Malignant Mesothelioma will typically be suspected if the patient complains of chest pain, difficulty breathing, shortness of breath, chronic cough, or difficulty swallowing. While any of these could indicate mesothelioma, they are also associated with many other respiratory conditions so further diagnostic procedures are typically warranted before an accurate malignant mesothelioma diagnosis can be made. These may include imaging scans, such as computer topography or magnetic resonance imaging. A diagnostic biopsy is also required for cancer specialist to examine the behavior of these cells before a diagnosis is determined.
Misdiagnosis is not uncommon in patients of the malignant mesothelioma, because the disease's symptoms so closely resemble those of other related conditions, including lung cancer, and other respiratory ailments. For this reason those who are at high-risk of mesothelioma (including those with asbestos history) should consult with physicians and cancer centers well versed in the treatment and diagnosis of malignant mesothelioma.
