Asbestos is a silent killer that has destroyed thousands of lives. For decades, millions of unsuspecting Americans were exposed to toxic levels of asbestos on their jobs, in their homes, at school, and numerous other places. The following video details the dangers of asbestos and the options available to victims of asbestos poisoning.
Individuals who incur significant asbestos exposure are at risk of developing asbestosis, lung cancer, mesothelioma (a fatal cancer that attacks the lining of the chest cavity and internal organs), and other serious illnesses.
In fact, the only proven cause of mesothelioma is asbestos. Individuals who worked in shipyards, including Navy facilities, are among those who are most frequently stricken with mesothelioma. The disease begins when the tiny fibers of asbestos are let loose in the air, where they are inhaled and become lodged in the lungs. There is no cure for mesothelioma.
All asbestos-related diseases can wreak havoc in the lives of individuals and their families, resulting in the loss of jobs, health, and often lives. If asbestos exposure or one of its related diseases has affected your life, your greatest resource is information.
Please take a moment to watch this video and learn all that you can about the silent epidemic of asbestos exposure and the ravages of mesothelioma and other asbestos-induced diseases. The more that you know about asbestos, the better prepared you will be to fight for your rights and those of your loved ones.

MESOTHELIOMA STAGES
Treatment options are often determined by the stage of mesothelioma a patient is in. There are three staging systems currently in use for pleural mesothelioma and each one measures somewhat different variables; peritoneal mesothelioma is not staged.
Staging is the term used to describe the extent of a patient's cancer, based on the primary tumor and its spread in the body. It can help the medical team plan treatment, estimate prognosis and identify clinical trials for which the patient may be eligible.
Staging is based on a knowledge of how the cancer develops, from the primary tumor, to the invasion of nearby organs and tissues, to distant spread or metastasis. Staging systems have evolved over time, and they continue to change as scientists learn more about cancer. Some staging systems cover many different types of cancer, while others focus on more specific cancers. The TNM (primary tumor, regional lymph nodes, distant metastasis) is the most common staging system for mesothelioma.
Some elements common to most staging systems are:
* Location of the primary tumor.
* Size and number of the tumors.
* Lymph node involvement.
* Cell type and tumor grade.
* Metastasis.
Many cancer registries, such as the National Cancer Institute's Surveillance, Epidemiology, and End Results Program (SEER) use summary staging, a system used for all types of cancer. Summary staging groups cancer into five main categories:
* In situ - cancer that is present only in the layer of cells in which it began.
* Localized - cancer that is limited to the organ in which it began with no evidence of spread.
* Regional - cancer that has spread from the primary site to nearby lymph nodes or organs.
* Distant - cancer that has spread from the primary site to distant lymph nodes or organs.
* Unknown - cases where not enough information exists to indicate stage.
Several types of testing may be used to help doctors determine stage, and to formulate a treatment plan.
* Physical examinations. The doctor examines the body by looking, feeling and listening to anything out of the ordinary.
* Imaging techniques. Procedures such as x-rays, CT scans, MRIs and PET scans may show the location, size of the tumor and whether the cancer has spread.
* Laboratory tests. Studies of blood, urine, fluid and tissue can provide information about the cancer. Tumor markers, sometime elevated when cancer is present, may provide information.
* Pathology reports. Results of the examination of tissue samples can include information about the size of the tumor(s), extension into adjacent structures, type of cells and grade of the tumor. Results of the examination of cells in fluid, such as that from a mesothelioma-related pleural effusion, may also provide information.
* Surgical reports. Observations about the size and appearance of the tumor(s), lymph nodes and nearby organs.
Staging information should be provided to the patient by his doctor so that potential treatment plans can be discussed. Stage of the mesothelioma, as well as consideration of other factors such as age, health status and the patient's wishes may dictate different treatment options.
The oldest staging system and the one most often used is the Butchart System which is based mainly on the extent of primary tumor mass and divides mesotheliomas into four stages. The more recent TNM system considers variables of tumor in mass and spread, lymph node involvement, and metastasis. The Brigham System is the latest system and stages mesothelioma according to resectability (the ability to surgically remove) and lymph node involvement.
Butchart System – extent of primary tumor mass
* Stage I: Mesothelioma is present in the right or left pleura and may also involve the diaphragm on the same side.
* Stage II: Mesothelioma invades the chest wall or involves the esophagus, heart, or pleura on both sides. Lymph nodes in the chest may also be involved.
* Stage III: Mesothelioma has penetrated through the diaphragm into the lining of the abdominal cavity or peritoneum. Lymph nodes beyond those in the chest may also be involved.
* Stage IV: There is evidence of metastasis or spread through the bloodstream to other organs.
TNM System -- variables of T (tumor), N (lymph nodes), M (metastasis)
* Stage I: Mesothelioma involves right or left pleura and may also have spread to the lung, pericardium, or diaphragm on the same side. Lymph nodes are not involved.
* Stage II: Mesothelioma has spread from the pleura on one side to nearby lymph nodes next to the lung on the same side. It may also have spread into the lung, pericardium, or diaphragm on the same side.
* Stage III: Mesothelioma is now in the chest wall, muscle, ribs, heart, esophagus, or other organs in the chest on the same side with or without spread to lymph nodes on the same side as the primary tumor.
* Stage IV: Mesothelioma has spread into the lymph nodes in the chest on the side opposite the primary tumor, or extends to the pleura or lung on the opposite side, or directly extends into organs in the abdominal cavity or neck. Any distant metastases is included in this stage.
Brigham System: (variables of tumor resectability and nodal status)
* Stage I: Resectable mesothelioma and no lymph node involvement
* Stage II: Resectable mesothelioma but with lymph node involvement
* Stage III: Unresectable mesothelioma extending into chest wall, heart, or through diaphragm, peritoneum; with or without extrathoracic lymph node involvement
* Stage IV: Distant metastatic disease

Pericardial Mesothelioma
Malignant pericardial mesothelioma is a type of cancer that originates in the mesothelium, a thin wall of cells that surround the body's organs and internal body structures. Pericardial mesothelioma originates in the lining of the heart. Other locales of the disease are malignant pleural mesothelioma, which occurs in the lining of the lungs and malignant peritoneal mesothelioma, which occurs in the abdomen wall. Pericardial mesothelioma is the rarest of these malignancies and accounts for only an estimated 10 percent of all mesothelioma incidences annually.
What Causes Pericardial Mesothelioma?
Pericardial mesothelioma is known only to be caused by exposure to asbestos, a naturally occurring but toxic mineral that was used in industrial capacities. While the precise route by which microscopic asbestos fibers reaches the pericardial lining is not known, physicians surmise that inhaled asbestos fibers are absorbed into the bloodstream and become entangled in the heart's lining as the blood processes through the heart. Mesothelioma occurring in other parts of the body, such as in the pleura or peritoneum, can also metastasize to the pericardial lining.
How is Pericardial Mesothelioma Treated?
Prognoses are poor in cases of pericardial mesothelioma, just as nearly all mesothelioma cases are. However, several treatment options exist to help patients manage the disease and maintain comfort. Chemotherapy and radiation therapy are the most likely treatment options for patients of this disease. Surgery is typically not an option because of the local of the disease and the risk of grave damage to the tumor area.
How is Pericardial Mesothelioma Diagnosed?
Physicians will often suspect pericardial mesothelioma if the patient has trouble breathing, shortness of breath, or chest pain. A comprehensive diagnostic and biopsy process will be undergone through use of multiple body imaging scans.
What a Patient's Options?
Patients of pericardial mesothelioma may be eligible for financial compensation if they were wrongly exposed to asbestos.

Peritoneal Mesothelioma
Malignant peritoneal mesothelioma is a rare type of cancer that occurs in the thin cell walls which surround the abdominal cavity, known as the peritoneum. Other types of mesothelioma include malignant pleural mesothelioma, occurring in the cell wall surrounding the lungs, and malignant pericardial mesothelioma, which occurs in the pericardial lining of the hearth. Peritoneal mesothelioma is the second rarest form of the disease and accounts for approximately 20% of all mesothelioma cases each year.
What Causes Peritoneal Mesothelioma?
Peritoneal mesothelioma is known only to be caused by exposure to asbestos, a microscopic natural fiber that was used heavily in industry. Asbestos is said to reach the abdominal wall by one of two methods. The first is through ingested asbestos fibers which are processed through digestion and become lodged in peritoneum. These other method is through the lungs and lymph nodes, by inhaled asbestos fibers. Mesothelioma of the pleura is also known to metastasize directly into the abdominal cavity if its spread is not slowed.
How is Peritoneal Mesothelioma Treated?
Prognosis of mesothelioma patients is poor, and peritoneal mesothelioma patients are no exception. Most peritoneal treatment regimens for patients include palliative methods such as chemotherapy and radiation therapy. However, if the disease is diagnosed in its earlier stages, patients may be eligible for surgical resection of the disease, which could potentially add years to initial prognoses.
How is Peritoneal Mesothelioma Diagnosed?
Physicians may suspect peritoneal mesothelioma if the patient complains of stomach, chest, or abdominal pain. Suspicious hernias may actually be a pleural effusion caused by peritoneal tumor growth. Misdiagnosis is common and patients will likely undergo multiple imaging scans and a diagnostic biopsy before an official diagnosis is made.
What are a patient's options?
Patients of peritoneal mesothelioma may be eligible for financial compensation if they exposed to asbestos. Industrial exposures were common and those exposed have collected compensation to finance high treatment costs.

Malignant Mesothelioma
Malignant Mesothelioma is a rare form of cancer that affects the thin cell wall lining of the body's internal organs and structures. This lining is known as the mesothelium. Malignant mesothelioma has three known varieties. They are malignant pleural mesothelioma, malignant pericardial mesothelioma, and malignant peritoneal mesothelioma. Pleural mesothelioma occurs in the pleura, the lung's lining. Peritoneal mesothelioma occurs in the peritoneum, the abdominal cavity wall. And pericardial mesothelioma occurs in the lining of the hearth, known as the pericardium.
What Causes Malignant Mesothelioma?
Mesothelioma is known only to be caused by asbestos exposure. Asbestos is a nature, yet toxic mineral that was used commonly in heavy industry. Microscopic asbestos fibers enter the body through the lung or ingestion. Once inside, the durable fibers are unable to be broken down or expelled by the body, causing a harmful inflammation and scarring of the mesothelium. This scarring lays the groundwork mesothelioma and other respiratory conditions, such as asbestosis.
How is Malignant Mesothelioma Treated?
Malignant mesothelioma prognoses are poor, as often the disease will be diagnosed in its later stages after symptoms have appeared. However, there are several treatment options for the management of the cancer. Among these are chemotherapy, radiation therapy, and surgical resection. Chemotherapeutic and radiation therapy methods are more likely but surgery is often an option for those whose disease is diagnosed early enough.
How is Malignant Mesothelioma diagnosed?
Malignant Mesothelioma will typically be suspected if the patient complains of chest pain, difficulty breathing, shortness of breath, chronic cough, or difficulty swallowing. While any of these could indicate mesothelioma, they are also associated with many other respiratory conditions so further diagnostic procedures are typically warranted. These may include imaging scans, such as computer topography or magnetic resonance imaging. A diagnostic biopsy is also required for cancer specialist to examine the behavior of these cells before a diagnosis is determined.
What options of patients of Malignant Mesothelioma have?
Patients of malignant mesothelioma or any other asbestos related health complications may be eligible for compensation if they were wrongfully exposed.
