Cases of esophageal cancer are often admitted to oncological establishments at relatively late stages of tumor process: in 85%, the record of symptoms exceeds three months. The average duration of case histories before admission is 7.4 months. Diagnostic errors were established in the patients who had consulted the doctor during a period of less than 3 months after symptom development. This was due to the frequent appearance (41%) at initial stages of symptoms other than dysphagia which was misleading. However, even if dysphagia was apparent, primary X-ray examination failed to detect esophageal tumors in 20.1% of cases. Therefore, an endoscopic examination must be performed in cases of dysphagia. Whenever dysphagia is a consequence of esophageal burns, patients should undergo examinations at specialized oncological establishments for some years.
85%的病例症状记录超过三个月。入院前病历的平均时长为7.4个月。在症状出现后不到3个月就咨询医生的患者中发现了诊断错误。这是因为在初始阶段经常出现（41%）吞咽困难以外的症状，这些症状具有误导性。然而，即使吞咽困难明显，初次X线检查仍有20.1%的病例未能检测出食管肿瘤。因此，出现吞咽困难的病例必须进行内镜检查。只要吞咽困难是食管烧伤的结果，患者就应在专业肿瘤专科医院接受数年的检查。
