Generally speaking, there is no self-test for lung cancer, but some patients can observe whether there are symptoms such as irritating cough, chest tightness, shortness of breath, dyspnea and hemoptysis in the early stage of the disease as a self-test for initially determining whether they are suffering from cancer. It should be noted that even if the patient has the above symptoms, it does not necessarily mean that it is caused by lung cancer, but may also be caused by other lung diseases, such as tuberculosis, pneumonia, lung abscess and so on.
People who want to know whether they are suffering from lung cancer are recommended to consult the doctor to improve chest X-ray examination, computed tomography scan, endoscopy, cytology examination and blood routine, tumor markers and other examinations to make a comprehensive judgment. Tissue cytology examination of suspected lesions can confirm the diagnosis.
