Mesothelioma Cancer
Mesothelioma is a type of cancer that develops in the linings of different organs. This includes the pleura (lung), peritoneum, and the pericardium. In rare instances, it may form in the tunica vaginalis (testicular).
Asbestos is the primary risk factor for mesothelioma. It could also be caused by genetic mutation or radiation exposure.
Pleural Mesothelioma
Mesothelioma mostly affects the lung lining (pleural mesothelioma) or the lining of the abdomen (peritoneal mesothelioma). It may also affect the membrane surrounding the testicles and the heart. Typically, the signs of mesothelioma come and go over time and may not show up until in the latter stages.
Mesothelioma can be triggered by asbestos exposure. People develop the disease when asbestos fibers stray into their bodies via breathing, swallowing or contact with their skin. These fibers adhere to the organ linings and cause tumors to form slowly. This can take 10 to 50 years, which is the reason it is so difficult for doctors to recognize mesothelioma in its early stages.
Most common pleural msothelioma symptoms and signs include chest pain and trouble breathing. These symptoms are similar to those of an illness such as a cold or flu, and they may not show up until late in the course of cancer's growth. A biopsy as well as review of the patient's history of exposure can aid a doctor in determining if the symptoms are linked to mesothelioma.
A doctor can test a person's blood for certain proteins produced when mesothelioma tumor cells multiply. They can also request an MRI or CT scan to determine the signs of mesothelioma. In addition, a doctor can perform a thoracoscopy to examine the chest cavity to detect symptoms of asbestos-related disease.
The tissue lining the chest or lungs is typically affected by mesothelioma of the pleural region. It can also be found in the linings of the abdomen or the heart. This type of mesothelioma is most common in people who are exposed to asbestos while at work. Family members of asbestos workers could be more prone to developing the disease if they are exposed to home fibers from their clothing or skin.
There are two principal types of mesothelioma namely epithelioid and sarcomatoid. 60 percent to 70 percent of mesothelioma patients suffer from epithelioid tumors, which are more likely to be successfully treated. The remaining 10 percent to 15% are sarcomatoid, which have a poorer prognosis. A small proportion of cases are classified as biphasic, or mixed, that have epithelioid as well as mesothelioma cells that are sarcomatoid.
Peritoneal Mesothelioma
Peritoneal mesothelioma occurs when asbestos fibers are breathed in or swallowed and end up in the lining of the abdomen known as the peritoneum. Asbestos fibers which settle in the peritoneum cause irritation to the mesothelial cell and cause them develop abnormally. In time, mesothelioma increases and spreads to various organs. Mesothelioma symptoms are usually not specific and difficult to recognize. Peritoneal mesothelioma can cause abdominal discomfort and nausea, as well as fever and weight loss. People with mesothelioma should discuss their history of exposure with a physician to ensure they receive the right treatment.
All types of mesothelioma are at risk when exposed to asbestos. Since mesothelioma has an extended latency time, it can take years after exposure for symptoms to show up.
Asbestos can also affect the lungs and the digestive tract. People who experience these symptoms should consult a mesothelioma specialist.
When mesothelioma has been diagnosed and treated by doctors, the underlying cancer as well as the symptoms. Patients can expect to undergo chemotherapy, surgery and palliative care.
A doctor will look for mesothelioma using the procedure of a biopsy. This is an invasive procedure which involves inserting a needle inside the body of a patient in order to remove a small piece of tissue. The tissue sample will be examined in a lab for the presence of malignant cells.
If mesothelioma has been identified the surgeon will be able to remove both the tumor as well as any lymph nodes in the vicinity. They will also drain fluid that has accumulated in the abdomen, which is known as ascites. This is done using the procedure known as abdominal paracentesis or ascitic tap.
Doctors can use intraperitoneal chemotherapy to kill mesothelioma direct in the stomach. This is typically done in conjunction with a surgical procedure referred to as cytoreductive surgery using HIPEC or the Sugarbaker procedure.
Mesothelioma patients can bring a lawsuit against companies that manufactured and sold asbestos products. A successful lawsuit may help victims and their families members get the money they deserve. Request your free Mesothelioma Guide today to learn more about filing a claim.
Thoracic Mesothelioma
Mesothelioma is a cancer that affects the lung's lining (pleura). It also can occur in the lining of the abdomen and chest cavity (peritoneum) as well as around the testicles and heart (pericardium). Mesothelioma is a cancerous tumor that arises from mesothelium cells. Exposure to asbestos increases the chance of mesothelioma developing. It usually takes 20 to 60 years for mesothelioma develop following exposure. People who have been exposed to asbestos or in close proximity to it, like blue collar workers and veterans, are at a greater risk.
The exact causes of mesothelioma are not known. However, scientists believe that asbestos inhaled, or swallowed it causes irritation and changes in the genetics of the mesothelium. These changes could lead to cancerous tumors in the future. The most frequent form of mesothelioma is pleural mesothelioma.
People diagnosed with pleural mesothelioma have an estimated life expectancy of one to four years following diagnosis. The tumors spread and grow quickly, reducing your chances of surviving.
Most cases of pleural mesothelioma are related to long-term, high-level exposure to asbestos. However, mesothelioma has also been caused by short-term, low-level exposure to asbestos.
The symptoms include chest pain, difficulty breathing, weight loss, coughing and abdominal swelling. Pleural mesothelioma is also associated with fluid buildup between the lungs, chest wall and abdomen (pleural effusion).
The best way to diagnose mesothelioma accurately is to take tissue samples during the procedure of a biopsy. This can be accomplished with a CT-guided semi-invasive procedure or open surgery. Doctors can also use MRI to determine if mesothelium has migrated beyond the lung and mesothelioma asbestos cancer into the chest wall or diaphragm.
Avoiding asbestos is the most effective method to avoid mesothelioma. If you think you may have been exposed to asbestos, speak to your GP. Anyone who has been employed in locations where asbestos was used should have their occupational history documented, even if they do not remember being exposed. Countries that continue to mine and manufacture asbestos must be forced by international pressure to stop production. People living in close proximity to demolition sites or mines where asbestos was produced should wear protective equipment.
Vascular Mesothelioma
Mesothelioma is an asbestos-related cancer. It is a problem for organ linings such as the lungs and abdomen. Asbestos fibers can cause this condition. Asbestos is composed of fibres that are pliable and fireproof. Builders use them to make products and buildings more durable. Asbestos is still present in certain countries, but has been banned in others.
Asbestos can cause mesothelioma getting into your lungs and abdomen through your mouth or nose. Asbestos particles may then go into the bloodstream and be transported to other parts of your body. Mesothelioma can take years to develop following exposure to asbestos.
There are three major types of mesothelioma. Pleural mesothelioma targets the lungs. Peritoneal mesothelioma affects the abdomen's lining. Pericardial mesothelioma is the rarest kind and targets the lining of the heart.
Diagnosed with chest X-ray or computed Tomography (CT) scan, or magnetic resonance imaging. Treatment options differ based on the kind of cancer you are suffering from.
In general malignant mesothelioma is known to grow more quickly than benign tumours. It also has a longer period of inactivity-up to 40 years in certain cases, and is more likely to develop following long-term exposure to asbestos.
The precise distinction between mesothelioma versus vascular sarcoma of the serous membrane is vital for medical reasons, as only mesothelioma with malignant characteristics is recognized as an asbestos-related neoplasm for compensation purposes. However, no legitimate case of vascular sarcoma of the pleura has been attributable to asbestos exposure to date.
A small number of patients with diffuse pleural epithelioid haemangioendotheliomas and lymphovascular sarcomas of the pleura have been reported to have claimed previous exposure to asbestos. These tumors are similar malignant mesothelioma, both clinically and morphologically. Studies of immunohistochemistry suggest that these tumours are unlikely to have an asbestos-related etiology because they do not show the endothelial marker CD31 or CD34. Further, the presence of pleural fibrous tissue and ferruginous bodies that are characteristic of asbestos exposure were not detected.
