直腸癌是一个不太难诊断的疾病,较其他腸道肿瘤的早期发现,有着有利的条件,解剖部位低,容易检查,必要时还可以采取活组織送病理检查。根据統計絕大部分直腸癌可由肛诊測知。所以,只要临床医生提高对癌肿的警惕性,早期诊断直腸癌是不难的。但是,从一些文献上及平时临床工作中可以看到,它的延误诊断的情况还是相当严重的,有的可高达58.5%。 Rectal cancer is not difficult to diagnose disease, compared with the early detection of other intestinal tumors, has favorable conditions, low anatomical sites, easy to check, if necessary, can also take biopsy to send pathology. According to the statistics, the vast majority of rectal cancer can be detected by anal examination. So, as long as clinicians increase the vigilance of cancer, early diagnosis of rectal cancer is not difficult. However, from some literatures and clinical work at ordinary times, it can be seen that the delay in its diagnosis is still rather serious, with some up to 58.5%.
