Some work locally, like vitamin E in the colon, while other work more globally like selenium and vitamin C. Vitamin A appears to work by keeping cells differentiated which slows the growth rate.

Yet, the exact mechanisms by which these factors and their interplay predispose normal cells to a microenvironment that favors premalignancy and results in cancerized fields, remain to be investigated. ; Nadauld, L.D.

As a consequence of increased survival rates, surveillance and management of extracolonic malignancies should be included in the patient follow-up [, The APC gene was first discovered in the 1970s, and, in the following years, follow-up studies deeply analyzed its structure and function [, Moreover, APC also acts as a checkpoint protein in regulating the step from the G0/G1 to the S phase of the cell cycle. ; Prescott, S.M. Derived single-cell signatures were leveraged to characterize of precise transcriptional patterns that could help define a panel of markers for the early detection of gastric cancer (10). For more information, please refer to ; Dampier, C.H. By interrogating both the mutagenized epithelium and its microenvironment, we surmise that single-cellguided studies will help chart the spatiotemporal molecular and cellular atlas of field carcinogenesis, will further delineate preneoplastic initiation and progression, and will help identify cancer prevention and early intervention targets. Front Oncol. More recently, the selective advantage of an epithelial phenotype induced by field carcinogenesis drivers (e.g., TP53 mutations) was shown to be the product of an interplay between mutant epithelial cells and the surrounding microenvironment (1). Differential molecular interactions of beta-catenin and plakoglobin in adhesion, signaling and cancer. This new discipline, by precisely identifying the molecular basis of the differences between normal and malignant cells, has created novel opportunities and provided the means to specifically target these modified genes.

WebAbstract This study aimed to explore the biological functions and underlying mechanism of circRNA acetyl-CoA carboxylase alpha (circACACA) in colorectal cancer (CRC). We also highlight gaps in our knowledge of the molecular and cellular heterogeneity of field carcinogenesis and propose directions to tackle these voids using single-cellbased approaches and unique tissue sampling models.

So the more fiber you eat, the less risk you have of developing colon cancer. Patients affected will inevitably undergo abdominal surgery due to the malignant transformation of one or more adenomas.
