Prostate median lobe cancer is a specific type of prostate cancer that affects the median lobe of the prostate gland. This guide provides detailed yet straightforward information about its definitions, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention strategies, and frequently asked questions.
Prostate median lobe cancer refers to cancerous growths specifically located in the median lobe of the prostate gland. The prostate is a small gland in males, part of the reproductive system, that produces seminal fluid. The median lobe is the central part of the prostate, situated between the two other lobes. When cancer develops in this area, it can affect urinary and sexual functions due to its location.
Pathophysiology
Structure
The prostate gland consists of three main lobes: the right lobe, left lobe, and the median (middle) lobe. The median lobe projects into the bladder and surrounds the urethra, which carries urine from the bladder out of the body. The structure of the median lobe makes it a common site for benign prostatic hyperplasia (BPH) and, less commonly, prostate cancer.
Blood Supply
The prostate receives its blood supply primarily from the inferior vesical artery, which branches off from the internal iliac artery. Adequate blood flow is crucial for delivering oxygen and nutrients to the prostate tissues. In cancerous growths, the blood supply can become irregular, contributing to tumor growth and the potential spread of cancer cells.
Nerve Supply
The prostate is innervated by the autonomic nervous system, which controls involuntary bodily functions. Nerves around the prostate play a role in erectile function and urinary control. Cancer in the median lobe can disrupt these nerves, leading to symptoms like erectile dysfunction or urinary difficulties.
Types of Prostate Median Lobe Cancer
Prostate cancer is generally categorized based on how it looks under a microscope and its genetic makeup. While cancer in the median lobe is not a separate type, it can be classified according to standard prostate cancer types:
- Adenocarcinoma: The most common type, originating from glandular cells.
- Ductal Carcinoma: A rare form that starts in the ducts of the prostate.
- Small Cell Carcinoma: An aggressive type that begins in neuroendocrine cells.
- Squamous Cell Carcinoma: A very rare type that starts in flat cells lining the prostate.
Causes of Prostate Median Lobe Cancer
Prostate cancer, including in the median lobe, results from genetic and environmental factors. Here are 20 potential causes and risk factors:
