Prostate Cancer Causes and Risk Factors

Prostate cancer is the abnormal growth of cells in the prostate. The prostate is a small gland that exist only in men. It is located just below the bladder and just in front of the rectum in the lower pelvis.

The bladder acts as a storage reservoir for urine. When the bladder is emptied, the urine pass through a thin tube called urethra to the penis and then out. The beginning of the urethra as it leaves the bladder passed through directly the prostate. As the prostate enlarged, the urethra is pinched off, leaving a smaller tube to take urine from the bladder to the outside of the body through penis.

Prostate cancer is mostly a very slow progressing disease. In fact, many men die at old age, without ever knowing that they had prostate cancer, until an autopsy was performed. Several studies have shown that probably about 80% of all men in their eighties had prostate cancer when they died, but no one knows, even a doctor.

What Causes Prostate Cancer?

It is not exactly known the cause of prostate cancer, however there are some risk factors are linked to prostate cancer, including age, diet, obesity, family history, genetics, medicine, and race.

Some risk factors such as diet, obesity, can be controlled. While others, such as a person family history, race can not be changed.

Prostate Cancer Risk Factors

Age
Age is considered the major risk factor for prostate cancer. The chance of prostate cancer raise after a man reaches the age of 50. Nearly 2 of every 3 prostate cancers found in men over the age of 65.

Race
Prostate cancer is more common in African-American men than in men of other races. This may be due to a mixture of inherited genes and environmental factors, although its relationship is not clear.

Family history
Prostate cancer seems to run in some families. Men with family members who have been suffering from prostate cancer are more likely to get it themselves, especially if their relatives were young when they got the disease.

Diet
The exact role of diet on prostate cancer is unclear, but a studied has shown that men who eat lots of red meat or high-fat dairy products seem to have a higher chance of prostate cancer. These kinds of men also tend to eat fewer fruits and vegetables. Doctors are not sure which of these factors causes the risk of prostate cancer.

Genetic
Scientists have discovered some genes that seem to increase the risk of prostate cancer, but they probably account for only a small number of cases overall. Study for most of these genetic is not yet available, and more studies are required for this case.

Medication
Some studies found that there might be a link between the daily use of anti-inflammatory drugs and risk of prostate cancer. A study also found that statins, drugs that used to lower cholesterol, may lower the risk of prostate cancer.

Obesity
A study found a clear link between obesity and increased risk of prostate cancer, as well as a higher risk of metastasis and death among obese men who develop prostate cancer.
