer cells (external beam or brachytherapy).
Hormone therapy (androgen deprivation therapy): Reduction of testosterone levels, which fuel tumor growth.
Chemotherapy: Used in advanced or metastatic stages.
Immunotherapy and targeted therapies: Modern approaches for tumors with specific molecular characteristics.

When to See a Doctor

Men aged 45 and older (or 40 and older with a family history) should attend regular prostate cancer screening. If symptoms such as frequent urination, blood in the urine, or persistent bone pain occur, a doctor should be consulted promptly. Early diagnosis significantly improves the chances of successful treatment.
