Mesothelioma is a rare form of cancer that occurs in the thin tissue that lines most of the internal organs (mesothelium). The doctor divides mesothelioma into several types based on which part of this cancer occurs.
- Pleural malignant mesothelioma, which occurs in the tissue lining around the lungs and is the most common type.
- Peritoneal mesothelioma, occurring in tissues that line the stomach.
- Pericardial mesothelioma, occurring in the tissue lining around the heart.
- Mesothelioma of the tunica vaginalis, occurs in the lining around the testicles
The symptoms of Mesothelioma
Signs and the symptoms of mesothelioma varies based on where the cancer occurs.
Pleural mesothelioma, signs and symptoms include:
• Shortness of breath
• Pain when breathing
• Pain when coughing
• Pain in the lower rib
• an unusual lump in the chest under the skin layer
• Lost weight suddenly
• Dry cough
Peritoneal mesothelioma, signs and symptoms include:
• Pain in abdomen
• Swelling in the abdomen
• Changes in bowel movements, such as more frequent diarrhea or constipation
• Lump in the tissues in the abdominal area
• Lost weight suddenly
Other forms of mesothelioma
Signs and the symptoms pericardial mesothelioma and tunica vaginalis are unclear. On health , there is no complete information about this. Pericardial mesothelioma have signs and symptoms that may include difficulty breathing or chest pain. While mesothelioma of the tunica vaginalis can be detected first by the enlargement of the testicles.
The Causes of Mesothelioma
In general, cancer occurs when cell DNA mutation. This mutation makes the cells continued to grow and flourish while others have normal cell cycles of life and death. Accumulation of cancer cells can form a malignant tumor.
It is unclear what causes the initial genetic mutations that lead to mesothelioma although scientists identify factors that may increase the risk. Cancer may result from a combination of several factors, such as heredity, environment, health condition and lifestyle.
Benign pleural mesothelioma
Benign tumors that form in the chest sometimes called benign mesothelioma. But the term is misleading. Benign mesothelioma is not started on the same cell where the cancer is formed. And in some cases kacil, benign mesothelioma can be very aggressive. For this reason, some doctors now prefer to call this tumor as a solitary fibrous tumor.
Solitary fibrous tumors usually do not cause signs and the symptoms. It is unclear what caused the solitary fibrous tumor, but tumors are associated with asbestos contamination pollutants. Treatment for solitary fibrous tumors usually includes surgery procedures.
