When diagnosed with lung cancer, a stage of the lung
disease is identified to describe the severity and indicate the extent of
its progression. This staging of lung cancer is used by healthcare
professionals to determine the choice of treatment that will best rid the
body of the lung cancer. The survival rate is usually calculated in 5-year periods and the stages will be divided according to the type of lung
cancer in the body.
Non-small Cell Lung Cancer
Stage 0 Lung Cancer
The lung cancer is localized; it is found only in a local area and only in
the first few layers of cells. The lung cancer has not penetrated the
surface lining of the lungs. In this case, surgery can be done to remove
infected tissue and prevent the spread of tumor cells.
Five-Year Survival Rate = 70 - 80%
Stage I Lung Cancer
The lung cancer is confined to the lungs and surrounded by normal tissue.
Five-Year Survival Rate = 50%
Stage II Lung Cancer
The lung cancer has spread to nearby lymph nodes.
Five-Year Survival Rate = 30%
Stage III Lung Cancer
The lung cancer has spread to the chest wall, diaphragm, or other nearby
organs or blood vessels. The lung cancer may have spread to lymph nodes in
the mediastinum or the other side of the chest or neck.
Five-Year Survival Rate = 5 - 15%
Stage IV Lung Cancer
The lung cancer has spread to more distant sites in the body. After this
stage, almost nothing can be done to treat the patient. The patient is
then called terminally ill.
Five-Year Survival Rate = Less than 2%
Small Cell Lung Cancer
Limited Stage Lung Cancer
The lung cancer is confined to one of the lungs and
nearby lymph nodes.
Five-Year Survival Rate = 15 - 30%
Extended Stage Lung Cancer
The lung cancer has spread to other lung tissues or other areas of the
body.
Five-Year Survival Rate = 0 - 2%
