All cancers begins in cells, the body's basis unit of life to understand cancer it's helpful to know what happens when normal cells becomes cancer cells.The body is made up of many types of cells. These cells grow and divide in a controlled way to produced more cells as they are needed to keep the body healthy. When cells become old or dangered they die and replaced in new cells. But sometimes this orderly process goes wrong. The genetic material of a cell can become damaged or changed producing mutations that affect normal cell growth and division.
