The term mesothelioma defines a rare form of cancer which affects the mesothelium, a protective membrane covering the major part of the internal organs. The mesothelium is named differently depending on the organ it covers: peritoneum (lining the organs within the abdominal cavity), pleura (covering the lungs), the pericardium (lining and protect the heart), vaginal tunic (surrounding the male internal reproductive organs) or cervical tunica serosa (lining the internal reproductive organs in women).
Protect the bodies it covers, this membrane also produces a lubricating fluid, published between the two layers of the meshotelium. Mesothelioma occurs mainly in people working in toxic environments, with a high concentration of asbestos. When toxic this mineral fibers are ingested or inhaled, they become deposited in organs and cavities, leading to infections and inflammatory processes. Usually, they generate high cellular damage and overtime, they begin to divide out of control. As a result, the two layers of the mesothelium become thicker and the fluid between them begins to accumulation.
In most patients, it takes up to 50 years after exposure to asbestos to develop symptoms of mesothelioma. Considering the fact that, in the early stages, this form of cancer is asymptomatic, the prognosis for mesothelioma depends on how advanced the disease is diagnosed. Diagnosed in early stages. On the other hand, if mesothelioma is diagnosed when it has reached advanced stages, healing options are very limited and the prognosis is often compromised.
Pleural mesothelioma is the most common form of cancer, and it occurs usually through dry cough persisted, dysphagia (difficulty swallowing), dyphnea (shortness of breath), night sweats and fever, fatigue and persistent pain in the area of the chest. In this type of mesothelioma, respiratory function is the most affected.
Peritoneal Mesothelioma may be recognized by symptoms such as weight loss, unexplained, stress and anemia, fatigue, frequent episodes of diarrhea or constipation, abdominal pain, lumps and swelling, nausea and vomiting. Less frequent than this type of mesothelioma, cancer pericardium leads palpitations heart and pain in the chest, shortness of breath, fever and generalized fatigue. Testicular mesothelioma is extremely rare, the reduction of the number of known cases makes it more difficult to establish typical symptoms. The only common sign reported in the literature is the appearance of testicular lumps, which can be painful in some patients.
Diagnosis is generally based on the patient’s medical history, physical examination and – in the case of mesothelioma symptoms are present, additional tests may be needed – usually, x-rays, CT, MRI or PET scans. If the result of these tests is positive, and cancer is identified, the doctor may also order a biopsy, to determine if mesothelioma is benign or malignant.
With regard to the treatment, the most common alternatives are surgery, chemotherapy and radiation therapy. Surgery is used to remove affected tissue and relieve typical symptoms. Radiotherapy kills existing cancer cells and inhibits the growth of new, while chemotherapy uses drugs to target the cells responsible for the development of mesothelioma.
