The internal organs of the human body are encased in a protective sac called the mesothelium. Examples of mesothelilial membranes are the peritoneum (abdominal organs),), pleura (lungs) and pericardial (heart.
Under certain conditions, divide the cells of the protective membrane and the uncontrolled development of cancer. This disease is known as mesothelioma, a rare form of cancer that is caused by prolonged exposure to asbestos dust.
The disease is found to come underthose who work in shipyards, asbestos mines and factories, industries that produce asbestos products, and the heating and construction companies. Approximately 3,000 cases occur each year in the U.S., and most patients are aged between 50-70 years. Statistics show that commonly affects men and whites among them more than African-Americans.
Initially studied in the late 1700s and deeply involved, were conducted only in the 1960s. Tumors of the Mesothelioma can be benign ormalignant. The malignant mesothelioma are divided into three categories:
• epithelioid a share of 50-70% of mesothelioma.
• Sarcomatoid a share of 7-20%.
• Mixed-or bi-phasic share of 20-35%.
When asbestos fibers are inhaled into the lungs they travel through large air passages to the smaller agencies to reach them and the pleura. In the thoracic cavity, they damage: the mesothelial cells leads to cancer, lung tissue causing lung cancer, and theDevelopment of scar tissue in the lungs known as asbestosis. When asbestos fibers are swallowed, they reach into the abdominal cavity and cause peritoneal mesothelioma.
Research shows that the disease is only 20-50 years are exposed to asbestos dust. The symptoms are not specific for the disease, but to develop a patient to:
• shortness of breath.
• Chest pain accompanied by tightness believed to be caused by the accumulation of fluid in thePleura.
• lower back pain.
• swelling of the face and arms.
• Sensory loss.
• Muscle weakness.
• nausea.
• vomiting.
• Weight loss that is unexplained.
• Persistent dry cough.
• sore throat.
• Anemia.
• Fever.
• Constipation.
• problems with blood clotting.
Since the above are common minor ailments, patients often ignore the symptoms. It is advisable to consult a doctor if any of the aboveSymptoms persist or if you think you have been knowingly or unknowingly exposed to asbestos.
A doctor will:
• Take a detailed medical history and try to determine the symptoms and risk factors.
• Perform a thorough physical examination and testing for signs of:
o pleural effusion, fluid accumulated in the chest cavity.
O fluid in the abdominal cavity.
o pericardial effusion, fluid in the lining of the heart.
• Take a chest x-ray check andthickening of the pleura, calcification, and reduced lung fissures.
• Ask for a CT scan, the location, determine the size and the extent of the problem when everyone is a suspect.
• site testing of tissue samples and pleural fluids.
Other risk factors include cigarette or cigar smoke, radiation exposure, exposure to a compound zeolite caused by asbestos exposure or infection, which is by SV40, a simian virus causes similar.
Those who work on a riskyEnvironment should wear protective clothing, tested the area regularly exposed to asbestos particles and to ensure that regular medical examinations and reports to the physician all the complaints, challenges remain.
The knowledge of the disease and their problems helps.
