Staging is used to determine the spread of cancer, and is based on whether or not the cancer is contained within the lungs or if it has spread elsewhere to lymph nodes and/or other organs. The main stages of lung cancer are stage 1 to stage 4, from least advanced to advanced, respectively. Knowing and understanding the stage of your lung cancer is vital, as your treatment options will be shaped by the stage and progressive of your cancer.
Unfortunately, the majority of patients are already at an advanced stage of lung cancer (stage 3 or 4) when they are diagnosed, making treatment options more difficult. For more information about the staging of lung cancer click here.
