The prostate gland is the main responsible in keeping the sexual health of men active. Without it, it would be difficult for them to respond to the demands from the natural law of their bodies. But there are times that the prostate gland is actually destroyed and prostate cancer might emerge. Men that are identified as having prostate cancer are recommended to endure immediately cancer treatments for that cancer regression to be easily detected and referral to further treatments could be done and suitable actions can be prescribed. Setting up is the process of knowing the regression from the prostate cancer and how much it had spread inside the patient’s body. This is essential since the specialists should know if the disease experienced spread only in the prostate gland or also to other areas from the body. Staging also helps detecting the stage of the prostate cancer contained in a male individual.
Usually, stages of prostate cancer have four stages from Stage 1 to Stage 4 and sometime even recurrent situations might happen. In the event that the prostate cancer has reached Stage 4, there is now possible that the disease will spread not only in the prostate gland but it can also affect the areas outside the prostate gland especially those tissue and lymph nodes and even other organs in the advanced stage from the disease. 
The Gleacon’s Score technique is one of the most common procedures done in testing the stage of a particular prostate tissue. The sample prostate tissue is place and observed under a microscope and eventually the tissue is given a score between two to ten. When a prostate cells got a score or even 2, this means that there is a lesser risk of the prostate cancer to spread in a male’s body whilst if the prostate tissue gets a high score, it means a higher risk of ability from the prostate cancer to spread due to cell abnormalities. Other experts use the nodes, tumor and metatesis program in detecting the stages of prostate cancer. With this particular approach, subsystems might be present for a thorough observation and detection. 
Stage I of prostate cancer is often microscopic in size and is just present in the prostate gland. This generally get a low score in the Gleacon’s Score testing. Stage 2 prostate cancer is still present in the prostate but it has grown right into a bigger form. It is in some way more detectable through DRE compared to the Stage I. when cancer of the prostate reaches Stage III, the disease is now big enough to grow as well as mutate outside the prostate gland but does not affect the actual lymph nodes, tissues and other organs round the prostate. The cancer cells are now able to producing semen. When Phase IV is reached, the condition is now capable of destructing the other internal organs outside the prostate gland commonly the rectum and the bladder. When the illness gets advanced, the entire entire body might be affected and it will be difficult to control the spread and mutation of the prostate cancer cells.
