The prostate is a male gland located below the bladder and around the urethra. Its main function is to secrete part of the seminal fluid that helps keep sperm alive and active. Its size may vary over time and usually increases in size as we age, especially over 40 or 50 years.
The prostate gland has a complex structure. 30% is fibromuscular tissue (composed of muscle and fibrous tissue), and 70% glandular elements that produce prostate fluid. It is also wrapped in a thin layer called the prostate capsule which separates it from adjacent tissues.
The glandular structure of the prostate can be divided into different zones. The main areas are:
- Transitional zone: Where the prostate adenoma (benign tumor) usually develops.
- Central zone: Relatively resistant to the development of pathologies.
- Peripheral zone: This zone is where most of the cancerous processes are generated.
