About Mesothelioma, Its Symptoms, Causes and Treatment
About Mesothelioma -
Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.
What is the mesothelium?
The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.
How common is mesothelioma?
Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.
Mesothelioma Symptoms
Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.
These symptoms may be caused by mesothelioma or by other, less serious conditions. It is important to see a doctor about any of these symptoms. Only a doctor can make a diagnosis.
The early symptoms of mesothelioma are often ignored, because they may be caused by a variety of ailments. These symptoms include:
pain in the lower back or at the side of the chest
shortness of breath
difficulty swallowing
cough
fever
fatigue
abdominal pain, weight loss , and nausea and vomiting (symptoms of peritoneal mesothelioma)
Causes of Mesothelioma -
The primary risk factor for developing mesothelioma is asbestos exposure. In the past, asbestos was used as a very effective type of insulation. The use of this material, however, has been declining since the link between asbestos and mesothelioma has become known. It is thought that when the fibers of asbestos are inhaled, some of them reach the ends of the small airways and penetrate into the pleural lining. There the fibers may directly harm mesothelial cells and eventually cause mesothelioma. If the fibers are swallowed, they can reach the abdominal cavity, where they can contribute to the formation of peritoneal mesothelioma.
Exposure to certain types of radiation as well as to a chemical related to asbestos known as zeolite has also been related to incidences of mesothelioma.
Mesothelioma Treatment -
Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient's age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined. Surgery is a common treatment for mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.
Seeking Mesothelioma Help
If you, or someone you know has been diagnosed with, or thinks that they might have Mesothelioma Cancer, it is often daunting and can be difficult to know where to seek help. However, you are not alone, there are organizations and doctors who can help.
With the current research and new knowledge about Mesothelioma Cancer, seeking help has become easier, as there are now established support organizations and more knowledgeable doctors who can help you, your friend, or your family.
In most Mesothelioma Cancer cases, the disease has developed as a result of exposure to an Asbestos related substance. In most cases people who develop Mesothelioma Cancer worked directly with an asbestos related substance, or were exposed to an Asbestos related substance, over a long period of time, in their place of work.
Early intervention provides sufferers of Mesothelioma Cancer their best chance of survival, following appropriate treatment. This is why it is important that if you, or someone you know, are experiencing the effects of Mesothelioma Cancer, you should seek help.
Some of the types of symptoms that you should be looking for include, coughing, breathlessness, chest pain, abdominal pain and fatigue and immune deficiency related illnesses, such as colds.
If you think you have any of these symptoms, you should make an appointment you’re your local GP and seek a referral to a Mesothelioma Cancer Specialist. If you are then diagnosed with Mesothelioma Cancer you might then consider contacting a Mesothelioma Attorney, or Lawyer.
Some of the support organizations that you might consider contacting include, the American Cancer Society, who can provide information about other support networks in your area.
If you, or someone you know, has been diagnosed with Mesothelioma Cancer, there is no need to suffer in silence, as there are many positive steps you can take towards securing your future, there is always help to be found.
Currently, there are new treatments for Mesothelioma being discovered and implemented and through greater knowledge and early intervention; these new treatments are proving to be effective.
Of course, being diagnosed with Mesothelioma Cancer can be a difficult time for both you and your family, however, there are many Cancer support agencies that also offer support to the families of Cancer victims.
Research has shown that early intervention and treatment of Mesothelioma Cancer has helped many patients live up to 7 years beyond their expected survival rate, without seeking help and undergoing treatment.
So, we encourage you to take the time to seek help if you have been exposed to, or diagnosed with Mesothelioma Cancer. It will be a positive step towards saving your own life, or that of another.
Easy Steps to Prevent Mesothelioma
Mesothelioma is a rare cancer that attacks the body's mesothelial cells around the organs. The mesothelium provides a protective membranous lining for the internal organs and allows moving organs (i.e. the heart and the lungs) to glide easily against adjacent structures. The names of the three regions of mesothelial cells that provide protective coating are 1) pleura, the sac which surrounds the lungs; 2) peritoneum, the lining which protects the abdominal cavity; and 3) pericardium, the sac which surrounds the heart. Three different types of mesothelioma cancer attack these three different regions.
Pleural mesothelioma: A type of lung cancer which attacks the pleura surrounding the lungs, this is the most common type of mesothelioma, affecting approximately two-thirds of all mesothelioma patients. Symptoms include horseness, fever, blood in sputum, swollen arms and face, coughing, loss of weight, difficulty breathing, chest pain, weak muscles, and reduced tactile sensitivity.
Peritoneal mesothelioma: A cancer of the abdomen which attacks the peritoneum lining the abdominal cavity. This affects approximately one-third of all mesothelioma patients. Symptoms include abdominal bloating, impaired bowl function, fever, swollen feet, and nausea.
Pericardial mesothelioma: This form of mesothelioma which attacks the pericardium surrounding the heart is extremely rare. Symptoms include chest pain, dyspnea, cough, and palpitations.
Mesothelioma has been linked to asbestos exposure. Asbestos is a type of building material used in thermal insulation products and ceiling tiles. In the United States, asbestos usage peaked during the 1950s - 1970s. During the late 1960s, concerns over the health consequences of asbestos exposure began to arise, thereby decreasing the amount of asbestos manufactured in next two decades. By the 1980s, a new industry of asbestos abatement began to flourish. But according to the United States Environmental Protection Agency (EPA), as many as 733,000 schools and public buildings still contain asbestos.
Small asbestos fibers that enter the air do not evaporate and can remain suspended in the air for a long time. These fibers, when breathed into the body, are toxic. There are three types of asbestos exposure.
Occupational asbestos exposure: People working in factories that manufacure asbestos are likely to have a high exposure to asbestos and are most at risk of developing asbestosis or mesothelioma.
Paraoccupational asbestos exposure: Family members of workers exposed to asbestos in the workplace are susceptible to exposure from asbestos dust brought home by the worker on his clothes or skin.
Neighborhood asbestos exposure: Those who live in the vicinity of an asbestos manufacturing plant are also at risk.
Mesothelioma is still a relatively rare form of cancer. There are an estimated 2,000 - 3,000 new cases per year in the United States. Approximately 7-13 per one million male patients with a history of asbestos exposure contract mesothelioma. Diagnosis usually occurs 20-40 years after initial exposure to asbestos.
