食管癌是常见的恶性肿癌之一。它严重地威胁着人们的生命和健康。我国每年约有16万人死于食管癌,占全部恶性肿瘤死亡人数的21.8%。临床上一般将食管癌分为早期、中期和晚期。从早期发展到晚期,有相当长的“带癌生存”时间,一般需要三年以上。这时身体的免疫功能与肿瘤处于相对平衡状态。若一旦有某些原因使身体的免疫功能受到损害,肿瘤的生长和扩散加快,迅速进入晚期阶段。此时再到医院就诊,多数已错过了良好的治疗机会,不久将会过早地离开人世,因为晚期食管癌平均自然生存期仅10个月左右。早期食管癌则截然不同,其五年以上生存率达90%以上,甚至可以完全治愈。因此,提倡早期发现、早期诊断和早期治疗。而“三早”的 Esophageal cancer is one of the common malignant tumors. It seriously threatens people’s lives and health. About 160,000 people die of esophageal cancer every year in China, accounting for 21.8% of all cancer deaths. Clinically, esophageal cancer is generally divided into early, middle and late stages. From the early stage of development to the late stage, there is a fairly long period of time with cancer survival, which generally takes more than three years. At this time, the body’s immune function is relatively balanced with the tumor. If the immune function of the body is impaired once for some reason, the growth and spread of the tumor is accelerated and it quickly enters the late stage. At this time, they went to the hospital for treatment. Most of them had missed a good opportunity for treatment and soon they would die. Because the average natural survival of advanced esophageal cancer is only about 10 months. Early esophageal cancer is very different, with more than 50% survival rate of more than 90%, and can even be completely cured. Therefore, early detection, early diagnosis and early treatment are advocated. And the “three mornings”
