Prostate Cancer – Incidence, Symptoms, Causation, Diagnosis, Treatment and Prognosis

Prostatic cancer is the most common cancer in men over the age of fifty.

Adenocarcinoma is the most common form.

Prostate cancers seldom produce symptoms until the cancer is in the advanced stage so early diagnosis is essential as in the early stages the disease is curable.

Location and Function
The Prostate is an organ forming part of the male reproductive system. It is located immediately below the bladder and just in front of the bowel. Its main function is to produce fluid which protects and enriches sperm.

In younger men the prostate is about the size of a walnut. It is dough nut shaped as it surrounds the beginning of the urethra, the tube that conveys urine from the bladder to the penis. The nerves that control erections surround the prostate.

Signs and Symptoms

o Waking frequently at night to urinate
o Sudden or urgent need to urinate
o Difficulty in starting to urinate
o Slow flow of urine and difficulty in stopping
o Discomfort when urinating
o Painful ejaculation
o Blood in the urine or semen
o Decrease in libido (sex urge)
o Reduced ability to get an erection

Most men tend to accept the onset of one or more of these symptoms as being a natural consequence of aging. However, anyone experiencing any of the above symptoms is advised to consult a doctor without delay. Early expert diagnosis and treatment is important and may avert potentially serious health consequences.

Prostate cancer is usually one of the slower growing cancers. In the past, it was most frequently encountered in men over 70, and many of those men died of other causes before their prostate cancer could kill them. This led to the old saying “most prostate protocol reviews 2021 men die with, not of, prostate cancer”.

However, that is certainly is not true today. Three developments have changed things considerably:

o Men are living longer, giving the cancer more time to spread beyond the prostate, with potentially fatal consequences.
o More men in their early sixties, fifties and even forties are being detected with prostate cancer. Earlier on-set, combined with the greater male life expectancy, means those cancers have more time to spread and become life-threatening unless diagnosed and treated.
o Prostate cancer in younger men often tends to be more aggressive and hence more life-threatening within a shorter time.

Risk Factors and Testing
Risk factors for prostate cancer include diets high in fat and low in vegetables. Risk factors include age; 75% of cases are in men over 65 years. Prostate cancer is most often discovered by physical examination or by screening blood tests, such as the PSA (prostate specific antigen) test.

The PSA test measures the blood level of prostate-specific antigen, an enzyme produced by the prostate. The risk of prostate cancer increases with increasing PSA levels.

The majority of men who reach age 85, in fact, have cancerous prostate cells, but the disease is developing so gradually that it never threatens their quality of life.

Genetic factors play a role, particularly for families in whom the diagnosis is made in men under 60 years of age, and the risk of prostate cancer rises with the number of close relatives who have the disease.
