If it is early stage bowel cancer, the 5-year survival rate is about 90%, and if it is advanced stage bowel cancer, the 5-year survival rate is less than 10%. The main factors of the impact of bowel cancer on life need to be based on whether early detection, pathological tissue typing, and also related to patient’s physical health condition, clinical symptoms and disease progress. 1.In the early stage of bowel cancer, there are usually no clinical symptoms or symptoms are not obvious, only symptoms such as indigestion and fecal occult blood, etc. With the aggravation of symptoms, it is manifested as change of stool habit, blood in stool, intestinal obstruction, abdominal mass, etc. The early diagnosis and early treatment, the greater the possibility of patient’s recovery. The pathological types of bowel cancer include papillary adenocarcinoma, tubular adenocarcinoma, mucinous adenocarcinoma, squamous cell carcinoma, indolent cell carcinoma, squamous cell carcinoma, adenosquamous carcinoma and undifferentiated carcinoma, etc. Among them, mucinous adenocarcinoma and undifferentiated carcinoma are more malignant and have poor prognosis, which have a greater impact on the survival of patients. 3. The health condition of bowel cancer patients is also related to nutrition and mental and psychological factors. Keeping a relaxed mood and eating more foods with high vitamin and protein are conducive to disease recovery. Therefore, early detection and early treatment of bowel cancer play a key role in the treatment of the disease. Paying attention to dietary hygiene and not eating cold and spicy food in general also play a role in the prevention of bowel cancer.
