The precancerous colon cancer prevention

Should actively colorectal cancer prevention and treatment of precancerous lesions of the colon adenomatous polyposis, in particular the family of multiple polyposis colon should be removed early lesions, and to control schistosomiasis, dysentery, chronic ulcerative colitis and other intestinal inflammation. Attention to diet structure, to avoid高脂肪饮食, eating more fiber-rich foods, pay attention to maintaining open defecation. High-risk population of middle-aged and above regular fecal occult blood test, digital rectal and colon endoscopy attending the census, may be early detection of colorectal and colon cancer effective way.

Internal reports, confirmed by the Organization of the patients with colorectal cancer, without effective treatment, the natural course of an average of 9.5 months. The prognosis of the disease depends on early diagnosis and radical surgery. As early colorectal cancer and more asymptomatic, the majority of patients diagnosed, the session has been advanced, colorectal cancer after radical five-year survival rate was only 50.21 percent. Prognostic factors:

(1) of the cancer cell differentiation levels: low degree of differentiation, poor prognosis.

(2) age of onset: young patients poor prognosis than older patients.

(3) wall depth of invasion and lymph node metastasis: Early colorectal cancer who have lymph node metastasis, and poor prognosis.

(4): Colorectal week Drive extensive involvement, have had

Obstruction, 5-year survival rate generally only half of those without obstruction. There intestinal bleeding, perforation, purulent peritonitis, and other complications, poor prognosis.
