Gastric cancer mainly occurs in middle-aged and older people after their 50s, and the incidence of gastric cancer in younger people is rare. The frequency of gastric cancer that occurred before 40 years of age is 6-8% of all gastric cancer patients, and most of them are over 35 years of age. The prognosis of gastric cancer in young patients is believed to be poor because of more aggressive tumor behaviors and delayed diagnosis, however, there is controversy.
胃癌主要发生在50岁及以上的中老年人中，年轻人患胃癌的情况较为罕见。40岁之前发生的胃癌病例占所有胃癌患者的6%-8%，其中大多数年龄超过35岁。由于肿瘤行为更具侵袭性以及诊断延迟，年轻患者的胃癌预后被认为较差，然而，这一点存在争议。
