Precancerous conditions are characterized by an increased epidemiological cancer risk, precancerous lesions by a histopathological abnormality (epithelial dysplasia). Adenomas are typical examples of this in the GI tract and therefore must be removed by endoscopy or surgery. The extent of the procedure is dictated by size, growth pattern and histology. The Barrett oesophagus, chronic atrophic gastritis type B, colorectal adenomas and familial adenomatous polyposis are the most frequent serious conditions.
癌前状态的特征是癌症流行病学风险增加，癌前病变则具有组织病理学异常（上皮发育异常）。腺瘤是胃肠道中此类病变的典型例子，因此必须通过内镜检查或手术切除。手术范围取决于大小、生长方式和组织学类型。巴雷特食管、B型慢性萎缩性胃炎、结直肠腺瘤和家族性腺瘤性息肉病是最常见的严重情况。
