Colorectal cancer has a prevalence of 7% at 30 years after diagnosis and accounts for 15% of deaths in people with Crohn's. Risk is higher if the disease occurs in most of the colon. Risk is higher if the disease occurs in most of the colon.
People with inflammatory bowel disease (ulcerative colitis and Crohn's disease) are at increased risk of colon cancer. [31] [32] The risk increases the longer a person has the disease, and the worse the severity of inflammation. [33] In these high risk groups, both prevention with aspirin and regular colonoscopies are recommended. [34]
Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine, with Crohn's disease and ulcerative colitis (UC) being the principal types. [3] Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas UC primarily affects the colon ...
Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary predisposition to colon cancer.. HNPCC includes (and was once synonymous with) [1] Lynch syndrome, an autosomal dominant genetic condition that is associated with a high risk of colon cancer, endometrial cancer (second most common), ovary, stomach, small intestine, hepatobiliary tract, upper urinary tract, brain, and skin.

Colorectal cancer is a disease of old age. It typically originates in the secretory cells lining the gut, and risk factors include diets low in vegetable fibre and high in fat. If a younger person gets such a cancer, it is often associated with hereditary syndromes like Peutz-Jegher's, hereditary nonpolyposis colorectal cancer, or familial ...
Gross pathology of normal colon (left) and severe ulcerative colitis (right), forming pseudopolyps (smaller than the cobblestoning typically seen in Crohn's disease), over a continuous area (rather than skip lesions of Crohn's disease), and with a relatively gradual transition from normal colon (while Crohn's is typically more abrupt).
The Crohn's Disease Activity Index or CDAI is a research tool used to quantify the symptoms of patients with Crohn's disease.This is of useful importance in research studies done on medications used to treat Crohn's disease; most major studies on newer medications use the CDAI in order to define response or remission of disease.
A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
