The goal of chemotherapy is to destroy cancer cells. The decision to administer chemotherapy is made based on its potential for destroying these cells.  Determining which particular treatment is right for you depends on your general physical health, the type of cancer you have and at what stage it was diagnosed, and the goal of therapy that you and your doctor have agreed upon.
