Abstract:
Patients with ulcerative colitis (UC) are at an increased risk for the development of colorectal cancer (CRC). Unlike sporadic CRC, the cancer in UC patients arises from a focal or multifocal dysplastic mucosa in areas of inflammation. The clinical features of UC-associated cancer are similar to those found in patients with hereditary non-polyposis colorectal cancer. As with other varieties of CRC, UC-associated cancer exhibits a variety of genetic and molecular changes/abnormalities. These abnormalities are however clustered in areas of mucosae with histological abnormalities. The magnitude and timing of these changes are however significantly different. Surveillance and identification of patients at risk for cancer are a challenging problem.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
