Malignant Mesothelioma - Types, Causes, Stages and Treatment Options

Malignant mesothelioma is an uncommon form of cancerous tumors originating in the body tissue known as the mesothelium. The mesothelium is a specialized layer of cells that line and protect many internal organs such as the chest and abdominal cavities.

Types of Malignant Mesothelioma

The first type of malignant mesothelioma is called Pleural Mesothelioma or mesothelioma of the pleura. It is the most common type of mesothelioma making up approximately 75% of all mesothelioma cases. The pleura is a thin serous membrane found between the lungs and the chest cavity that provides a lubricated surface preventing the lungs from chafing against the chest walls. It also serves as a protective layer.

The second most common type of mesothelioma is Peritoneal Mesothelioma, also known as mesothelioma of the peritoneum. The peritoneum is a thin serous membrane that encloses the organs of the abdomen. Peritoneal Mesothelioma is a rare form of malignant mesothelioma cancer. This disease accounts for approximately 10% to 20% of all mesothelioma cases. It tends to be a more invasive form of cancer; patients diagnosed with this disease have a shorter life expectancy than if they had attracted Pleural Mesothelioma.

The third and least common type of mesothelioma is pericardial mesothelioma also known as mesothelioma of the pericardium. It accounts for less than 10% of all mesothelioma cases. The pericardium (heart sac) is the serous membrane that surrounds and protects the heart.

There are about 2,200 new cases of malignant mesothelioma of the visceral pleura each year. Mesothelioma is difficult to diagnose and is rarely curable. The most common symptoms are dyspnea and chest wall pain.

Causes



Asbestos is the predominant cause of malignant mesothelioma of the visceral pleura. The period between the time of exposure to asbestos and the onset of symptoms is about 20 to 50 years. Because of this late onset, it occurs most commonly in the later years of life. It also occurs more often in men than in women.

Diagnosis

Doctors usually make an incision through the chest wall and insert an instrument called a thoracoscope between two ribs to view the area. Doctors will then do a biopsy to select a tissue sample that can be analyzed under a microscope.

Stages of Mesothelioma

Stage I: The cancer is found in the lining of the chest cavity near the lung and heart or in the diaphragm or the lung.

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

Stage III: Cancer has spread into the chest wall, center of the chest, heart, through the diaphragm, or abdominal lining, and in some cases into nearby lymph nodes.

Stage IV: Cancer has spread to distant organs or tissues.

Treatment



Radiation and radiotherapy are used in situations where the cancer is localized at the point of origin.

Chemotherapy is used in more advanced stages of malignant mesotheliomas.

Cytoreductive surgery plus hyperthermic (heated) chemotherapy improves the survival and quality of life for patients with peritoneal metastases (tumors involving the lining of the abdomen).

Surgery is the option used for Stage I malignant mesothelioma. For stages II to IV, treatment by surgery is still evolving.

Mesothelioma Cancer: Early Recognition of Symptoms is Key to Successful Treatment

Symptoms of mesothelioma take many years to become apparent. In other words it has a long latency period. This makes it difficult to diagnose and treat. The person may repeatedly visit the doctor with the symptoms but more often considered as respiratory infections. The non-specific symptoms make it hard for even experienced doctors to make a quick and conclusive diagnosis with mesothelioma patients. Even people exposed to asbestos start showing the manifestation late in their life. By the time, mesothelioma is diagnosed, it is already widespread. However, the awareness of mesothelioma has made people detect it in early stages.

Manifestation of mesothelioma largely depends upon the location size and nature of the tumor. Sign and symptoms also depend upon whether the tumor is benign or malignant. Benign type of mesothelioma usually does not manifest itself. On the other hand, malignant type of mesothelioma has severe symptoms. It is mostly due to the pressure exerted on surrounding soft tissues. The malignancy may invade surrounding tissues or may result in pericardial or pleural effusion. Invasion of the chest wall may lead to chest pain.

The early symptoms to watch out for are:

Hemoptysis or Blood in the sputum
A cough or a change in cough pattern
Dysphagia or Difficulty in swallowing
Hoarseness
Shortness of breath
Pain in the chest or abdomen
Significant Weight loss.

Among all types of mesothelioma, the pleural form is the most prevalent form. As a result the pleural symptoms are the most common manifestations of mesothelioma. When in early stages, the symptoms are more or less like pneumonia and hence often misdiagnosed. However these symptoms along with history of asbestos exposure should ring alarms for mesothelioma. Physicians should be well aware of it as usually they are the first to get in contact with the patient.

Pleural mesothelioma

Dyspnoea or shortness of breath along with chest pain is common manifestation of pleural mesothelioma. Pleural effusion caused by collection of fluid between the two linings of lungs and chest cavity may give rise to persistent cough. On chest radiography a build-up of fluid or pleural effusion may be evident indicating viral pneumonia.

The less common symptoms of pleural mesothelioma are:


Chest pain
Pain in the lower back
Difficulty breathing
Coughing
Weight loss
Fever
Muscle weakness and sensory loss
Swelling of the face and arms
Hoarseness of voice
Coughing up blood


A majority of patients do not show any sign and symptoms until late.

Peritoneal mesothelioma

It involves structures like abdomen, stomach cavity, liver, spleen or the bowel. The origin of peritoneal mesothelioma is usually abdomen, from where it spreads to adjoining organs. The symptoms of peritoneal mesothelioma are:


Pain or swelling in the abdomen due to a build-up of fluid
Nausea
Weight loss
Bowel obstruction
Anemia or swelling of the feet
Abdominal bloating due to fluid accumulation in the abdominal cavity
Swelling of the feet
Fever
Impaired bowel function


The symptoms are a consequence of pressure exerted by the growing mass. This growing tumor can also cause breathing problems, and chest pain in addition to these symptoms. These symptoms result from tumors that lean against the abdominal wall. Mesothelioma in peritoneum, owing to its space occupying tendency may give rise to bowel obstruction, anemia, fever and problems with blood clotting.

Pericardial mesothelioma

Pericardial mesothelioma is a very uncommon form affecting the pericardium. Pericardium is the cavity between the linings of the heart. The tumor that grows in the tissue surrounding heart tends to spread from there. Pericardial mesothelioma sufferers may experience chest pain, shortness of breath, persistent coughing and palpitations. Involvement of the membrane around the heart (pericardium) may cause heart rhythm disturbances.

The symptoms for all types of mesothelioma become more acute and obvious with the progression of the disease. In spite of it, it can be mistaken as other disease condition. The only differentiating feature is the history of exposure of asbestos. Therefore, it is critical to investigate one's exposure to asbestos. Symptoms like pain in the lower back or at the side of the chest, shortness of breath, trouble swallowing, cough, fever, sweating, fatigue and weight loss may be very common, but the doctor should elucidate the history of asbestos exposure to rule out the presence of tumor.

Malignant Pleural Mesothelioma is a lethal cancer that starts in the lining of the lungs. They all come to the same conclusion - the disease is almost always fatal. Pleural mesothelioma is the most common form of mesothelioma cancer, accounting for approximately 75% of all mesothelioma cases.

Symptoms

During the early stages of Mesothelioma, the. One of the characteristics of mesothelioma is that symptoms can appear very late, sometimes 50 years following first contact with asbestos. In fact, the first signs of abdominal asbestos mesothelioma may not be noticeable until 20 to 50 years after asbestos exposure. Moreover, the symptoms can vary, depending on several factors, such as the specific type of mesothelioma a patient has and his length of exposure to asbestos. Besides, exhaustion, weight loss and appetite loss are some of the other contributing symptoms. The person who has developed mesothelioma has to be diagnosed immediately when these symptoms are seen. The symptoms and signs of Mesothelioma can be incredibly common that is why the patient may just take it for granted. Diagnosing mesothelioma (within the framework of western medicine) can be challenging, because the symptoms are quite similar to those of other illnesses and conditions.

Most reader know that it is possible to buy ads that will be displayed on Search Engine results pages when certain keywords are searched on. The current record high payment for keyword advertising of this type is held by "mesothelioma" and "asbestos cancer". Mesothelioma is a rare form of cancer that develops by exposure to asbestos. The person who has been exposed to asbestos can claim the compensation from the asbestos firm as a financial security to fulfill the future needs of their family. The infected person can claim the compensation amount from those irresponsible firms that expose asbestos. The Code of Federal Regulations states that asbestos is to be considered a most hazardous toxic substance and you can immediately claim the legal compensation. They will either die from mesothelioma or sarcoidosis. Which are both asbestos cancers which.

Treatment of Asbestos Exposure

However, in more advanced cases, cure is usually not possible. Mesothelioma diagnosis is very important as far as an early treatment is considered. High risk groups such as asbestos and construction workers must undergo frequent check-ups to monitor any conditions leading to mesothelioma. Because this cancer is so deadly, early diagnosis and treatment can help prolong life, but the mortality rate is usually 100% within five years. A Mesothelioma diagnosis can be stressful for anyone and therefore you will have a lot of questions. The following worksheets will guide you in asking the right questions when consulting a doctor about what the right course of treatment is best for you. This tumor as a long lactation period and is often diagnosed 30-50 years after the exposure. The determining factors that needs to be taken into account before the commencement of the mesothelioma treatment are:. These symptoms may also be accompanied by weight loss, fever and difficulty breathing. Unfortunately, once Mesothelioma develops, it quickly becomes aggressive and treatment must be sought immediately. Phase III trials are used to compare a new treatment method with a currently used treatment program. And if a western treatment is chosen as part of the healing protocol, it's important to know what side effects to expect and how to minimize them.

Asbestos Cancer

Mesothelioma, a rare form of lung cancer, continues to remain a challenge for the medical fraternity. This form of cancer is primarily caused by exposure to asbestos. For example, the cough, difficulty breathing, and chest pain experienced in pleural mesothelioma is often seen in lung infections such as pneumonia. Typically, once symptoms are more pronounced the cancer is fairly advanced and treatment becomes less effective. The average survival time is approximately one year, and five-year survival is lower than ten percent. Because of this poor prognosis, the cancer is treated as aggressively as the patient's overall physical condition allows, with some combination of surgery, radiotherapy and chemotherapy. Mesothelioma is the term used to describe a cancerous tumor found in the mesothelial cells of an organ. Generally, the probability of developing this form of cancer is in accordance with the length of time you are exposed to asbestos.

Simple Yet Effective Mesothelioma Treatment Potentially Discovered

Mesothelioma treatment continues to improve on an almost daily basis. There are thousands of researchers across the globe on the cutting edge of cancer research and a good portion of this is applicable to conditions like malignant pleural mesothelioma, a cancer caused by asbestos exposure. Currently, there is no universally successful treatment option for mesothelioma, but researchers have had some recent success.

In a new study published in the Journal of Experimental & Clinical Cancer Research, researchers have discovered a potentially beneficial response to deadly mesothelioma cancer cells. The study is concerned with sodium selenite, the most common water-soluble form of selenium.

Selenium was discovered in 1817 by Jons Jakob Berzelius, as a byproduct of sulfuric acid production. First noticed due to the toxic nature of the element to humans working in industry, it was later found to beneficial as an essential nutritional factor in humans. In 1996, continuing research showed a positive correlation between selenium supplementation and cancer prevention in humans. Selenium in small amounts, such as through a multivitamin supplement, are generally regarded as safe and even beneficial to human nutrition. In large quantities, however, it is toxic to mamamalian bodies, though it is rare that any healthy adult receives more than their daily allotment of selenium.

Selelenium has been shown in several studies to prevent chemically induced carcinogens in rodent studies, though there have been confliciting studies in humans debating the efficacy of selenium supplements. Under the most recent study, sodium selenite has been shown as an antioxidant that can kill mesothelioma cells in cell cultures. Additionally, sodium selenite seems to avoid noticeably damaging healthy cells in the body; this is an enormous step forward in the treatment, as most traditional cancer treatments, such as radiation therapy or chemotherapy, often damage health tissue and cells in the patient's body.

The ramifications of this study are profound; if there is a simple and effective way to address the chronic and deadly condition of mesothelioma cancer and asbestos exposure, it could save the lives of millions of people all over the world. According to reports, the chemical selenite triggered cell death in 15% of sarcomatoid (cancer) cells, compared to just 8% of epithelioid mesothelioma cells. Total cell death after 24 hours of treatment was about 25% in the epithelioid cells and 30% in the sarcomatoid cells. Granted, these results took place in a laboratory setting and actual treatment may be years away. Regardless, this breakthrough provides at least a small amount of hope to those experiencing mesothelioma.

Mesothelioma is a serious and debilitating cancer, oftentimes coming with a grim prognosis. Patients diagnosed with asbestosis, lung cancer, or mesothelioma due to asbestos exposure often find it in their best interest to contact an experienced mesothelioma lawyer. Generally speaking, asbestos exposure results from working in an industry which has either utilized asbestos in manufacturing or production, or has been involved in handling materials containing asbestos, either directly or indirectly. Oftentimes, an experienced mesothelioma attorney can assist the patient with receiving some sort of monetary compensation against the source of their exposure.
