The sooner prostate cancer is treated, the better the outcome.
Cancer occurs when cells in the body divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant growths. These growths can invade nearby tissues. Cancer that has invaded nearby tissues can then spread to other parts of the body.
It is not clear exactly what causes these problems in the cells, but it is probably a combination of genetics and environment.
