1.1 Understanding the prostate

The prostate is a gland part of the male reproductive system; it is located below the bladder and above the rectum surrounding all the way around the first portion of the urethra below the bladder. It helps in the production of the seminal fluid that helps carry the sperm during ejaculation. One of the most common prostate problem is benign prostate growth that, over time, can compress the urethra and cause difficulty to urinate.

1.2 Risk factors for prostate cancer

No one knows exactly what causes the disease. However, it is known that it is not a contagious disease and that certain risk factors make some men more likely than others to develop the disease. Prostate cancer is the most common cancer in men and it is estimated that in the United States on average 1 in 6 men will develop the disease.

1.2.1 Age: Age is the most important factor, being rare before 45 years of age and more common after 60-65 years. Presents a progressively higher risk after 50 years of age.

1.2.2 Family History: If a first-degree relative (parent or sibling) has already developed the disease, the risk is higher.

1.2.3 Race: Prostate cancer is more common among black men in the United States, which may not occur in black men from other countries, they may be descendants of African tribes of different ethnicities. In the East, in general, is less frequent. However, this low incidence may not only have the racial factor as justification, since eastern migrating to the West and acquire local habits have progressively higher risk of prostate cancer in subsequent generations.

1.2.4 Diet: Some studies suggest that prostate cancer is related to diet rich in meat and animal fat, while diet rich in fruits and vegetables could have a certain protective factor.

Other factors such as benign prostate growth, obesity, smoking, having performed vasectomy, a viral infection of the prostate and lack of exercise are not considered risk factors and many others are being studied

1.3 Tracking

As prostate cancer localized or early stage usually causes no symptoms, you should try to find the disease before symptoms appear and for this it is recommended that the examination of the prostate by digital rectal examination and collection of a blood test, the PSA (Prostate Specific Antigen). Can be done annually in men above 50 years or above 40 years in those with increased risk factors.

1.3.1 Examination touch: Consists in the examination of the prostate through the rectum, is performed by the physician to identify hardened areas in the prostate and other changes that may be suspicious of cancer.
