A Prostate Cancer Fact Sheet

September is Prostate Cancer Awareness Month.

What is prostate cancer?

Prostate cancer is typically a very slow growing tumor in the prostate gland, which is that part of the male reproductive system that produces the majority of seminal fluid that carries sperm. The prostate gland is the size of a walnut and is located beneath a man’s bladder and surrounds the upper part of the urethra, the tube that carries urine from the bladder.

Although prostate cancer progresses slowly, it is fatal if it spreads beyond the prostate gland itself to the lungs, bones or other distant tissues. This is called metastatic prostate cancer and there is no cure for it at this time.

Who is at risk for prostate cancer?

African-American and Jamaican men of African descent have the highest prostate-cancer incidence and mortality rates in the world.

Although scientists and doctors have been unable to pin down a reason for prostate cancer’s prevalence among men of African descent, there are some common factors that could increase one’s chances of developing the disease:

Age

  • Four out of five cases of prostate cancer are diagnosed in men over 65.
  • Less than 1% of men under 50 are diagnosed with the disease but it can be seen in men in their 30s and 40s.

Family History

  • Men with a family history of prostate cancer are more likely to develop the disease than the general population.

Dietary Factors

  • Men who consume a large amount of animal fat, especially from red meat are at risk.
  • Fat stimulates the production of testosterone that accelerates the growth of prostate cancer.
  • The disease is common in countries where meat and dairy products are dietary staples

Work history

  • Men who have worked in welding, battery manufacturing, rubber works, and workers frequently exposed to the metal cadmium seem to be abnormally vulnerable to prostate cancer.

Sedentary lifestyle

  • Lack of physical activity has also been cited as a risk factor.

What are the symptoms of prostate cancer?

All men are at risk of developing prostate cancer and the risk increases as the man grows older.

Prostate cancer frequently develops with no noticeable signs. It is a slow-growing disease but possible symptoms include:

  • Inability to urinate (difficulty starting or stopping)
  • Frequent urination(especially at night)
  • Pain or burning sensation when urinating or ejaculating
  • Blood or pus in the urine or semen
  • Persistent pain in the back, hips and pelvis, fatigue and anaemia may suggest prostate cancer even when other symptoms are absent.

How is prostate cancer treated?

Early detection is the best defense against prostate cancer and gives you and your doctor more time to fight the disease before it has a chance to spread. But once cancer becomes a reality, there are some treatment options you can discuss with your doctor.

Here are some options to consider if the disease is caught in the early stages:

  • Surgery
  • Radiation therapy – either external beam radiation or radioactive tumor seeding (brachytherapy)
  • Active surveillance, also known as expectant management or watchful waiting
  • Hormone therapy- usually reserved for older men too debilitated for active treatment and for treatment of men with more advanced disease.

Chemotherapy plays only a limited role in prostate cancer treatment. It’s reserved primarily for the treatment of men with advanced or recurrent prostate cancer that does not respond to hormone therapy.

How many men are affected with prostate cancer in Jamaica?

A new study on prostate cancer among Caribbean men of African descent has revealed there was a 270 per cent increase in the disease among Jamaican men between 1983 and 2007.

The results of the study, which are published in a soon-to-be-released book by scientist Dr Henry Lowe, also showed there have been significant increases in the number of men in their 40s and 50s who have been diagnosed with the disease.

Jamaica has a high incidence of prostate cancer – 304 per 100,000.
