Cancer is a disorder in which the body’s cells proliferate uncontrollably. Prostate cancer occurs when cancer begins in the prostate. Prostate cancer is the most cancer in excluding skin cancer.
What Exactly Is the Prostate?
The prostate is a component of the male reproductive system that also comprises the penis, seminal vesicles, and testicles. The prostate is situated beneath the bladder and in front of the rectum. It is around the size of a walnut and wraps around the urethra. (the tube that empties urine from the bladder). It generates fluid, which is a component of sperm.
The prostate grows in size as a guy gets older. This can constrict the urethra and reduce urine flow. This condition is known as benign prostatic hyperplasia and is not the same as prostate cancer. Men may also have other interests.
The prostate (not prostrate) is a tiny, rubbery gland found deep inside the groin, between the base of the penis and the rectum. It is necessary for reproduction because it produces seminal fluid (semen), which is mixed with sperm from the testes. Seminal fluid aids sperm to travel and survival.
The more you understand about the prostate, its normal development and function, where it is placed, and what it is related to, the more you will be able to grasp how prostate cancer grows and influences a man’s life over time—whether due to cancer growth or as a result of treatments.a
Seminal vesicles are rabbit-eared structures that sit on top of the prostate and store and produce a significant amount of ejaculate.
The neurovascular bundle is a network of nerves and blood arteries that runs along each side of the prostate and regulates erectile function. These nerves go a short distance away from the prostate in some men, whereas they adhere to the prostate in others. Their specific position has no effect on prostate function and does not contribute to prostate cancer when it arises.
The bladder expands as it fills with urine, much like a balloon. The urethra, a small tube that links to the bladder, travels through the center of the prostate and down the length of the penis, removing both urine and sperm. The bladder is drained via the hose.
The rectum is the bottom end of the intestines and links to the anus. It is located just behind the prostate.
Zones of the Prostate
The prostate is separated into anatomic zones or areas. The vast majority of prostate cancers begin in the peripheral zone (the rear of the prostate), near the rectum. That is why, in addition to the PSA blood test, a digital rectal exam (DRE), in which a doctor examines the prostate by inserting a gloved finger into the rectum, is a popular and beneficial screening test.
The urinary difficulty is not usually a symptom of prostate cancer. Lower urinary tract symptoms are most commonly caused by Benign Prostatic Hypertrophy (BPH), a non-cancerous prostate disorder that originates from the transition zone that surrounds the urethra, or urine tube. (closer to the middle of the prostate).
What Functions Does the Prostate Serve?
The prostate is not required for life, but it is necessary for reproduction. Healthy sperm has the ideal consistency and habitat for transit and survival, as well as fertilization. Semen contains enzymes such as PSA (which is frequently examined as part of prostate cancer screening) as well as other components produced by the seminal vesicles and prostate such as zinc, citrate, and fructose. (that actually gives sperm energy to make the journey to the egg). Semen also contains antibacterial and antiviral chemicals that may protect the urinary system and sperm from bacteria and other diseases.
During adolescence, the prostate grows under the direction of the male hormone testosterone and its metabolite dihydrotestosterone. (DHT). Testosterone is predominantly produced in the testes, although it is also produced in minor amounts in the adrenal glands located above the kidneys.
