Diffuse Malignant Mesothelioma

computed tomographyDiffuse Mesothelioma is a malignant tumor more common than localized but have little impact. It is estimated that around 15-18 cases per million occur annually, most often in males and in the sixth decade of life. It has been described as etiologic agent of this cancer to asbestos exposure that has a long latency period (more than 20 years), so it is expected that the incidence does not decrease for several years in which case periods are detected in the there was no right to prevent exposure to asbestos. Of the various types of existing asbestos fibers, which has been linked directly to this type of cancer is crocidolite. Sometimes, however, is impossible to prove exposure to mineral in people suffering from diffuse mesothelioma. There are also other possible etiologic factors among which exposure to radiation.

From the standpoint of pathological form of mesothelioma from mesothelial or subserosal multipotential cells and can lead to a variety epithelial, sarcomatous, or mixed between the two. The epithelial variety has large similarities with pleural metastatic adenocarcinoma, so that in practice it is very difficult to distinguish a tumor from another. The immunohistochemical studies (antibodies against cytokines high and low molecular weight, embryonal carcinoma antigen) and electron microscopy are essential to establish this distinction.

Pleural mesothelioma takes multiple nodular growth with a tendency to coalesce and invade the visceral pleura from of the wall which is the first seat. The lung is physically trapped by the tumor masses are introduced into the hilum of the lung, chest wall, diaphragm, mediastinum and contralateral hemithorax. A classification according to its extension.

The clinical manifestations are usually inconspicuous in the early stages of the disease. Chest pain is very intense and is present in the vast majority of occasions. Dyspnea is also very important as the tumor grows, it traps the lung and pleural effusion occurs. The patient’s general condition deteriorates intensively with significant constitutional symptoms and weight loss. Auscultation reveals a decrease or abolition of breath sounds and can be found on the chest wall mass and, more rarely, supraclavicular or cervical lymphadenopathy. Paraneoplastic manifestations can be found (autoimmune hemolytic anemia, hypoglycemia, antidiuretic hormone secretion) but are rare. (more…)

Mesothelioma types

Mesothelioma is a malignant form of cancer, known for its genesis in the mesothelium – the protective lining that covers most of the internal organs of the body.

The mesothelium is composed of cells as are all types of living tissue, and when the cells begin to grow at a rapid rate and abnormal and begin to affect the operation of nearby organs.

Over time, these malignant cells spread throughout the body, causing increasing deterioration of the function until the body stops working.

The three types of mesothelioma that there are

• Pleural – mesothelioma in the lining of the lungs
• Periotoneal – mesothelioma in abdominal cavity
• Pericardial – mesothelioma of the sac surrounding the heart.

The disease is divided into three types of malignant mesothelioma on the basis of their cellular structure:

• epithelioid mesothelioma (50% to 70% of all cases of malignant mesothelioma – the most common)
• sarcomatoid mesothelioma (10% to 15% of mesothelioma cases – the least common type)
• Mixed or biphasic mesothelioma (20% to 40% of cases of mesothelioma – a combination of both)

Although there are many forms of therapy, there is still no cure for mesothelioma.

Mesothelioma is associated with exposure to asbestos. If you have mesothelioma, please contact one of our attorneys for a confidential assessment of your case.

Types of Lung Cancer

There are several different types of lung cancer. This will give an overview of different types, and the important differences between them.

Secondary lung cancer is cancer that started elsewhere in the body and has spread into the lungs. Primary lung cancer refers to cancer that has begun in the lungs. There are two types of primary lung cancer: small cell lung cancer and non small cell lung cancer.

The small cell lung cancer is usually caused by smoking. This type of cancer gets its name from the small cancer cells that are mostly filled with the nucleus – the control center of the cell. Approximately one fifth of all diagnosed lung cancers are small cell lung cancers.

This type of cancer can spread very rapidly in the early stages, and doctors often suggest chemotherapy as a course of treatment rather than surgery. The Squamous cell carcinoma is a no small cell lung cancer. This is one of the most common types of lung cancer, and develops from cells that line the airways. It is often found near the center of the lung in the left or right bronchus.The Squamous cell carcinoma is often caused by smoking, but may have other causes. Adenocarcinoma is a no small cell lung cancer. This type of lung cancer develops from cells that produce mucus. It is often found in the outer regions of the lungs.

The large cell carcinoma is a no small cell lung cancer. This type of cancer gets its name because the cells look large and bent. The large cell carcinoma tends to grow very quickly. The non-small cell lung cancer means that undifferentiated cells in a biopsy are underdeveloped and are not clearly one of the three non-small cell cancers. The treatment is the same, regardless.

Mesothelioma is a rare type of lung cancer that affects the covering of the lung, known as the pleura. This type of cancer is often caused by exposure to asbestos, and is very different from other types of lung cancer.

Stages of Malignant Mesothelioma

Once malignant mesothelioma, will become more tests to determine if cancer cells have spread to other parts of the body. This procedure is known as staging. The doctor needs to know the stage where the cancer to plan treatment. For the classification of malignant mesothelioma following stages are used.

Localized malignant mesothelioma

* Stage I
Cancer is found in the lining of the chest cavity near the lung or heart, or diaphragm or lung.

Advanced malignant mesothelioma

* Stage II
The cancer has spread beyond the lining of the chest to lymph nodes in the area.

* Stage III
The cancer has spread to the chest wall, the center of the chest, heart, through the diaphragm, or abdominal lining, and in some cases lymph nodes.

* Stage IV
The cancer has spread to distant organs or tissues.

Recurrent malignant mesothelioma
Speaking of Recurrent disease means the cancer has come back (recurred) after it has been treated. May reappear in the lining of the chest or abdomen, or elsewhere in the body.

What is Malignant Mesothelioma?

Malignant mesothelioma, a rare form of cancer is a disease in which cells are cancerous (malignant) in the sac lining the chest (the pleura) or the lining of the abdomen (peritoneum). Most people with malignant mesothelioma have worked in places where they breathed asbestos breathing.

You should see a doctor if you have shortness of breath, pain in the chest or pain or swelling in the abdomen. If you have symptoms, your doctor may send you to do a chest or abdomen.

The doctor may look inside the chest cavity with a special instrument called a thoracoscope. To do this, make an opening through the chest wall and install the thoracoscope into the chest between two ribs. This test, called thoracoscopy, is usually performed in a hospital. Before the test, be given a local anesthetic (a drug that causes loss of feeling for a short period of time.) You may feel some pressure, but usually no pain.

Malignant Mesothelioma

malignant mesotheliomaStudies in the United States, malignant mesothelioma is the most common primary neoplasm of the pleura. But it remains rare in the general population, which are seven to thirteen new cases per million people exposed to factors in this cancer-like asbestos, and it is estimated that may occur one to two new cases per million person exposed to them.

Malignant mesothelioma
is characterized by producing nodules, masses, effusions and pleural thickening, unilateral, in which most often is accompanied by an invasion of fissures and at the same lung. A major problem with this neoplasm is the differential diagnosis with conditions such as fibrosis by asbestos, asbestos reactive hyperplasia, lung cancer, pleura and spread to others.

Radiology, topography and magnetic resonance imaging to determine the tumor, but a definitive diagnosis will be determined by pathology.
