There is no fixed answer to the question of how long cardia cancer can survive after surgery, but it depends on the characteristics of the tumor, the stage at the time of diagnosis, comprehensive treatment and even the patient’s own cooperation. If cardia cancer is detected early and radical surgery is performed as soon as possible, and a reasonable chemotherapy and radiotherapy plan is chosen according to the type of cancer, and there is positive and optimistic mental state, reasonable diet and good lifestyle, it is a guarantee of long-term healthy survival after surgery. This makes long-term survival possible. Cardia cancer is a kind of malignant tumor, suffering from this disease will bring great impact on health and needs active measures for diagnosis and treatment, which is related to dietary factors, environmental factors, genetic factors and Helicobacter pylori infection. There are also precancerous changes such as chronic atrophic gastritis, gastric ulcer, gastric polyp, gastric mucosal epithelial cell metaplasia and gastric mucosal epithelial heterotypic hyperplasia. Cardia cancer must be treated early so as not to delay the treatment and bring harm to one’s health. Although theoretically and clinically, malignant tumors are difficult to be cured and the prognosis is closely related to the stage of the tumor, early treatment has good effect, small recurrence rate and can lead to long-term survival. At present, multidisciplinary and comprehensive research on cardia cancer is conducted in China, which will greatly improve its early diagnosis and treatment as well as the five-year survival rate of patients after surgery in the future.
