Mesothelioma is a rare form of cancer that occurs in the thin tissue that lines most of the internal organs (mesothelium). Doctors divide mesothelioma into several types based on which part of these cancers occur.
Malignant pleural mesothelioma, which occurs in the lining tissue around the lung and is the most common type.
Peritoneal mesothelioma, occurring in tissues that line the stomach.
Pericardial mesothelioma, which occurs in the tissue lining around the heart.
Mesothelioma of the tunica vaginalis, occur in the lining around the testicles
Symptoms of Mesothelioma
Signs and symptoms of mesothelioma vary based on where the cancer occurs.
Pleural mesothelioma, signs and symptoms include:
• Shortness of breath
• Pain when breathing
• Pain when coughing
• Pain in lower ribs
• an unusual lump in the chest under the skin layer
• Losing weight suddenly
• Dry cough
Peritoneal mesothelioma, signs and symptoms include:
• Pain in the abdomen
• Swelling in the abdomen
• Changes in bowel movements, such as more frequent diarrhea or constipation
• Lump in the tissue in the abdominal area
• Losing weight suddenly
Other forms of mesothelioma
Signs and symptoms of pericardial mesothelioma and the tunica vaginalis are unclear. In health, there is no complete information about this. Pericardial mesothelioma have signs and symptoms may include difficulty breathing or chest pain. While mesothelioma of the tunica vaginalis can be detected first by enlargement of the testis.
Causes of Mesothelioma
In general, cancer occurs when cells of DNA mutations. This mutation makes the cells continued to grow and thrive while others have normal cell cycle of life and death. Accumulation of cancer cells can form malignant tumors.
It is unclear what caused the initial genetic mutations that cause mesothelioma even though the scientists identify the factors that may increase the risk. Cancer can 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 is sometimes called mesothelioma jinak.Tetapi this 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 solitary fibrous tumor.
Solitary fibrous tumors usually do not cause signs and symptoms. It is unclear what caused the solitary fibrous tumor, but tumors are associated with asbestos contamination of pollutants. Treatment for solitary fibrous tumors usually includes surgery procedures.
