![]() ![]() Exposure to substances in the workplace such as asbestos.Radiation to the chest as a treatment for other cancers.Secondhand cigarette smoke or other tobacco smoke.Environmental risk factors, such as exposure to the gas radon.( 11)Īccording to the Centers for Disease Control and Prevention (CDC), other factors that raise lung cancer risk include: ( 12) ( 10)Ĭigar smoking and pipe smoking are almost as likely to cause cancer as cigarette smoking, according to the American Cancer Society. The National Cancer Institute says that tobacco smoking causes about 9 out of 10 cases of lung cancer in men and roughly 8 out of 10 cases of lung cancer in women. Tobacco smoking is the number one risk factor for lung cancer. Learn More About the Stages of Lung Cancer The majority of people with SCLC have extensive disease when diagnosed. Extensive Stage The cancer has spread widely throughout the lung, to the other lung, to lymph nodes on both sides of the chest, or to other parts of the body.If lymph nodes are affected, they also are typically on that side of the chest. Limited Stage The cancer is only on one side of the chest.Small-cell lung cancer is generally divided into two stages, according to the American Cancer Society : ( 7) Main Stages of Small-Cell Lung Cancer (SCLC) Stage 4 The cancer has spread to both lungs, to fluid surrounding the lung or the heart, or to more distant sites in the body, such as the brain, bones, and liver.Stage 3 The cancer is larger than 7 cm (about 3 inches) or it has grown large and spread to the lymph nodes in the middle of the chest.Stage 2 The cancer is larger than 4 cm or has spread to nearby lymph nodes.The tumor is smaller than 4 centimeters (cm) across - about 1.5 inches. Stage 1 The cancer is only located in the lungs and hasn’t spread to any lymph nodes.It’s sometimes known as “carcinoma in situ.” Stage 0 The cancer is very small and hasn’t spread beyond the inner lining of the lungs.The breakdown here simplifies the criteria: ( 5, 6) In general, the higher the number, the more advanced the disease. ![]() NSCLC may proceed from stage 0 to stage 4 lung cancer, with many substages. Main Stages of Non-Small-Cell Lung Cancer (NSCLC) Different types of lung cancer are staged differently. Staging is an important part of determining treatment. ![]() After doctors have diagnosed lung cancer and identified the type, the next step is staging - ascertaining the size and extent of the tumor and determining whether the cancer has spread and, if so, how far. ![]()
