Study of prostate cancer

Prostate cancer - a disease which only affects men.

The prostate is in front of the rectum, and directly under the bladder. It is about the size of a walnut. There are thousands of tiny glands in the prostate - they produce a fluid that forms part of the semen. This fluid protects and nourishes the sperm. With the use of prostate muscle fibers, prostate is also involve in urine control. When the urethra pass through the prostate, these muscle fibers in the prostate contract and release, controlling the flow of urine flowing through the urethra.

In most of the cases, the prostate cancer starts in the gland cells. Most of the time prostate cancer is a slow progressing disease. Actually, many men die of old do not even know that they had prostate cancer. The patient only knows it when they carried out an autopsy with a doctor. Many cases shows that around 80% of the men died without knowing they have prostate cancer, even the doctors.

The main causes of prostate cancer are due to the following factors:

1.Age: age is considered as a primary factor, older man will have a higher risk of getting prostate cancer, it is rare among men under the age of 45, but much more common after the age of 50.

2.Diet: studies have shown that lack in vitamin D, and diet of  high in red meat may raise a person's chances of developing prostate cancer.

3.Sexual transmitted disease: men who had gonorrhea will have a higher chance of developing prostate cancer, according to research by the University of Michigan Health System.

4.Genetic factors: Genetic background may contribute to prostate cancer risk, as suggested by associations with race, family, and specific gene variants. Men who have a first-degree relative (father or brother) with prostate cancer have twice the risk of developing prostate cancer, and those with two first-degree relatives affected have a fivefold greater risk compared with men with no family history.
