Stage 1 refers to the initial phase of a process or development. In various contexts, such as project management or child development, it often involves the foundational steps that set the stage for future progress. This stage typically includes planning, assessment, and the establishment of goals. In the context of cancer staging, Stage 1 indicates that the cancer is localized and has not spread to nearby lymph nodes or other parts of the body. Early detection at this stage often leads to better treatment outcomes and a higher chance of recovery.
