Whether the cardia lesion is serious or not mainly depends on the nature of the lesion, if it is inflammatory infection or benign tumor, it is usually not serious, if it is malignant tumor it is more serious. There are many types of cardia lesions, among which the more common ones are carditis, benign cardia tumor and cardia cancer. In case of carditis or benign cardia tumor, most of them are not serious and can be treated with acid-suppressing and stomach-protecting therapy such as omeprazole and thioglycollate or surgically removed. Drugs should be used under the guidance of doctor. However, if cardia cancer is more serious, early and early treatment is possible to cure it, but if it is found late, it is often not possible to take radical treatment, and it may even be dangerous to life. The lesions of cardia need to go to the hospital in time to find out the cause and then take targeted treatment, and if it is cardia cancer, go to the hospital for rechecking regularly after treatment.
