Malignant Mesothelioma Diagnosis

When a patient has symptoms suggesting malignant mesothelioma, a doctor starts with imaging techniques to confirm a diagnosis. X-rays and CT scans of the chest or abdomen are taken to identify any abnormalities, such as fluid collections, thickening of tissue, or growths, that may indicate underlying disease. Magnetic resonance images (MRI) or positron emission tomography (PET) images are taken to determine the extent of spread of a cancer; PET is most expensive but also the most accurate. Information from scans is used to plan appropriate treatment.

Once cancer is suspected, a tissue biopsy is needed to confirm the diagnosis. If the pleura or tissue lining the chest and lungs is involved, a thoracoscopy is performed, usually under local anesthesia. A small opening is made in the chest wall and an instrument called a thorascope, through which the surgeon can see into the chest, is inserted between the ribs. Tissue and fluid can be collected through this opening. Similarly, if the peritoneum or tissue lining the abdominal cavity and abdominal organs is involved, a peritoneoscope is inserted into the abdominal cavity to collect biopsy tissue. The biopsy tissue is then examined under a microscope to find out if the cells in it are normal or cancerous. Depending on the cell type, a diagnosis of malignant mesothelioma can be made. Malignant mesotheliomas are of three cell types: epithelioid, mixed and sarcomatoid. In general, epithelioid malignant mesotheliomas are the most common and carry the best prognosis; sarcomatoid ones are the most rare with the shortest survival time.

The next step is to stage the cancer as localized, advanced or recurrent. This may be done through a combination of imaging and surgical exploration. There are three staging systems in use, each with four stages: the Butchart System, the TNM System and the Brigham System.

Diagnosis of malignant mesothelioma

If a patient has symptoms suggested malignant mesothelioma, a doctor starts with imaging techniques to confirm the diagnosis. X-rays and CT of the chest or abdomen are taken at any abnormalities, such as water retention, detect thickening of the tissue, or growths, which may indicate an underlying disease. magnetic resonance imaging (MRI) or positron emission tomography (PET) images are taken to determine the extent of tumor spread, PET is the most expensive, but alsoaccurate. Information from scanning is used to plan appropriate treatment.

Once a suspicion of cancer, a biopsy is needed to confirm the diagnosis. When the pleura or tissue along the chest and lungs are involved, a thoracoscopy is performed, usually under local anesthesia. A small opening in the chest wall and an instrument called a scope of the chest through which the surgeon can see inside the breast to be inserted between the ribs. Tissues and fluids can be raised by thisOpening. The same applies if the peritoneum or tissue lining the abdominal cavity and abdominal organs is involved, is a peritoneoscope introduced into the abdomen to collect a tissue biopsy. The biopsy tissue is then examined under a microscope to determine whether cells are normal or cancer. Depending on the cell type, the diagnosis of malignant mesothelioma can be made. epithelioid malignant mesothelioma are three types of cells: mixed and sarcomatoid. Generallyepithelioid malignant mesothelioma are the most common and carry the best prognosis; sarcomatoid rare are those with the shortest survival time.

The next step is localized cancer, recurrent or advanced. This can be done through a combination of imaging and surgical exploration. There are three staging systems in use, each with four stages: the Butchart System, the TNM system and the Brigham System.

Mesothelioma Diagnosis - Four Tests May Confirm Asbestos Cancer

Image : http://www.flickr.com

Getting your mesothelioma diagnosis is just the beginning of your journey, but there's a lot to learn before you hear the official word from your doctor. To be absolutely sure that you have been exposed and affected by asbestos, you need to have a battery of tests that will help you and your doctor feel certain about your mesothelioma diagnosis.

Here are some of the most common ways of testing for mesothelioma in your body, starting from the least invasive test to the most invasive:

Chest X-Ray A chest x-ray is simply a way to take a picture of your lungs without having to do anything invasive. From this x-ray film, a doctor will be able to diagnose if there is any thickening of the lung tissue, which is often a sign of mesothelioma. If you've been recently exposed to asbestos, this may not show up immediately, but these kinds of results do signify that something dangerous is happening to the lung tissue.

CT Scan If the initial chest x-ray looks suspicious, the next usual step is a CT scan. If a CT is not available, a doctor may also order an MRI. What this does is point out the fluids that are present in the body. If there is a lot of fluid in the lungs, it may be a sign of a mesothelioma diagnosis and asbestos exposure.

Pleural and Peritoneal Aspiration

When the CT or the MRI shows a lot of fluid in these parts of the body, you can also aspirate, or draw out the fluid with a needle to see if it contains any cancerous cells. This sample is sent to pathology for examination, but if there are no cancerous cells, that doesn't mean that you're necessarily in the clear either. It can mean that you have some other diagnosis than mesothelioma.

Biopsy If you have an obvious mass in your lungs or in your abdominal cavity, the doctor might want to take a part of it to examine for cancerous cells, called a biopsy. This allows the doctor to see if the cancer has spread to this part of the body.

With these various tests and procedures, a doctor will be gathering the evidence needed to make a conclusive mesothelioma diagnosis. There may actually be something else going on that's simply similar to the symptoms you may be having, so you want to rule out mesothelioma cancer as a possibility.
