New way to tell mesothelioma from another lung cancer
Mesothelioma begins much like other lung diseases, but it becomes aggressive only in its later stages. Because early detection can make an important difference in how your doctor might treat you, it is critical to determine as early as possible whether a lung disease you have is malignant pleural mesothelioma or not.
Now, in addition to taking a history to determine your exposure to asbestos, doctors have a new way of finding out earlier whether a lung cancer might be mesothelioma as opposed to adenocarcinoma, another type of cancer that can attack in the same place—the lining of the lung—or may attack in other places but then reach into the lungs. They can send a tissue sample out for a relatively simple test. A company has developed a way to measure certain substances (biomarkers) that can tell the difference between mesothelioma and adenocarcinoma.
This offers hope that similar tests can be developed that will help determine whether, for example, pleurisy symptoms in your lungs and chest are actually from pleurisy or from another disease such as mesothelioma. The simpler and more precise the tests, the better more doctors will understand how to diagnose mesothelioma earlier–and make a difference to the patient’s quality of life and produce more longer-term mesothelioma survivors.
