Pain is one of the main manifestations of gastric cancer, and the pain will be more severe and last longer in advanced stage of gastric cancer. The survival time is mainly related to the patient’s age, physical condition, and the treatment method adopted. Although the advanced stage of gastric cancer is incurable, the survival time will be prolonged by choosing the appropriate treatment method to actively treat it. When patients have severe pain, they can choose pain-relieving drugs symptomatically, and if other complications appear, they should actively cooperate with the doctor for treatment. The survival time will be prolonged to several years or even a dozen years if you do a good job of prevention and keep your mood happy, optimistic and positive.
