Prostate Cancer is one that develops in the prostate and can cause pain, difficulturination, erectile dysfunction, among other symptoms.
It often develops in patients over 50 years and is the second most common cancer in men. However, many men never have symptoms, undergo no therapy.
For many men diagnosed with prostate cancer can be frightening not only because they pledged their lives, but their sexuality. The possible consequences of treatment, which includes problems of bladder control and impotence, may worry some men more than the cancer itself.

Several risk factors have been established to develop the disease as:

• Age over 50 years.
• Diet high in meat, fat and dairy products.
• Physical inactivity and obesity
• Family history of cancer
• Infectious Agents and sexual activity.
• smoking

SIGNS AND SYMPTOMS
Most prostate cancers grow very slowly and persist for a long time without causing significant symptoms.
The presence of symptoms is indicative of who is in an advanced stage and these are: sudden need to urinate, difficulty or pain urinating, decreased andweak urine flow, frequent urination at night, blood in the urine, painful ejaculation,among others.

DIAGNOSIS

Detection is mainly performed by:
The blood test of prostate specific antigen (PSA).
Physical examination of the prostate gland (DRE).
Biopsy of the prostate with transrectal ultrasound, which is examined under a microscope.

TREATMENT
Treatment may include surgery, radiation, chemotherapy or a combination.

Surgery
Radical prostatectomy is surgery that is done with the intent to cure prostate cancer.


Radiotherapy
The radiation is low-grade cancer that is confined to the prostate or has onlyinvaded neighboring tissue.


Cryosurgery
Cryosurgery, also called cryotherapy or cryoablation, is sometimes used to treat localized prostate cancer by destroying tumor cells by freezing with a cryoprobe metal.


Androgenic hormonal blockade
. When levels of androgens (testosterone) are low, prostate cancers shrink andgrow more slowly. But hormone therapy does not cure cancer nor a substitutefor curative treatment.


Chemotherapy
This treatment is potentially effective in cancers that have metastasized (that have spread to distant organs of the prostate).


Palliative
Is to eliminate pain and other symptoms that diminish quality of life.
Because prostate cancer is a disease which mainly affects older men, many of them will die of other causes before the cancer can spread or cause symptoms.


Prevention
The mortality rate from this cancer has decreased due to early diagnosis. For this reason it is very important that people who are capable of contracting the disease to undergo medical examinations more frequently. It is important to remember the fact that man has a greater chance of developing the disease as they age.
