Peritoneal mesothelioma, like the other forms of mesothelioma, shows a very long latency period and it wont be until 20-30 years since the asbestos-exposure days before any typical symptoms becomes apparent. But by then it will be too late to check the disease or provide any constructive medication or treatment. Further, a delay in diagnosing the disease can happen due to the fact that most of the symptoms of mesothelioma is not-specific and may resemble that of some other common and less serious diseases. For example, the common mesothelioma symptoms include anemia, fever, weight loss, abdominal pain, and bowel obstruction, and it is highly likely that the doctor initially may consider other options than contemplating cancer. Therefore, the patient telling the doctor about any previous asbestos exposure in the first one-to-one interaction itself is very crucial, and that helps the doctor to think of a possible mesothelioma threat even before considering other possibilities.
