Some facts about cancer:

| There are more than 100 different types of cancer |
All
cancers begin in cells, the body's basic unit of life. When cells become old or
damaged, they die and are replaced with new cells. However, sometimes this
orderly process goes wrong. The genetic material (DNA) of a cell can become
damaged or changed, producing mutations that affect normal cell growth and
division. When this happens, cells do not die when they should, and new cells
form when the body does not need them. The extra cells may form a mass of
tissue called a tumor.
