Early cellular events in colorectal carcinogenesis

Abstract excerpt

Colorectal cancer develops through a multistage process recognizable at a histopathological level by progression from normal mucosa to invasive carcinoma (the adenoma-carcinoma sequence). For many years, it has been hypothesized that increased cell proliferation in the colonic crypt represents the earliest recognizable stage in this sequence. This perspective is now changing. While several human studies have...
