Cardia cancer is at the gastroesophageal junction, which is a cancer at the top of the stomach and at the lower part of the esophagus, often caused by conditions such as gastroesophageal reflux and atrophic gastritis. Therefore, early stages of the disease may be accompanied by symptoms such as obstruction to eating, vomiting of blood and weakness and dizziness, and weight loss.

If patients have the above mentioned conditions, they should go to hospital immediately and let professional doctors diagnose through barium X-ray or endoscopy, and make a good differentiation with gastric cancer or esophageal cancer. If diagnosed, when the tumor diameter is less than 1 cm and there is no metastasis, endoscopic treatment with endoscopic debulking can be chosen. If the overall condition is good and there is no major cardiopulmonary comorbidity, surgery can be chosen. Patients with intermediate and advanced stage can choose radiotherapy, chemotherapy, palliative treatment, etc. In daily life, patients should have a balanced diet and avoid spicy and stimulating foods such as hot and sour noodles and fried chicken, as well as adequate rest and soothing mood to promote physical recovery.
