SCREENING AND MANAGEMENT OF EARLY CANCER COLON

Incidence of cancer colon increase with increasing socioeconomic status. Diets high in meat and fat, low in fruit and vegetables are associated with an increased risk of colorectal cancer. A number of groups have an increased risk of developing colorectal cancer. At highest risk are those with either of the dominantly inherited conditions familial adenomatous polyposis (FAP) and heridetary non polyposis colorectal cancer (HNPCC).Most colorectal cancer arises in adenomatous polyps and their ablation arrests the development of cancer. Other groups at moderately increased risk include those with long standing ulcerative colitis or Crohn’s disease.Early detection of colorectal cancer is actually prevented by detection and removal of adenomatous polyps.History in a case of carcinoma of the colon or rectum may sometimes prove unhelpful in reaching a diagnosis, or actually misleading. Colorectal cancers remain asymptomatic for years; symptoms develop insidiously and frequently have been present for months, sometimes years, before diagnosis.
