This is a common mistake made by more than 60% of patients, and the consequences are still not small! Today, I would like to give a brief account of this for the families of patients who patronize this science article, in the hope that it can give some help to the bewildered patients who seek medical care! I hope it can help the bewildered patients! I feel the words of one of my post-surgery patients’ family members: good instructional articles can save lives! Lung cancer esophageal cancer or tumor of the lung esophagus should see surgery first, do not make the mistake of seeing internal medicine if the lung and esophagus grow inside the body, if the patient who should be open to surgery mistakenly enters the internal medicine hospital, the wasted time and cost are not conducive to the consultation! By the time you transfer to surgery again, the time may be 7-10 days already and the cost is spent a lot! It affects the timely treatment! But you see the surgery first, should not be operated on in the provincial hospital will not admit you, because the need for open surgery are lining up beds. Surgery is a subject of modern medicine that focuses on how to use surgical methods to relieve patients of their pathogens so that they can be treated. Esophageal cancer’ lung cancer or esophageal tumor surgery is the preferred treatment because it can remove the root cause, internal medicine is the treatment discipline that can be completed by conservative treatment with drugs alone, of course, in recent years, internal medicine doctors have also started to innovate some interventional operations such as radiofrequency, particle implantation, etc. for patients with in situ precancerous lesions or those who cannot be operated on. However, they are not complete radical treatment methods, most of them are treatment options of last resort with limiting factors, but some precancerous lesions in situ have some effect! For this reason, family members of patients with lung and esophageal masses, tumors, blood in the sputum, irritating cough, choking on food, inability to swallow, please consult the thoracic surgery department first!
