Staging of lung cancer

Staging of lung cancer determines how advanced the disease is and how far it has spread. It typically ranges from Stage 0 (very early, localized cancer) to Stage IV (advanced cancer that has spread to other organs). Staging involves imaging tests and sometimes biopsies to assess the tumor's size, lymph node involvement, and metastasis. This information helps doctors decide on the best treatment options and predict the patient’s prognosis. Understanding the stage is crucial for planning effective therapy and managing the disease appropriately.
