![]() Extensive stage SCLC is widespread throughout one lung or has spread to the other lung, lymph nodes on the opposite side of the lung, or to other parts of the body.Limited stage SCLC is confined to one lung and can sometimes be in the lymph nodes in the middle of the chest or above the collar bone on the same side.This is based on whether the area can be treated with a single radiation field. While providers now use stages I through IV for small cell lung cancer, you might also hear it described as limited or extensive stage. Stage IV: Cancer has spread to the other lung, the fluid around the lung, the fluid around the heart or distant organs.Stage III: Cancer is larger than Stage II, has spread to nearby lymph nodes or structures or there’s more than one tumor in a different lobe of the same lung.Stage II: Cancer is larger than Stage I, has spread to lymph nodes inside the lung, or there’s more than one tumor in the same lobe of the lung.Stage I: Cancer hasn’t spread outside the lung.It hasn’t spread to other parts of the lung or outside of the lung. Stage 0 (in-situ): Cancer is in the top lining of the lung or bronchus.For instance, the primary tumor in a Stage III cancer could be smaller than in a Stage II cancer, but other factors put it at a more advanced stage. Lung cancer stagingĮach stage has several combinations of size and spread that can fall into that category. Each type of cancer has its own guidelines for staging. What are the stages of lung cancer?Ĭancer is usually staged based on the size of the initial tumor, how far or deep into the surrounding tissue it goes, and whether it’s spread to lymph nodes or other organs. These are treated differently and usually aren’t referred to as lung cancer. Other types of cancer can start in or around your lungs, including lymphomas (cancer in your lymph nodes), sarcomas (cancer in your bones or soft tissue) and pleural mesothelioma (cancer in the lining of your lungs). Specific types of SCLC include small cell carcinoma (also called oat cell carcinoma) and combined small cell carcinoma. It’s often found as a relatively small lung tumor that’s already spread to other parts of your body. Small cell lung cancer (SCLC) grows more quickly and is harder to treat than NSCLC. Adenosquamous carcinoma and sarcomatoid carcinoma are two less common types of NSCLC. Common types include adenocarcinoma and squamous cell carcinoma. It accounts for over 80% of lung cancer cases. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. There are many cancers that affect the lungs, but we usually use the term “lung cancer” for two main kinds: non-small cell lung cancer and small cell lung cancer. Cancers that start in other places and move to your lungs are usually named for where they start (your healthcare provider may refer to this as cancer that’s metastatic to your lungs). Lung cancer is the name for cancers that start in your lungs - usually in the airways ( bronchi or bronchioles) or small air sacs (alveoli). Damaged cells dividing uncontrollably create masses, or tumors, of tissue that eventually keep your organs from working properly. ![]() But sometimes, they get changes (mutations) that cause them to keep making more of themselves when they shouldn’t. Your cells divide and make more copies of themselves as a part of their normal function. Lung cancer is a disease caused by uncontrolled cell division in your lungs. Lung cancer usually starts in the airways (bronchi or bronchioles) or small air sacs (alveoli) of your lungs. ![]()
