Patients with tumor for the first time are mostly diagnosed in other clinical departments, such as lung cancer in thoracic surgery and respiratory medicine, and stomach cancer in gastroenterology and general surgery. If the patient’s condition is still in early stage, it is suggested that the patient should first go to surgery to find out whether surgery can be performed, because except for some tumors such as nasopharyngeal cancer and laryngeal cancer, most solid tumors, surgery has better effect; if the patient’s condition is nearly in the middle and late stage, radiotherapy and chemotherapy should be considered for comprehensive treatment, at this time, it is better for the patient to go to oncology specialist or oncology hospital, because it is difficult to achieve the best effect for solid tumors with simple chemotherapy or simple radiotherapy. So, how to determine the stage of patient’s disease? It is best to be done by oncologist or surgeon on the basis of full physical examination and adjuvant examination, so first time patients must not skip some necessary examination to save money, because tumor stage not only determines the prognosis, but also determines what kind of treatment you choose, or which kind of treatment is most suitable for you. Tumor patients are generally eager to seek treatment, but before treatment, they must choose the right department and specialty and learn more about it, so as not to take unnecessary detours for some reasons, which means wasting money and missing the good opportunity for treatment. There is no shortcut and no once-and-for-all method for tumor treatment. Don’t listen to rumors and believe in science and regular treatment.
