What are the Stages of Cancer?

There are actually four stages of cancer with one being the earliest to stage 4 being the worst. Stage 1 starts with a tumor that the doctors have just found. As you progress through cancer you start to go to stage 2 and 3 and then when you get the worst cancer they say that is Stage 4.
