What is Mesothelioma?

What is Mesothelioma?
Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart,[1] the pericardium (a sac that surrounds the heart) or tunica vaginalis.
Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways. Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma.[2] Unlike lung cancer, there is no association between mesothelioma and smoking.[3] Compensation via asbestos funds or lawsuits is an important issue in mesothelioma (see asbestos and the law).
The symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and general symptoms such as weight loss. The diagnosis may be suspected with chest X-ray and CT scan, and is confirmed with a biopsy (tissue sample) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to take biopsies. It allows the introduction of substances such as talc to obliterate the pleural space (called pleurodesis), which prevents more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.

Mesothelioma overview

Mesothelioma overview Mesothelioma is a dreaded cancer that is nearly always caused by just one factor: exposure to asbestos. Causes of Mesothelioma Before the grave dangers of asbestos were known, and even for years after the dangers were known, asbestos was used in literally thousands of products that humans and animals encounter every day - particularly in building components such as ceiling and floor tiles, walls, bricks and stucco, and in automotive parts such as brakes and clutches. People who worked in the asbestos industry or in fields in which asbestos is used as a component of a product are most at risk for mesothelioma. Many individuals who have mesothelioma labored for years or even decades in jobs that required frequent contact with asbestos. When this mineral is mined, processed, woven, sprayed or otherwise manipulated, its microscopic fibers can be released into the air, where they may be inhaled, initiating the development of mesothelioma.

Diagnosis of Malignant Mesothelioma:

Diagnosis of Malignant Mesothelioma: If there is a reason to suspect you may have mesothelioma, your doctor will use one or more methods to find out if the disease is present. The first step in diagnosing mesothelioma is recognizing your symptoms. Signs and Symptoms of Mesothelioma Early symptoms of mesotheliomas are not specific to the disease. People often ignore them or mistake them for common, minor ailments. Most people with mesothelioma have symptoms for only 2 to 3 months before they are diagnosed. About one-fourth of people have symptoms for at least 6 months before they are diagnosed. Over half of patients with pleural mesothelioma have pain in the lower back or at the side of the chest. Many report shortness of breath. A smaller percentage have trouble swallowing, cough, fever, sweating, fatigue, and weight loss. Other symptoms include hoarseness, coughing up blood, swelling of the face and arms, muscle weakness, and sensory loss. Symptoms of peritoneal mesothelioma include a...
