How is mesothelioma diagnosed?
Through careful examination, doctors can diagnosis patients as having a form of cancer caused by asbestos which is known as mesothelioma. There are different tests doctors use in conjunction with one another to suggest a mesothelioma diagnosis. However, the most convincing is a biopsy of the tissue.
Doctors may recommend other tests to provide them with more information as they proceed to create a treatment plan. Some common tests would include X-rays, CT scans and MRIs. Some other tests are used such as cytology. This involves testing the pleural fluid for malignant cells. While this can provide some useful information, it is quite limited in making a diagnosis of mesothelioma. Many times when the fluid is tested the findings can be negative or inconclusive. Only 15% of the time are the results accurate.
Biopsies are the most conclusive way in which to determine a mesothelioma diagnosis. One of these is a simple needle biopsy which is done under a local anesthesia. Tissue samples are collected by using a needle. Even this type of biopsy is limited. The sample taken is rather small which in some situations is not large enough to make a confident diagnosis. The more effective biopsy method is an open biopsy. This procedure provides a much larger tissue sample. Given this fact, this procedure must be done in an operating room under general anesthesia.
