1.0 INTRODUCTION
1.1 CANCER
This is a disease that begins in the cells of the body in a normal situation, the cell grow and divide as the body needs them. This orderly process is distorted when new cell form in the body and the body did not need them and the old body did not need and the old cell do not die when the they should. The extra cell lumps together to form a growth or tumor (Brown et al 2006).
Cancer occurs when cellular reproduction process growth goes out of control. In other words, cancer is a disease that is characterized by the uncontrolled uncoordinated and undesirable Cells continues to grow and divided for their whole lives, replicating into more harmful cells. The abnormal growth and division found in cancer cells is caused by damage in these cells. Deoxynobonucleic acid (DNA) (genetic materials inside cells that determine cellular characteristics and functions). Cancerous cell can travel to other part of the body through the blood stream or lymph vessels. This process metastatsis (Turner et al, 2006).
1.12 PROSTATE
Prostate is part of male reproductive system that help to make and store seminal fluid in adult men. A typical prostrate is about three centimeter long and weight about twenty grams. Williams et al (2010),
It is located in the pelvis, under the lunar bladder and in front of the urethra, the tube carries urine during ejaculation.
1.12 PROSTRATE CANCER
This is a form of cancer that develops in the prostrate, a gland in the male reproductive system. It wraps around the urethra, the tube that carries urine out of the body. Most prostrate cancer is slow growing, however, they are caused of aggressive prostrate cancer, the cancer may metastasize (spread) from the prostrate to other part of the body. : Gabriel (2009)
The development of prostrate cancer is a slow process, typically taking from between two to four years to double in size. This slow growth often long time without detection cancers growth is as result of abnormal cell growth out of control.
1.2 TYPES OF PROSTRATE CANCER
There are basically three types of prostrate cancer. Salomon et al (2009).
1.21 ADEMOMA CARCINOMA PROSTRATE CANCER
This is the most common site of origin of prostrate cancer. It occurs in the peripheral urine / the main glanclular) zone of the prostrate. The term adenoma carcinoma can be spit up to drive its meaning adenoma means pertaining to a gland whilst carcinoma relates to cancer that develops in epithelial cells. Brown (2009).
1.22 SMALL CELL CARICINOMA PROSTRATE CANCER: This is the kind of cancer that made up of small cell, round cells and typically forms at nerve cells. Small cells carcinoma is very aggressive in nature and as it does not lead to an increase in prostrate specific antigen. It can be somehow harder to detect that Adenoma carcinoma (Ekane, S et al (2001).
2.23 SQUAMOUS CELL CARCINOMA
According to this is a non glandular cancer like small cell carcinoma. There is no increase in prostrate specific antigen when this is present. Squamous cell carcinoma is very aggressive. Gabriel (2009)
1.3 DISTRIBUTION OF PROSTRATE CANCER
The rate of prostrate concern widely across the world, although the rate very widely between counties it is least common in South and East Asia, more common in Europe and most common in the United State. Prostrate cancer develops primarily in more over fifty, it is the most common type of cancer in men in the Africa (Gabrie 2009).
The distribution rates of prostrate cancer were assessed with each region of all prostrate models, and the difference between the rates was statistically analyzed using mental Hansel Methodology.
There was a statistically significant higher distribution rate of cancer in the posterior half where it is (75.9%) compared to the anterior half which is (60.4%) and the base regions which is (55.9%). And in these the statistically which is (65.9%). Samuel et al (2006)
