Gastric intramucosal cancer cannot be 100% cured. Gastric intramucosal cancer mainly refers to gastric carcinoma in situ, which is also early gastric cancer, and can be completely removed by surgery, but for the tumor, even after radical resection, there will still be some tumor cells left in the blood, and the patients have serious susceptibility, which will easily cause recurrence or metastasis of the tumor when the patients’ resistance is poor and their diets are not regular, so gastric intramucosal cancer can not be cured 100%. Besides, for patients with gastric endomucosal cancer after resection, gastroenteroscopy should be checked regularly so that early detection and early treatment can be achieved to avoid delaying the condition due to the lack of regular checkups. For patients with gastric endomucosal cancer, they should relax their mood, a good mood can reduce the possibility of recurrence of the disease.
