There are two main types of lung cancer, called non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging is a way of describing the size of the cancer, where it’s located and if and how far it has spread.
The board-certified pulmonologists at CHI Saint Joseph Health use advanced diagnostic testing to stage the cancer and develop a personalized lung cancer treatment plan, if needed.
Keep in mind that lung cancer symptoms often don’t show until the disease has progressed. That’s why we also offer low-dose CT scans to catch lung cancer in its earliest and most treatable stage. The test is fast, simple and could save your life.

Non-small cell lung cancer accounts for about 85% of lung cancers, and includes squamous cell carcinoma, large cell carcinoma and adenocarcinoma, the most common form of the disease among both men and women. It mainly occurs in people who smoke, or used to, though it’s also the leading type of lung cancer among non-smokers.
The main way your doctor will stage non-small lung cancer is called the TNM system:
These letters are then paired with a number to determine the severity of the tumor and how much it’s spread:
If non-small cell lung cancer is detected early enough, surgery is usually the first option. If the tumor is completely removed and nearby lymph nodes do not show cancer, no further treatment may be required.
For more advanced tumors, patients may need post-operative treatment with chemotherapy, radiation therapy or both. Sometimes, radiation therapy and/or chemotherapy may be recommended before surgery, to help shrink the tumor so it can be removed.
Small cell lung cancer accounts for the remaining 15 percent of lung cancers. It is the most aggressive form of the disease, often spreading quickly to the liver, bone or brain.
The TNM system may also be used to stage small cell lung cancer, but it’s generally measured in two categories:
Small cell lung cancer treatment typically does not involve surgery except in rare circumstances. Most patients are treated with a combination of chemotherapy and radiation therapy. Because small cell lung cancer often spreads to the brain, treatment may also include a low dose of radiation therapy to the brain, even if there are no tumors visible on a CT scan or MRI. This has shown to improve survival for patients with small cell lung cancer.
