Cardia tumors are divided into benign and malignant tumors, and the final diagnosis relies on the pathological results of biopsy, such as smooth muscle tumors are benign tumors, but benign tumors of the cardia are relatively rare, so cardia tumors generally refer to malignant tumors, which is cardia cancer. Benign tumors can be cured by surgical resection. The main manifestations of cardia cancer are progressive dysphagia, vomiting mucus, and patients may experience wasting and weakness, and its diagnosis mainly relies on gastrointestinal imaging, gastroscopy and pathological examination. Surgery is the main treatment for cardia cancer. For patients who cannot be removed surgically, radiotherapy and chemotherapy can be chosen. If the patient is older and in poor general condition and cannot tolerate radiotherapy and chemotherapy, the treatment can be achieved by using Chinese medicine to identify and treat the evidence, to support and fight against cancer and to improve immunity.
