About Lung Cancer
The stage of your cancer is one of the most important factors in determining the best treatment option for you.
Staging of Non-small Cell Lung Cancer (NSCLC):
TNM is the staging system for NSCLC. “T” stands for tumor size, “N” stands for lymph nodes and “M” is for metastasis.
Tumor size is determined when the tumor is removed and sent to the pathologist
Lymph nodes are checked for evidence of tumor spread with CT scans, PET scans, lymph node biopsy or at the time of surgery, in a procedure called a lymph node dissection.
Metastasis, or spread to other organs, is assessed with bone scans, x-rays and CT scans.
Putting all this information together is called staging. Stages for NSCLC range from stage 0 to Stage IV. Your physician will tell you what stage of cancer you have.
Staging of Small Cell Lung Cancer (SCLC):
SCLC is generally divided into Limited-Stage Small Cell and Extensive-Stage Small Cell
Limited-Stage Small Cell Lung Cancer is found in one lung, the tissues between the lung and nearby lymph nodes only.
Extensive-Stage Small Cell Lung Cancer has spread from the lung in which it began into the other lung, or to other parts of the body.
