Mesothelioma Diagnosis & Tests - PET Scans Some doctors may also order a positron emission tomography (PET) scan. The PET scan may reveal areas where there is abnormal, perhaps cancerous, tissue. PET scans are used in situations where there may be scar tissue present and are used in conjunction with CT scans in many cases. They are also often used to find the stage of cancer. With a PET scan, a radioactive substance is injected into the blood. This substance is usually a type of sugar related to glucose. After some time, the scanners can detect and will show images of the tissue that is interacting with the substance. Due to the quick growth activity of cancer cells, they absorb more of the injected substance compared to other healthy cells. Even though the picture results from a PET scan are not as detailed as a CT or MRI scan, they can provide doctors with very helpful information regarding if abnormal areas are cancerous or not. Many doctors use this test to see if the ...

Mesothelioma Diagnosis & Tests -  Chest X-Rays  One of the usual first steps to a mesothelioma diagnosis is a chest x-ray. A chest x-ray may show a buildup of fluid in the lining around the lung and is a quick procedure that requires no preparation. A chest X-ray is performed by a radiology technologist. Before the x-ray, the technologist may ask you to remove your clothing from the waist up and remove all jewelry or other objects containing metal. This can block images and compromise the test results. Your body will be positioned against the X-ray film and the technologist will take images from two positions: Back to front (called a posterior-anterior, or PA, view) The side (called a lateral view) Each of the positions only lasts just a few seconds so the x-rays are taken quickly. The amount of radiation from a chest X-ray is low—even lower than what you're exposed to through natural sources of radiation in the environment, says the Mayo Clinic. In short,...

How is Mesothelioma Esothelioma Diagnosed? Mesothelioma is not easy to diagnose. There are multiple tests that doctors may use to diagnosis mesothelioma including: Chest X-Rays Computed Tomography (CT) Scans PET Scans Pathological Evaluation Cytology Thoracoscopy Biopsy A chest x-ray may show a buildup of fluid in the lining around the lung. The doctor may order a CT scan for further evaluation. A CT scan can also determine if fluid has built up inside the lungs. Some doctors may order a PET scan. The PET scan may reveal areas where there is abnormal, perhaps cancerous, tissue. After the CT and/or PET scan, a doctor may perform a biopsy or cytology to make a definitive diagnosis. If a biopsy is performed, a tissue sample taken from the body will be reviewed under a microscope to determine if the tumor is benign (non-cancerous) or malignant (cancerous). The tissue will often be "stained" to determine the type of cancer and examined to determine the typ...
