Malignant Mesothelioma Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Malignant Mesothelioma
Cancer has spread to lymph nodes where the lung joins the bronchus, along the trachea and esophagus, between the lung and diaphragm, or below the trachea.
Cancer is found in one side of the chest in the lining of the chest wall, the lining of the chest cavity between the lungs, the lining that covers the diaphragm, and the lining that covers the lung. Cancer has spread into one or more of the following:
- Tissue between the ribs and the lining of the chest wall.
- Fat in the cavity between the lungs.
- Soft tissues of the chest wall.
- Sac that covers the heart.
Cancer may have spread to lymph nodes where the lung joins the bronchus, along the trachea and esophagus, between the lung and diaphragm, or below the trachea.
Stage IV (Advanced)
In stage IV, cancer cannot be removed by surgery and is found in one or both sides of the body. Cancer may have spread to lymph nodes anywhere in the chest or above the collarbone. Cancer has spread in one or more of the following ways:
- Through the diaphragm into the peritoneum (the thin layer of tissue that lines the abdomen and covers most of the organs in the abdomen).
- To the tissue lining the chest on the opposite side of the body as the tumor.
- To the chest wall and may be found in the rib.
- Into the organs in the center of the chest cavity.
- Into the spine.
- Into the sac around the heart or into the heart muscle.
- To distant parts of the body such as the brain, spine, thyroid, or prostate.
