Abstract:
In the United States the incidence of carcinoma of the colon or rectum appears to be increasing. Although certain dietary habits appear to be associated with disease incidence, the putative carcinogens in the lumen of the bowel remain unidentified. The use of clinical screening based on a combination of proctosigmoidoscopy and tests for occult fecal blood allows detection of colorectal carcinomas at an early stage; however, it is unclear whether such screening is cost-effective in persons over 40 years of age or if treatment undertaken on the basis of screening results truly alters the natural history of the disease. Surgical resection is the mainstay of curative therapy, and its effectiveness will probably be enhanced by adjuvant x-ray therapy and chemotherapy.

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...
