Staging and Classification of Cancer

Cancer staging and classification are processes used by doctors to describe the size, location, and spread of a tumor. Staging determines how far the cancer has advanced, often using numbers from I to IV—where I is localized and IV indicates spreading to other parts of the body. Classification involves identifying the cancer type based on cell appearance and behavior, which guides treatment choices. Together, staging and classification help doctors assess prognosis, plan appropriate therapies, and monitor progress.
