Colorectal cancer (CRC) which is diagnosed in patients under the age of 50 years is defined as young-onset CRC. There has been a substantial increase in the incidence and mortality of young-onset CRC in the past four decades and the patients have delayed diagnoses leading to the advanced stages of CRC at the time of diagnosis. Here we present a case of a 34-year-old male patient with colon cancer and a literature review on young-onset colon cancer to highlight the age-related disparities in CRC incidence and try to explore the possible causative factors for the rise in incidence and mortality in young patients due to CRC.
50岁以下患者被诊断出的结直肠癌（CRC）被定义为青年型结直肠癌。在过去四十年中，青年型结直肠癌的发病率和死亡率大幅上升，且患者诊断延迟，导致诊断时已处于结直肠癌晚期。在此，我们展示一例34岁结肠癌男性患者的病例，并对青年型结肠癌进行文献综述，以突出结直肠癌发病率与年龄相关的差异，并试图探讨青年患者因结直肠癌导致发病率和死亡率上升的可能致病因素。
