Mesothelioma is a cancer that develops in the protective lining of internal organs. The most common cases are found in those of lungs, abdominal cavities, heart, and testis.
Mesothelioma is often referred to as asbestos mesothelioma, because most cases of mesothelioma are linked to exposure to asbestos dust and fibers. Often mesothelioma is caused by inhalation.
Asbestos was popularly used in building materials because of its sound absorption, tensile strength, fire resistance, and resistance of heat, electrical and chemical damage, and affordability. As a result that has lead to many class action lawsuits.
Signs and symptoms of mesothelioma include shortness of breath, chest pain, and unexplained weight loss. Preliminary diagnosis may result from chest X-ray and CT scan. Firm diagnosis requires effusion cytology or with a biopsy (removing a sample of the suspicious tissue) and microscopic examination.
Research of the type of cancer is still in an early stage. Treatment with chemotherapy, radiation therapy or surgery, still has poor results. Research about screening tests for the early detection of mesothelioma is ongoing.
