How Does Reducing Colonic Transit Time With Fiber Prevent Colorectal Cancer
Less contact: The hypothesis is that one factor in colon cancer is potentially ingested carcinogens(cancer causing) that are in the food we eat. The faster the stool moves through the colon, the less time the carcinogen has in contact with any segment of the colon so it's should be less damaging. ...Read moreSee 2 more doctor answers
Colorectal cancer is cancer of the colon or rectum. The cells lining the colon or rectum become abnormal and grow uncontrollably. They start as polyps. Symptoms include blood in the stool, constipation, loss of appetite, and weight loss. This cancer can be prevented through early screening, if a polyp is detected during a colonoscopy and excised. Additionally, a high fiber diet with plenty of water and a ...Read more
Genetic mutations: HNPCC or hereditary nonpolyposis colorectal cancer is an autosomal dominant genetic condition that has a high risk of colon cancer The disease first described by Lynch and is associated with other cancers including endometrial ovary and stomach. The increased risk is due to inherited mutations that impair DNA mismatch repair. .Individuals with HNPCC have an 80% lifetime risk for colon ca. ...Read more
Yes and no: Both are adenocarcinomas of the 'large intestine' broadly speaking. However, due to several anatomic differences, colon and rectal cancer behave differently. For that reason the preoperative staging is different and the treatment can be different (surgery +/-chemotherapy for colon cancer, surgery +/- chemoradiation therapy for rectal cancer). The functional outcomes are different as well. ...Read moreSee 1 more doctor answer

In that case, you might have frequent bms. ...Read moreSee 2 more doctor answers

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
