It is not a bad idea to have a second opinion. Usually the first physician an individual visits is the family doctor and it is very difficult that he/she is an expert in the field of mesothelioma. Remember also that mesothelioma is a rare disease and even some oncologists (physicians that treat cancer) may not have any experience in the treating of mesothelioma. Therefore it is important to ask for a second opinion preferably at a mesothelioma centre. Your physician may help you to find a mesothelioma expert. It is also important to check if your health insurance policy covers this for you since this may not always be the case.
