Testing fluid and tissue samples

If fluid build-up in the chest, abdomen or heart area is present, your doctor may want to obtain a sample. To accomplish this he/she will use a long needle to obtain fluid from the target area. The fluid will then be sent to the lab for analysis.

A bronchoscopy procedure may be recommended for patients who are suspected of having pleural mesothelioma. For this medical test, a soft tube illuminates the trachea and bronchi to determine if any masses are present in the airways. If deemed necessary, the technician my take sample of tissue that appears to be abnormal for further testing.
If lymph node involvement is suspected which is common with lung cancer, patients may also undergo a mediastinoscopy. This procedure is similar to a bronchoscopy in that a soft tube enters the body under the chest bone and illuminates the chest area. In this way, the surgeon can examine lymph nodes for abnormalities, check to see how far disease may have progressed and when necessary help diagnose lung cancer vs. mesothelioma.
Diagnosing mesothelioma is never easy. Fluid build up alone in the chest, belly or heart regions is not enough to confirm a diagnosis. Tissue samples obtained from biopsy procedures are also difficult to discern because mesothelioma cancer cells often resemble other types of cancer. For this reason, specialized laboratory procedures are often employed to identify certain chemicals that are known to exist with mesothelioma and high powered laboratory equipment is used to examine the smallest details of cancer cells to confirm that mesothelioma is present.
