What is the importance of cancer staging?
Cancer staging provides helpful information for both patients and doctors: The stage suggests the most likely outcome. Knowing the stage gives an educated estimate of life expectancy and the chance of a cure. Treatment will be planned and recommended based on the stage of the cancer.
