A Closer Look at Peritoneal Mesothelioma Cancer
Posted by admin in Info Cancer Mesothelioma on October 7, 2011
Peritoneal Mesothelioma is a kind of cancer that commonly occurs due to increased exposure to asbestos for a long period of time. There are findings that this cancer develops even without asbestos exposure. This type of cancer affects the peritoneum, which is the lining that protects the internal organs of the abdominal cavity. The peritoneum is made up of mesothilial cells which are the cells affected by cancer. It is a rare form of mesothelioma. Pleural mesothelioma, which is the cancer of the mesothelial cells of the covering of the lungs, is the more common form than the peritoneal mesothelioma.
Asbestos is a material used for insulation, which is resistant to heat and fire. It is used in the construction or engineering of buildings, ships, household appliances and motors. It has been reported that there is a higher incidence of mesothelioma in males because this type of caner is work related. Males are commonly hired for the construction or engineering of buildings, ships, motors and household appliances which causes the increased incidence of mesothelioma in males.
THE CULPRITS
There are three types of asbestos namely the blue, white and brown. These are all linked to cancer which caused asbestos to be banned in many countries such as the UK. Asbestos is made up of tiny fibers that can be breathed into the lung. It then works its way to the pleura irritating and damaging the mesothilial cell. Some asbestos might be coughed up as a defense of the body to get rid of the irritating foreign body that has entered the lung. When this happens the asbestos goes to the mouth and is then swallowed. It then works its way to the internal organs of the abdominal cavity irritating and damaging the peritoneum or the mesothilium, which the tissue made up of mesothelial cells that covers the internal organs. Upon exposure to asbestos, the fibers are deposited in the clothing of the worker. The worker exposed to asbestos spreads it to his family when he gets home through his clothing. This puts the family at high risk to developing mesothelioma since they are also exposed through asbestos.
There are also less common causes of mesothelioma. It has been found out that exposure to radiation can also cause pleural and peritonieal mesothelioma. Thoratast or thorioum dioxide was used in x-ray tests in the 1950s. Exposure to a mineral in turkey, which is called the Zeolite can also cause the cancer mesothelioma. The virus SV40 also known as the simian virus increases the risk of developing mesothelioma. It acts as a co-factor when the person is exposed to another risk factor, amplifying the possibility of developing mesothelioma.
GETTING CHECKED
It is not easy to diagnose mesothelioma. There is no specific screening for mesothelioma. People who are high risk to develop mesothelioma should be checked periodically in order to spot mesothelioma at the earliest stage possible so prompt treatment may be done. There are some signs and symptoms the doctors watch out to get further tests to confirm mesothelioma. Pain, swelling tenderness to any area and a possible lump are the common complaints that are considered.
Blood test is then done to evaluate the person’s general health. If doctor suspects that the person may have peritoneal mesothelioma, the person may have abdominal x-ray, abdominal CT scan or abdominal MRI scan to check and confirm for swelling and fluid accumulation in the abdomen. Abdoparacentsis or fluid drainage from the abdomen may be done to relieve the swelling and pain around the abdomen and to see if there are malignant or cancerous cells in the fluid. Laparoscopy or biopsy of the abdominal lining or peritoneum may be done, wherein they get a tissue sample of the abdominal lining and check if the mesothelial cells are damaged by cancer.
If these tests confirm that one has peritoneal mesothelioma, it is then evaluated if it has spread to other parts of the body. This is called staging or determining the gravity of the cancer itself. This process is very important to determine what action or treatment will be done. A PET scan may be done to see how the cells are working. PET stands for positron emission tomography. This is done if the peritoneal mesothelioma cancer is treatable through surgery. This shows the extent of spread of the cancer cells to the other parts of the body like the lymph nodes and other organs.

What Are The Four Stages of Mesothelioma Cancer?
Posted by admin in Info Cancer Mesothelioma on October 7, 2011
One rare form of cancer is called Mesothelioma, a malignant tumor in the mesothelial tissues of the lungs and the abdomen, arising from the inhalation of asbestos. Its rarity is one of the reasons why a lot of people are not aware of this kind of fatal disease. In fact, many people die of Mesothelioma undiagnosed. Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma — fifty years, at most.
Being unaware of Mesothelioma poses higher risks since it deters diagnosis and treatment. A person undergoing treatment must know the different stages of the cancer or the extent of the disease. Chances of recovering from Mesothelioma and the kind of treatment depend on the stage of the illness. There are basically two staging systems used for Pleural Mesothelioma (lungs): TNM system and Brighan system. These staging systems are also used in other kinds of cancers; however, the first is commonly used. There is no established method in determining the stage of the Peritoneal Mesothelioma cancer (abdominal) so the TNM system is used.
There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage I, the malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage I Mesothelioma.
In the second stage, the two layers of the pleura are already affected by Mesothelioma. Take note, however, that in this stage, only one side of the body is affected. Normally, the pleura produces only small amount of lubricating fluid that allows easy expanding and contracting of the lungs. The excess fluid is absorbed by the blood and the lymph vessels so there’s a balance between the amount of fluid produced and removed. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain. Other Mesothelioma cancer patients experience dry and persistent cough. Diagnosis of the pleural effusion is achieved through a chest x-ray.
Stage III Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn’t respond well to medication, the cancer may advance to the fourth stage. The fourth stage Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage IV.
Brighan staging system, on the other hand, determines whether the Mesothelioma can be surgically removed or not and whether the lymph nodes are affected or not. In stage I Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery. In stage II, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells. In stage III, the heart and chest wall are already affected; thus, surgery is no longer advisable. The lymph nodes in this stage, however, may or may not be affected. In the final stage, stage IV Mesothelioma, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. In most cases, a patient who has reached stage IV Mesothelioma only has four to twenty-four months to live.

Mesothelioma Cancer Definition
Posted by admin in Info Cancer Mesothelioma on October 7, 2011
The diagnosis of cancer is not always rapid and accurate. Oftentimes, the condition is diagnosed only when cancer cells have already proliferated in the organ. The Big C is one of the most dreaded diseases because mortality is usually high and the prognosis is poor.
Mesothelioma Cancer Definition:
Mesothelioma is a type of cancer caused by the inhalation of asbestos, which is a seemingly useless material ignored by most people. It is called mesothelioma cancer because it affects the outer covering of vital organs, the mesothelium. Examples are the peritoneal, pericardial and pleural membranes
The signs and symptoms usually appear decades after the onset of the cancer itself, and is sometimes taken for granted because its symptoms are mostly the same with less serious illnesses.
Diagnosis of mesothelioma
The progress of mesothelioma depends on the distance of the metastasis from the point of origin. Diagnosis is done through biopsy of the patient’s infected part. It is screened through the determination of serum osteopontin level and significant amounts could indicate mesothelioma.
There are three types of mesothelioma, the most common type is the pleural mesothelioma which involves the lining of the lungs. This is caused by asbestos exposure. The workers of a manufacturing company dealing with asbestos are the first victims due to direct contact and inhalation of its fibers. This type of cancer is more common in males than in females. This causes chronic inflammation that will develop into malignant tumors after years.
The second is the Peritoneal mesothelioma. This type of mesothelioma affects the peritoneum and the last is pericardial mesothelioma which affects the covering of the heart or the pericardium.
Some studies imply that the development of mesothelioma in one individual is affected by SV40 or Simin Virus 40. In rare cases, mesothelioma cancer definition is associated with irradiation and inhalation of fibrous silicates. Mesothelioma is not a smoking-associated cancer like in lung cancer but it can aggravate the risk of asbestos-induced cancers.
Some of the treatments available nowadays are chemotherapy, irradiation therapy and surgery. But the most effective way on how to avoid cancer is prevention from acquiring it.
Mesothelioma cancer definition can be ambiguous because of the lack of proper diagnosis during the early stages of the disease. This type of cancer is uncommon and people working in an asbestos-procuring or manufacturing company should be aware of the hazards of their job so they can implement proper action to solve the problem.

Mesothelioma – What is Mesothelioma Cancer?
Posted by admin in Info Cancer Mesothelioma on October 7, 2011
Mesothelioma cancer is a rare cancer that is thought to come from the inhalation of asbestos fibers as well as exposure to asbestos. People that have work concerning plentiful amounts of asbestos are in danger of contracting mesothelioma. Studies have reasonably shown that the vast majority of those that have mesothelioma had exposure to asbestos at some point in the past whether it was work-related or otherwise.
Mesothelioma is also a relatively rare form of cancer with only about 4000 cases each year. The three major varieties of mesothelioma all match up to the area of the mesothelium that is affected. They are known as Pericardial, Peritoneal and Pleural Mesothelioma.
The cancer is named after the mesothelium, which is a protective membrane that covers various cavities. Peritoneal, Pleural and Peritoneal mesothelioma are all named after the particular cavities that this cancer affects. The symptoms for each are different.
These symptoms generally show up much later on in the future after exposure to asbestos. Weight loss, abdominal pain as well as abdominal lumps are all symptoms of peritoneal mesothelioma. Pleural Mesothelioma symptoms include shortness of breath, cough (dry), lumps in the chest region, chest pain, painful breathing and coughing. Pericardial Mesothelioma symptoms are chest pains, fever, heart palpitations, difficulty breathing, murmurs, Orthopnea. It should be noted that smokers that have been exposed to asbestos have a higher than normal chance of contracting pleural mesothelioma.
In rare cases, if the cancer is caught exceedingly early, the cancer may be sent into remission. Otherwise, mesothelioma patients experience abysmal survival rates. Those suffering from advanced stages of mesothelioma usually have a year or so to live.
Those fortunate enough to uncover the cancer in its early stages can expect to live for up to 5 years. There is still research being done in the field, albeit not a whole lot. The well-known specialist, Dr.David Sugarbaker and other notable doctors elsewhere represent the few doctors that are making inroads into unraveling the mysteries of this cancer. The main areas of research tend to target pleural mesothelioma and new, aggressive techniques have been found to lengthen live expectancy by years. While a cure has still not been found for any type of cancer much less mesothelioma, there is constant research being done in the area.
