Colorectal carcinoma is the second most common cause of death in Canada. Because there is a precursor lesion (that is, the polyp), screening is critically important to prevent the disease through polyp removal-and failing that, to detect colorectal carcinoma at an early stage, when it can be cured. Several screening modalities are available, but colonoscopy is considered the best. People should avail themselves of such examinations, and physicians should encourage them to do so.
结直肠癌是加拿大第二大常见死因。由于存在前体病变(即息肉),因此通过息肉切除来预防疾病,或者在无法切除时早期发现结直肠癌非常重要,因为此时癌症可以治愈。有几种筛查方法,但结肠镜检查被认为是最佳方法。人们应该接受这些检查,医生也应该鼓励他们这样做。
