25 interesting (and frightening) cancer-related facts

What is Cancer?

Illustration of cancer development and spread in the human body.

Cancer is the name given to a set of more than 100 diseases that have in common the disorderly growth of cells that invade tissues and organs, and can spread to other regions of the body. Healthy cells multiply when needed and die when the body no longer needs them. The cancer occurs when the increase in body cells is out of control, and they divide very fast. It can also occur when the cell "forgets" to die.
