Mesothelioma is a cancerous disease that is becoming more and more common. Affecting the mesothelial cells that make up the mesothelium – the outer lining that protects the body’s major organs such as the heart, stomach and lungs – this form of cancer is a direct result of regular and unprotected exposure to asbestos. The symptoms and the latency period of this disease mean that it is difficult to diagnose. Treatment for mesothelioma is still being investigated through clinical trials and research, but as a rule it responds poorly to the treatments that are currently used.

The people most at risk from being carriers of this cancer are those have worked with asbestos over the past thirty to fifty years. Because of this, the disease is most common in men between the ages of sixty and seventy as this is the group that commonly worked with asbestos during those years. Because of the lack of protection and regulations in those days, these workers were constantly exposed to the dust and fibres from the asbestos, which caused the cells of the mesothelium to become abnormal. However, because the disease takes decades to develop fully and manifest, many of them were oblivious to this until thirty to fifty years later. It is these men who are now lodging multi-million dollar lawsuits against the unscrupulous companies that exposed them to the dangers of asbestos, even though they were aware that it could cause harm to the employees.

There are also other people at risk from the disease; namely those who have had regular contact with a person who has worked with asbestos. Because these workers regularly carried dust and fibres on their clothes, skin and in their hair, they fibres and dust could be ingested by family members, who were then at risk of developing mesothelioma, respiratory problems or another asbestos related disease.

The organs most affected by mesothelioma are the lungs and the surrounding tissue. Pleural mesothelioma, which is the type affecting the lining of the lungs, is the most common variation of this cancer with symptoms which include breathing and swallowing difficulties, coughing, shortness of breath, fever and weight loss. The abdomen is another area affected by this cancer, and this variation is known as peritoneal mesothelioma. This type of mesothelioma is not as common as pleural mesothelioma. Symptoms of peritoneal mesothelioma can include nausea and vomiting, weight loss and loss of appetite, fever, bowel obstruction and pain or swelling of the stomach area. The last variation of the cancer is pericardial mesothelioma, which is where the cancer affects the heart and the tissue surrounding it. This variation is a rare one, and symptoms can include palpitations, breathing difficulties, and persistent coughing.

The symptoms of mesothelioma are very common to a number of other diseases which are more well-known in society. Therefore, it is not unusual for the patient to be misdiagnosed when he or she goes in displaying any or all of these symptoms. People who have worked with asbestos should always let their doctor know this so that the doctor is more aware and more conscious of the possibilities in the event that the symptoms do manifest. A speedy diagnosis is important to the effective treatment of mesothelioma, and without being aware of the facts your doctor may not be able to make the diagnosis as quickly as he would if he is aware of the situation.

Although there are treatments for mesothelioma, they do not have a high success rate particularly on patients in whom the cancer is in its later stages. The faster the mesothelioma is diagnosed and treated, the more chance of success, which is why it is important to get as fast a diagnosis as possible.

Current treatments for mesothelioma include surgery, radiation therapy, palliative therapy and chemotherapy. The National Institute of Cancer along with a variety of other organizations and sponsors are currently conducting research into mesothelioma and carrying out clinical trials to try and find a treatment that will not only be more effective but will enable the successful treatment of the disease even in its later stages.

The long latency period attached to mesothelioma means that the symptoms of this disease can take many years to manifest, making both diagnosis and effective treatment very difficult. And even when the symptoms do become evident, which can take several decades, the symptoms are so generalised and non-specific that they could be put down to any number of more common diseases. This makes it hard for even experienced doctors to make a quick and conclusive diagnosis with mesothelioma patients. The symptoms of this disease can often be confused with pneumonia during its early stages.

Some of the most common symptoms of pleural mesothelioma (which is the most common form of the disease) are shortness of breath and chest pains. This may be accompanied by a persistent cough, and all of these symptoms stem from the build up of fluid between the lining of the lung and the chest cavity. This is known as pleural effusion. This type of the disease starts in the chest cavity and can then spread to other parts of the body. Pleural mesothelioma sufferers may also begin to display severe breathing difficulty, weight loss and fever as well as trouble swallowing and even swelling of the face and neck. Some patients may also develop a rasping voice and start coughing up blood. However, there are other patients that may not show any significant symptoms at all.

The symptoms for patients who suffer from peritoneal mesothelioma (a rarer form of the disease) are slightly different. This type of the disease starts in the abdomen and can spread form there. Patients of peritoneal mesothelioma can display abdominal pain and swelling, nausea, loss of appetite and vomiting. They can also suffer breathing problems, and chest pain in addition to these symptoms. These symptoms result from tumours that lean against the abdominal wall. Bowel obstruction, anaemia, fever and problems with blood clotting may also affect peritoneal mesothelioma patients.

The rarest form of this disease is pericardial mesothelioma, which starts in the cavity surrounding the heart. With pericardial mesothelioma, the tumours grow in the tissues that surround the heart and can spread from there. Pericardial mesothelioma sufferers may experience chest pain, shortness of breath, persistent coughing and palpitations.

As the disease moves into the later stages, the symptoms for all types of mesothelioma become more acute and obvious, although they can still often be put down to another illness. It is therefore important for patients to inform their doctor if they have been exposed to asbestos at any point – or even if they suspect they may have been exposed to asbestos. This will enable the doctor to make a more informed diagnosis rather than basing his diagnosis on guess work. It is also important not to ignore any of these symptoms, especially if they are experienced over a long period. Many people can be exposed to asbestos inadvertently (e.g. through the clothes of someone that has worked with asbestos) so it is important to visit your doctor should any of these symptoms manifest.

With pleural mesothelioma being the most common form of the disease, the symptom associated with this form of the cancer are the most common ones that are displayed by patients. However, it is important to be fully aware of the symptoms for all three types of mesothelioma, particularly for those who have worked in high risk professions where they may have been exposed to asbestos.
Most people who have worked with asbestos in the past do not begin to show symptoms of mesothelioma until thirty to forty years later. By this time, the disease is already spreading and with the delay in diagnosis, makes it impossible to treat in many cases before it is too late. However, the cause, effects and symptoms of mesothelioma are now becoming more widely known by professionals and lay people. This awareness, coupled with the current clinical trials that are being carried out by a variety of organizations gives patients the hope that an effective treatment will one day be available for all stages of the disease.
