Lung cancer stages

Making an educated treatment decision begins with the stage, or progression, of the disease. Using the results from your diagnostic tests, your care team at Cancer Treatment Centers of America (CTCA) will develop an appropriate treatment plan for you.

If you have been recently diagnosed, we will review your pathology to confirm you have received the correct diagnosis and staging information, and develop a personalized treatment plan. If you have a recurrence, we will perform comprehensive testing and identify a treatment approach that is suited to your needs.

Cancer Staging

Stage 0 Non-Small Cell Lung Cancer

Stage 0 non-small cell lung cancer, also known as carcinoma in situ, is another early stage of lung cancer that has not spread beyond the lungs. With this stage, only a few layers of cancer cell have been discovered in one local area, and have not broken through the top lining of the lung.

Since the cancer has not spread, the prognosis is similar to that of the occult stage, with a five-year survival rate of 60 – 80 percent.

TNM categories of stage 0

A stage 0 lung cancer diagnosis occurs in conjunction with the following TNM categories:

  • Tis: Cancer is found only in the top layers of cells lining the air passages, and has not extended deeper into the lung tissue.
  • N0: The cancer has not spread to the lymph nodes.
  • M0: There has been no spreading to distant organs or other areas.

What is stage 0 lung cancer?

This stage of lung cancer often does not present symptoms, and so the discovery of the cancer can occur when evaluating other symptoms or health issues. Symptoms that might appear are a persistent cough, shortness of breath or fatigue. Since the cancer has not spread in stage 0, outer lying symptoms such as weight loss, pain and fatigue are not as likely to occur.
