Cancer develops when normal cells in the body undergo genetic mutations that lead to uncontrolled growth and division. The human body comprises trillions of cells; each cell contains DNA, which serves as the instructions for the cell's functions. When mutations occur in specific genes, they can disrupt the normal regulation of cell growth and division, forming a cancerous mass of cells.

Prostate is a reproductive gland in males; it is relatively small organ and is located under the bladder. Prostate cancer is caused by the uncontrolled division of mutated prostate cells. These cancer cells form a tumor and obstruct the normal function of the prostate and the bladder. It is rare in men younger than 40. Risk factors for developing prostate cancer include being over 65 years of age, family history and some genetic changes.
