年轻人的大肠癌与中老年人相比,有以下几点不同。一是癌肿一左一右。在中老年大肠癌患者中,七成人发生在左侧直肠、乙状结肠和降结肠处;而青年人的大肠癌大多位于右侧的盲肠、升结肠处。二是腹痛一轻一重。中老年人的脏器因老化退化,对疼痛的敏感度降低,出现腹痛较轻或多为隐隐作痛。青年人患大肠癌后,病情进展较快,癌灶容易浸润到浆膜层,或病变引起炎症,出现剧烈腹痛。
The colorectal cancer among young people is different from that of middle-aged and old people. The first one is cancer left and right. Among the elderly patients with colorectal cancer, seven adults are found in the left rectum, sigmoid colon, and descending colon. The colorectal cancer in young people is mostly located in the right cecum and ascending colon. Second, abdominal pain is light and heavy. The organs of the middle-aged and elderly people are degraded due to aging, their sensitivity to pain is reduced, abdominal pain is lighter or they are more or less aching. After the young people develop colorectal cancer, the disease progresses rapidly, the cancer lesions easily infiltrate into the serosa, or the lesions cause inflammation and severe abdominal pain.
