Lung Mesothelioma

How is made the diagnosis of mesothelioma?

The diagnosis of mesothelioma

We have already explained in other articles what the disease is, what are the risks and what symptoms. Now we discuss how the diagnosis can be done, or how it’s done.

Several tests are done to diagnose the disease. Among which are found:





Immunohistochemical studies

The diagnosis of mesothelioma can begin with a suspicion through imaging, but this is only confirmed by a biopsy because there must be a clear distinction between mesothelioma and other pleural diseases (such as carcinoma of the lungs, pleural metastasis, or other cancers).

First of all, when a doctor suspects something, you must first ask the medical history of the patient. And if there is a history of asbestos exposure should serve as a red alert. Once it is confirmed the patient’s exposure to asbestos, this should be automatically forwarded to an x-ray to the chest and lung function tests.

If the X-ray shows pleural thickening, suspected mesothelioma increase significantly. This is where the patient is referred to perform one o’clock CT scan (also called CAT) or an MRI. If the patient shows a large amount of fluid present in the lungs is removed with some of that liquid syringe through cytopathology to detect abnormal cells.

However, even if the patient does not have abnormal cells in the cytology, this does not exclude the diagnosis of mesothelioma immediately, although it is much more unlikely. Therefore, the biopsy is not excluded in cases in which there is shown fluid in the lungs.

Biopsy serves, for the most part, only to confirm the diagnosis of malignant mesothelioma. The process consists of removing a piece of tissue for microscopic examination by a pathologist. When the fabric is taken out of the lungs, the pathologist performs a thoracoscopy or when made by a surgeon a thoracotomy.

If the cancer is in a laparoscopy abdomen is made to obtain a tissue sample from the abdominal cavity. If not get an amount sufficient tissue for the biopsy is taken, then the patient undergoes surgery for removal of a sufficient sample.

The Immunohistochemical studies are important for the pathologist difference between malignant mesothelioma and neoplastic mimics.

When we perform a diagnosis of mesothelioma, it is still analyzing the different subtypes of the disease.




About 75 to 95 percent of cases of mesotheliomas are epithelioid and biphasic.

In any event, diagnosis of mesothelioma is done in the same way.
