Mesothelioma Stage 1
Stage 1 of Malignant Mesothelioma
Mesothelioma involves either the right or left pleura lining the chest wall or diaphragm The malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage I Mesothelioma. Tumor involves the outermost layer of pleura (parietal pleura), but does not involve the pleura covering the lung (visceral pleura).
Mesothelioma Stage 2
Stage 2 of Malignant Mesothelioma
Cancer is found in the lining of the chest wall and the lymph nodes on the same side of the chest. Cancer may also be found in the lining of the lung, the lining of the diaphragm, or the lining of the sac that covers the heart on the same side of the chest.In the second stage, the two layers of the pleura are already affected by Mesothelioma. In this stage, only one side of the body is affected. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain.
Mesothelioma Stage 3
Stage 3 of Malignant Mesothelioma
The cancer has spread to any of the following areas:
- The chest wall.
- The mediastinum.
- The heart.
- Beyond the diaphragm.
- The peritoneum.
The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn't respond well to medication, the cancer may advance to the fourth stage.
Mesothelioma Stage 4
Stage 4 of Malignant Mesothelioma
The cancer has spread to distant organs or tissues. In the final stage, stage IV Mesothelioma, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. Tumor involves multiple areas of the chest wall, extends across the diaphragm or through the pericardium. In most cases, a patient who has reached stage IV Mesothelioma only has four to twenty-four months to live. Any distant metastases are included in this stage.
