Cancer is known as a condition, which is caused by the uncontrolled division of cells. As humans, we have tumor suppressor genes which actually prevent cancer by slowing down the growth of cells or stopping the growth altogether.
In a normal human body, cells divide at a certain rate in order to place old dying cells, while maintaining homeostasis. When there is a change in DNA, and the tumor suppressor gene is defective, cells begin to grow and divide uncontrollably (Mader, 2007).
When cancer cells divide, they require food and water, and even attracts blood vessels, when cells grow and divide uncontrollably the cancer cells begin to compete with normal somatic cells (Dollinger, 2002).
