Prostate cancer is a significant health concern affecting many men worldwide. This guide provides an in-depth look at prostate cancer, focusing on the prostate lobes, its pathophysiology, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention strategies, when to seek medical help, and frequently asked questions.
Prostate cancer occurs in the prostate gland, a small walnut-shaped gland in men that produces seminal fluid, which nourishes and transports sperm. It’s one of the most common cancers among men, especially those over 50. Early detection is crucial for effective treatment.
Prostate Lobes and Anatomy
The prostate gland is divided into several zones, often referred to as lobes. Understanding these lobes helps in diagnosing and treating prostate cancer.
- Peripheral Zone: The largest zone, located towards the back of the prostate, where most cancers originate.
- Central Zone: Surrounds the ejaculatory ducts; less commonly affected by cancer.
- Transition Zone: Surrounds the urethra; often affected by benign prostatic hyperplasia (BPH).
Pathophysiology of Prostate Cancer
Structure
The prostate is composed of glandular and fibromuscular tissues. Cancer typically starts in the glandular cells lining the prostate ducts.
Blood Supply
The prostate receives blood through the superior and inferior vesical arteries, which branch from the internal iliac arteries. Adequate blood supply is essential for the growth and spread of cancer cells.
Nerve Supply
The prostate is innervated by autonomic nerves from the pelvic plexus, which control functions like ejaculation. Cancer can affect these nerves, leading to symptoms like erectile dysfunction.
Types of Prostate Cancer
- Adenocarcinoma: The most common type, originating in gland cells.
- Small Cell Carcinoma: A rare and aggressive form.
- Transitional Cell Carcinoma: Begins in the urethra and spreads to the prostate.
- Squamous Cell Carcinoma: Extremely rare, starting in the flat cells lining the prostate.
Causes of Prostate Cancer
While the exact cause isn’t known, several factors can increase the risk:
- Age: Risk increases after 50.
- Family History: Having relatives with prostate cancer.
- Genetics: Certain gene mutations.

- Infections: Certain viral infections.
- Immune System: Weakened immune function.
- Environmental Factors: Exposure to certain toxins.
- Dietary Supplements: Some may increase risk.
- Age at First Birth: Later age may increase risk.
- Sexual History: Early sexual activity may have a protective effect.
