- Cancer has spread to any of the following:
- Major blood vessels that lead to or from the heart.
- Nerve that controls the larynx (voice box).
- Sternum (chest bone) or backbone.
- Carina (where the trachea joins the bronchi).
Stage IV non-small cell lung cancer. The cancer has spread to the other lung, and/or to lymph nodes, fluid around the lungs or heart, and/or other places in the body, such as the brain, liver, adrenal glands, kidneys, or bones.
In stage IV, the tumor may be any size and cancer may have spread to lymph nodes. One or more of the following is true:
- There are one or more tumors in both lungs.
- Cancer is found in fluid around the lungs or the heart.
- Cancer has spread to other parts of the body, such as the brain, liver, adrenal glands, kidneys, or bone.
