MESOTHELIOMA

The malignant detection of mesothelioma, like other cancers, can be accomplished with the equipment of formation image, such as machines of x-ray. But once detected, the diagnosis of mesothelioma is difficult for a certain number of reasons. Initially, one period ago of time very prolonged between the exposure to asbestos and the beginning of the disease, sometimes as long as 50 to 60 years. The patients would often not think to say their doctors about work in a asbestos-related work much of years earlier.

In the second place, the typical symptoms of the mesothelioma, brevity of breath and cough, are also symptoms of many of other types of problems of lung, cancer patients and non-cancerous. Thus, just because a person has these symptoms, it does not provide a some way a diagnosis of mesothelioma.

Thirdly, much of types of tumours can exist in the cavities serous which are not mesothelioma. These other types of tumours can be not cancer patients, or benign, who come from fabrics of the membranes serous, other that the mesothelium. Or they can be tumours which emigrated of other bodies with cancerous growths due to metastases.
Mesothelioma and technologies of the image

X-rays and other types of technologies of the image can be employed to detect the tumours or overflowing (accumulation of fluid) in the body, including the detection of mesothelioma. A growth of the cavity of trunk will appear in a x-ray or MRI analyzes it. But these devices cannot directly determine the type of cancer or provide a diagnosis of mesothelioma. They cannot determine if the tumour is mesothelioma or comes from another source.

The tomography of emission of positron (ANIMAL FAMILIAR) is a diagnostic type of sweeping of formation image which is employed for the malignant detection of mesothelioma. Sweepings of FAMILIAR ANIMAL employ the emission of the positrons (tiny particles which are emitted radioactive substances) in order to it detection of radiation.

Some medical professionals are impression which sweepings of FAMILIAR ANIMAL are the most effective method by which to check a case of mesothelioma definitively. While they believe that the techniques of formation standard image like x-rays and MRIs should continue to play a part by diagnosing the disease, it is estimated it that the tomography of emission of positron becomes an increasingly valid tool in the scaffolding and the typewriting of the latent asbestos cancer.
Diagnostic surgery - biopsy

To provide a diagnosis of mesothelioma, a biopsy is necessary. This biopsy undergoes then what is called the diagnostic histopathology. The histopathology is a technique where the cells of the tumour are looked under a microscope high power, or electronic microscopy. Electronic microscopy is considered the gold standard for the material of evaluation of tumour of a biopsy. It is a strongly advanced microscope which allows the viewing of the tiniest elements of fabric of cells.

For the diagnosis of mesothelioma, a pathologist (a doctor who specializes in the detection of the disease) place cells of tumour in the electron microscope and then looks at the structure of the various cells. The cells of mesothelioma have a specific form and a model, and this enables them to be identified by a very sharp pathologist. But the cells of mesothelioma seem also similar to other types of cancer cells, such as cells of adenocarcinomist, and this can return the pathologist the 'work of S very difficult. Even with the electron microscope, it can be difficult to recognize the various types of cells of mesothelioma. The three types of cells are epithelioid cancer cells of mesothelioma, which are tubular in the form, the cancer cells sarcomatoid of mesothelioma, which are oval and of irregular form, and of the two-phase cancer cells of mesothelioma, which are a combination of the forms. These cells can be confused with other types of cancer cells.
New methods for detection of mesothelioma

Because of this diagnostic confusion, much of research is in hand to find new methods for the diagnosis. A method is to evaluate the types of made up produced by the cancer cells of mesothelioma. This is called the histochimy. Histochemical reactions were employed a long time to distinguish standard mesothelial and others from cells of tumour. For example, of the cells mesothelial are known to produce the specific types of made up of carbohydrate. Unfortunately, other types of cells in the body also produce these compounds.

The immunochimy also is employed to detect the mesothelioma. This field of study evaluates the presence of the antibodies in the body. Certain types of antibody are known to be associated with certain types of cancer. But the cells mesothelial do not have any specific type of antibodies which can provide has positive marker. Consequently, the immunochimy allows the doctor eliminates it another cancer, but does not indicate the presence of the mesothelioma. These techniques offer perspicacity in the disease and can help to eliminate from other diseases, but none can directly detect the mesothelioma.
New blood tests for the detection of mesothelioma

Protein of SMR: Recently, because of the difficulty by diagnosing the malignant mesothelioma, research concentrated on finding new means of detecting the presence of the disease. The researchers in Australia noted that a certain protein, called SMR or the related protein by soluble Mesothelin, is high in the patients with the mesothelioma. These researchers proposed that a test for the presence of SMR in blood could represent a useful marker for the progression of diagnosis and disease. They estimate that such diagnostic tools could lead to a detection earlier, and thus a more effective treatment.

One of the results more seizing of their research was that several asbestos-exposed people who examined the positive one for SMR were diagnosed with the mesothelioma within three year. They proposed that the evaluation of SMR can help to identify people in danger to this fatal disease. Moreover, they noted that the levels of SMR increase as the mesothelioma progresses, suggesting that the evaluation of SMR could be employed to detect the progression of the disease and the effectiveness of the treatment

Glycoprot�ine d' Osteopontin: In an effort to produce the first early-detection examine to examine for the malignant mesothelioma, the researchers at the university of the State of Wayne had studied the possible bond between the development of mesothelioma and the levels of a glycoprot�ine called the osteopontin. The clinical results early of study of 190 patients showed a bond between the elevated levels of the osteopontin and the development of the malignant pleural mesothelioma.

Although the results are looked as a preliminary, there is much excitation surrounding the potential of an analysis of blood able to examine for the mesothelioma with its parts. While there is no treatment known for the malignant mesothelioma, research is continuous and certain successes were already carried out in terms of time of survival of widening beyond that with the two years average of post-diagnosis. It is hoped it that if the specialists in mesothelioma have more time it where to lead the treatment on a little forms developed asbestos cancer, the largest one patient 'chance of S to potential survival.
