T groups
TX: The main growth can’t be evaluated for reasons unknown.
T0: There is no proof a main growth (the melanoma is found elsewhere instead).
T1: Mesothelioma is in the pleura protecting stomach walls on one hand of stomach. It may or may not also change the pleura protecting the diaphragm (the slim respiration muscular below the lungs) or the mediastinum (the area between the lungs). It may also have distribute to the pleura protecting the bronchi.
T2: Mesothelioma is in the pleura protecting stomach walls on one hand of stomach. It is also in the pleura protecting the diaphragm, the mediastinum, and the bronchi. It also has expanded into at least one of the following:
1. The diaphragm
2. The bronchi itself
T3: The asbestos has expanded further but may still possibly be eliminated with surgery treatment. The growth is in the pleura protecting stomach walls on one hand of stomach, as well as the pleura protecting the bronchi, the diaphragm, and the mediastinum. It also has expanded into at least one of the following:
1. The lower part of stomach walls (called the endothoracic fascia)
2. The excess fat in the mediastinum
3. A individual position in the further levels of stomach wall
4. The top of the pericardium (outer protecting part of the heart)
T4: The asbestos has expanded too far to be eliminated completely with surgery treatment. The growth has expanded into the pleura protecting stomach walls on one hand of stomach, as well as the pleura protecting the bronchi, diaphragm, and mediastinum on the same part. It also has expanded into at least one of the following:
1. More than one position in the further levels of stomach walls, such as the muscular or ribs
2. Through the diaphragm and into the peritoneum
3. Any body system organ in the mediastinum (esophagus, trachea, thymus, blood veins vessels)
4. The spine
5. Across to the pleura on lack of of the chest
6. Through the center protecting (pericardium) or into the center itself
