Definition
Mesothelioma is a rare type of cancer that occurs to the thintissue that lines most of the internal organs (mesothelium) . Doctors divide mesothelioma into several types based on which part of this cancer occurs . Among other things ,
• Pleural malignant mesothelioma , utilize in the tissue liningaround the lungs and is the most common type.
• Peritoneal mesothelioma , occursin tissues that line the stomach.
• Pericardial mesothelioma , occurs in the tissuelining around the heart.
• Mesothelioma of the tunica vaginalis , occurs in the liningaround the testicles .
Symptoms
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 the lower rib
• Unusual lumps on the chest under the skin layer
• Lost weight suddenly
• Dry cough
Peritoneal mesothelioma, signs and symptoms include:
• Pain in the abdominal area
• Swelling in the abdomen area
• Changes in bowel movements, such as being more likely to experience diarrhea or constipation
• A lump in the tissue in the abdominal area
• Lost weight suddenly
Other forms of mesothelioma
Signs and symptoms of pericardial mesothelioma and tunica vaginalis are unclear. There is no complete information on this subject. Pericardial mesothelioma have signs and symptoms that may include difficulty breathing or chest pain. While mesothelioma of the tunica vaginalis was first detected by the enlargement of the testicles.
Causes & Risk Factors
Causes
In general, cancer occurs when cells mutate DNA. These mutations make the cells continued to grow and thrive while others have normal cell cycles of life and death. The accumulation of these cancer cells can form malignant tumors.
It is unclear what causes the initial genetic mutations that lead to mesothelioma although scientists identify factors that may increase the risk. Cancer may occur due to a combination of several factors, such as heredity, environment, health condition and lifestyle.
Pleural mesothelioma benign
Benign tumor that forms in the chest sometimes called benign (benign) mesothelioma. But the term is misleading. Benign mesothelioma is not started in the same cell where the cancer is formed. And in some cases kacil, benign mesothelioma can be very aggressive. For this reason, today some doctors prefer to call this tumor as a solitary fibrous tumor.
Solitary fibrous tumors are usually not cause signs and symptoms. It is unclear what caused the solitary fibrous tumor, but the tumor is associated with asbestos contamination pollutants. Treatment for solitary fibrous tumors usually includes surgery procedures.
Risk factors
- Exposure to asbestos pollutants (primary risk factor)
Asbestos is a mineral that is found in the neighborhood. Asbestos fiber is strong and resistant to heat makes it very useful to be applied to a variety of needs. People who work in environments polluted many asbestos fibers have a greater risk of developing mesothelioma.
When asbestos split - such as the manufacturing process - asbestos dust is formed. If dust is inhaled or swallowed asbestos fibers will then settles in the lungs or in the stomach and can cause irritation that causes mesothelioma.
Some people who for years exposed to asbestos pollution can not be experienced mesothelioma, while others are the opposite. This indicates that other factors may be relevant, namely heredity if you have a family history of cancer in some people is a condition that increases the risk.
Risk factors that may
Risk factors that may increase the risk of mesothelioma include:
• Exposure to asbestos fiber dust pollution
• Living with someone who works in an environment with asbestos (asbestos fibers attached to their clothing or skin)
• Smoking
• SV40 virus found in many primates
• X-ray radiation
• Family history of mesothelioma
Prevention
Beware if you are working in an environment with asbestos
Many people who experienced mesothelioma exposed to asbestos fibers while working at places such as:
• Mine
• Factory worker
• Manufacturing of electronic components
• Making rail
• Shipbuilding
• Construction workers
• Mechanics
For prevention it can be done by:
• Follow standard safety regulations
• Do not use objects that contain asbestos in your neighborhood
