① Poststernal pain, which is more common when eating rough food, is acupuncture-like, burning-like or rubbing-like pain behind the sternum or under the xiphoid process, which can be relieved by taking antispasmodic agents. The pain site and lesion site of patients with esophageal cancer are often inconsistent.

② Early manifestations of esophageal cancer include foreign body sensation or food retention. Foreign body sensation is usually a slight feeling of tightness and bloating behind the sternum, which has no obvious relationship with eating, but may be intermittent or persistent, or occasionally food sticks to the esophageal wall when eating.

③ The main manifestations are progressive dysphagia, which eventually develops into difficulty in drinking water, even difficulty in passing saliva, food reflux, and chest and back pain. If cancer invades trachea and bronchus, it may form esophagotracheal fistula and/or esophagotracheal fistula, resulting in severe cough, dyspnea and pulmonary infection.

Esophageal cancer can still be treated in the early stage. For many years, the Chinese Medicine Esophageal Cancer Treatment Center of Henan Institute of Modern Medicine has been focusing on the research and treatment of esophageal cancer. The clinical treatment of tens of thousands of cancer patients by using the trinity therapy of esophageal cancer in traditional Chinese medicine proves that the total effective rate is over 97%. Studies have proved that traditional Chinese medicine can effectively prevent postoperative recurrence and metastasis of tumors; It can relieve and stabilize tumor focus, obviously improve clinical symptoms, improve the quality of life of patients, and many of them can be cured by taking traditional Chinese medicine. For patients with esophageal cancer treated in our hospital, it usually takes 3-7 days to take medicine quickly, and obvious effect can be achieved in10-15 days slowly, with symptoms improved and pain relieved. Taking1-2 courses can control the disease, and about 6 courses can achieve the purpose of rehabilitation, and it is not easy to relapse after rehabilitation. In addition, for patients in the middle and late stage or those who are not suitable for surgery, radiotherapy and chemotherapy, and those who relapse and metastasize after operation, the therapeutic purpose can be achieved.
