Mesothelioma Tests & Diagnosis

Like with any other illness or serious, terminal disease, the medical tests and confirmation of the existing condition, progression and prognosis, is actually the start of the process of identifying, addressing and effectively dealing with mesothelioma.

A full and detailed review of the patient’s medical history will be taken to enable and effect, underscore and make an accurate diagnosis possible.

Any occupational exposure to asbestos is placed under closer scrutiny. Any work I mines, with some of the products containing asbestos (insulation, cement, HVAC etc, as well as some other professions like construction, engineering and the like), will be considered. These factors will all contribute to a heightened ‘clinical’ hypothesizing about possible origin, root cause of the symptoms.

Diagnostic testing will back up and follow any level of suspicion for mesothelioma.

A full and comprehensive, physical medical examination will follow. Chest X-rays and lung-capacity testing is the logical next avenue of choice. Thickening and presence of fluid will be detected and clearly visible. These will all contribute to more than mere suspicion now for the dreaded mesothelioma.

Next steps will be MRI, CT or CAT scan as they are commonly referred to in the medical community.

Cytology might be performed where lots of the excessive fluids are ‘aspirated’ with a syringe, pleural taps or chest drain, paracentesis or ascitic drain or pericardiocentesis. The method will depend on the location and amount of fluid present – the feasibility of the test procedure. Even if the diagnosis is negative at this point, the data obtained can also be used to rule out other illnesses like TB or heart conditions.

Biopsies are next in line to confirm the diagnosis. A tissue sample through thoracoscopy for example. Looking inside and taking a sample are the goals of this process and outcome.

A Laparoscopy will be done if the lower abdomen or trunk cavity is in question.

Sometimes going deeper would require exploratory diagnostic surgery to determine the nature and extent of the disease, also disease and diagnosis confirmation will be given upon a positive diagnosis

Mesothelioma Tests And Diagnosis Information

There are several tests that doctors can run to determine if a patient has a mesothelioma diagnosis. These mesothelioma tests vary in terms of intrusion into the body and accuracy. A time line for testing a person suspected of having mesothelioma is as follows:

When a patient first presents at the doctors office complaining of difficulty breathing, abdominal pain, or pneumonia types symptoms, the primary care physician will take an X-ray or CT scan to determine the presence of asbestos in or around the lungs, heart or stomach.

Once the detection of asbestos is noted, the doctor will look for tell tale signs of cancer including but not limited to the presence of tumors around the vital organs. If tumors or growths are detected, the primary care physician will typically refer the patient to a specialist for various tests to determine whether there is a mesothelioma diagnosis.

A mesothelioma diagnosis is generally tested for in one of two ways. Depending on the condition of the patient, the doctor may want to do a minimally intrusive procedure called a needle biopsy. The procedure allows the doctor to abstract cells suspected of cancer infection from the lining affected area. The doctor can run tests on the mesothelial cells to determine the proper diagnosis for the patient. There are several ways in which the doctor can perform a tissue biopsy in order to run tests for mesothelioma. A thoracoscopy or laparoscopy entails making a small incision and using a tiny camera to look at the affected area. At this time a small tissue sample can be taken. The tissue samples will be sent away to a pathologists for further tests. Your doctor may decide to do a needle biopsy, where a hollow needle is inserted through the skin and into the chest cavity. However, needle biopsies can be less than precise.

The second more common way that doctors test for mesothelioma is to surgically enter the patients body, at which time they cut a small piece of infected tissue for biopsy purposes. This test is known as an "open biopsy". The abstracted tissue is then sent out for testing by a specialist. This process generally takes several days. If this test reveals the presence of mesothelioma the doctor will determine whether the diagnosed mesothelioma is benign or malignant.

If the doctor determines that the mesothelioma diagnosis is malignant, they will likely refer the patient to an oncologist (cancer doctor) for further tests and treatment.

The oncologist will test the patient to determine the progression of the mesothelioma and the prognosis for the future. At this time the oncologist will decide what treatment option is best for the patient.

Generally, the oncologist will start the patient on a series of chemotherapy treatments to slow the growth of the mesothelioma. If the doctor determines, after running tests, that the patient is not a candidate for chemotherapy, the oncologists may prescribe medication to help the patient with pain management.

Data, Statistics & Information.

Mesothelioma is fairly rare. There are an estimated 2,000 to 3,000 new cases of mesothelioma diagnosed each year in the United States. The incidence of mesotheliomas in the United States increased from 1970 to 1990 and then stabilized. It may now be decreasing. Most of the past increase in cases, as well as the recent decrease in cases, has been in men. The rate of incidence in women although lower, has been fairly steady. In European countries and world wide, the rate of mesotheliomas is still increasing.

Mesothelioma, asbestos & more about this disease.

Mesothelioma is a serious disease. The only known cause of mesothelioma is asbestos. By the time the symptoms appear and cancer is diagnosed, the disease is often in advanced stages. The average survival time is about 1 year. The 5-year relative survival rate is around 10%, but this rate has been slowly improving. Better treatments have resulted in a more favorable outlook for recently diagnosed patients.

Mesothelioma Treatments

With new clinical trials being introduced on a regular basis, there are a variety of treatments being used on mesothelioma. The treatment used is dependant upon a variety of factors, including the extent of the disease, the age and medical history of the patient, and the location and type of the mesothelioma.

The most common treatments are:

Surgery, where the tissue in the affected area is cut out. This may involve removing part of the organ depending on the size of the affected area.

Radiation treatment, which involves the use of radiation treatment to kill off the cancerous cells in the affected area.

Chemotherapy, which is the use of drugs in the body used to kill off the cancerous cells.

Pneumonectomy

A surgical procedure, known as pneumonectomy, can be used for pleural mesothelioma and involves the removal of the diseased lung. An extra-pleural pneumonectomy may be necessary depending upon the spread of the disease, and this may involve the removal of parts of the diaphragm as well as the lung. There is a high risk factor with this surgery, and its viability is dependant upon the patient’s overall health, smoking habits and the extent of the asbestos exposure. A pleurectomy is another type of surgery that may be used, and here part of the chest, abdominal lining and surrounding tissue may be removed.

Radiation treatment

Radiation treatment , which gives the benefit of treating the affected area without exposing the healthy cells and tissue, is another treatment used to treat mesothelioma. This is a speedy and commonly used method for many types of cancer, as well as mesothelioma. It works through the placements of radioactive sources in the affected area, which then give out radiation to kill off the abnormal cells. The radiation continues to transmit for around a year, working to destroy the tumour. Radiation therapy can be used alongside surgery, or if the patient is not well enough for surgery can be used alone.

Chemotherapy treatments

Chemotherapy treatments can be administered in the form of pills or injected medication. The downside of chemotherapy is that the drugs used can contain high toxicity levels and can therefore make patients quite ill. Side effects can include nausea, vomiting, hair loss, weight loss and physical fatigue. There are also a number of post-chemo drugs that are used to alleviate the side effects of the chemotherapy. Because chemotherapy drugs are not targeted towards a specific area, they are left to make their way through the body and find the affected area. This means that they are also able to affect tissue and cells that are unaffected by the disease, which can again cause side effects.

Palliative Therapies

Palliative Therapies may also be used on mesothelioma patients. These therapies entail draining excess fluid from the patient through the use of a needle and suction. To prevent further fluid accumulation drugs may be fed through a tube into the chest following the fluid drainage.

Often, a combination of treatments and a cocktail of drugs have to be used in order to treat mesothelioma patients. Again, the types of treatment used will be dependant upon the age and physical health of the patient as well as upon how far the disease has spread and where it is located.

The above are some of the most common treatments used for the treatment of mesothelioma, but they do not always work effectively on mesothelioma patients. Because of this, sufferers of mesothelioma may be offered treatment as part of a clinical trial as opposed to any of the traditional treatments.

With new mesothelioma cancer treatments are continually being tested through medical research studies, it is hoped that an effective treatment will soon be discovered. These clinical trials enable professionals to asses whether the treatment being tested may one day be effective for general use to treat mesothelioma. And these clinical trials also give hope to the patients who allow themselves to be used as guinea pigs, enabling them to be a part of this important research and find a drug that may help them and others in the same situation.

Mesothelioma Research

Mesothelioma is a disease that is still very hard to recognise, difficult to diagnose and virtually impossible to treat effectively. It is known that the disease is asbestos related and that there is a long latency period before symptoms become apparent. But with more and more cases coming to light each year, it is vital that further research is carried out in order to make this fatal disease more manageable for both patients and doctors.

Many organizations are involved in research in to mesothelioma. This includes the companies that are responsible for the use of asbestos. Many people that have been diagnosed with mesothelioma have now discovered that they can claim compensation for being exposed to hazardous asbestos by companies, which means that these companies have a responsibility to help with this research.

The National Institute of Cancer is also working hard to research mesothelioma, its symptoms, diagnosis and treatment. The rising number of mesothelioma cases means that it is essential to learn more about this disease in order to look into developing treatments.

With many mesothelioma patients now seeking legal advice, it has become essential for law firms to learn about and research the disease. It is the lawyer’s job to assist the mesothelioma patient and provide advice and resources from which the patient can get help and assistance. Therefore, law firms dealing with these types of cases also have a responsibility to learn about the disease and what can be done to help patients.

A great deal of research into mesothelioma goes into learning about the effects of asbestos upon cells, and how the cells are changed by exposure to this material. By learning how healthy cells and corrupted by asbestos, we hope to learn more about how this cell corruption can be prevented or minimised.

The National Institute of Cancer has also carried out clinical trials into the treatment of mesothelioma. The trials, which are performed with real patients who have been diagnosed with mesothelioma, should help to determine how effective the various treatments are, and hopefully will go some way to helping experts find more effective treatments for the disease.

Mesothelioma trials are based upon treatments that are thought to have some value to patients. But the trials are just that – trials. This means that there are no guarantees and that a great deal more work and research will be required before a conclusive and effective treatment is found. On the upside, many new trials are being carried out on a regular basis, and with the information and technology available to scientists today, the discovery of an effective treatment for mesothelioma patients is just a matter of time.

Medical professionals worldwide are currently involved in clinical trials, and each trial depends upon the extent of spread of the disease. Some trials are performed on those who have been diagnosed reasonably early, others on patients who were not diagnosed until the latter stages of the disease. It is important for scientists to find a treatment that is effective not only on those who are diagnosed early, but on all patients that suffer from this killer disease.

The research carried out into mesothelioma will hopefully mean that future generations of suffers can be saved, even if they are diagnosed with the disease. The research carried out is extremely costly, and is often sponsored by associated companies such as drug companies and research groups as well as by the government. Research into the contraction of the disease, and its subsequent development will ultimately enable professionals to devise the most effective treatment.

Several new methods of treatment have been used following research into mesothelioma. These include:

Photodynamic therapy, which uses fixed frequency light to target abnormal cells and kill them off by the activation of photosensitizing drugs.

Immunotherapy, which fights the abnormal cells through the use of the body’s own defence system through enhancement and development of the immune system.

Intensity Modulated Radiation Therapy, which is a radiation treatment that targets just the affected area/tumour, thus avoiding contact with healthy cells and tissue.

Although there is no quick-fix answer to the treatment of mesothelioma, ongoing research and dedication from the medical profession means that the chances of finding an effective treatment are continually increasing.

Symptoms Of Mesothelioma

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.

Mesothelioma

Also called: Malignant mesothelioma

The tissue that lines your lungs, stomach, heart and other organs is called mesothelium. Mesothelioma is cancer of that tissue. It is a rare but serious type of cancer. It usually starts in the lungs, but can also start in the abdomen or other organs. Most people who develop mesothelioma have worked on jobs where they inhaled particles. It can take a long time - 30 to 50 years - between being around asbestos and getting the disease. Treatment includes surgery, radiation, chemotherapy or all three
