The ten signs of bowel cancer in women are a little bit absolute. Signs of bowel cancer include precancerous lesions and early symptoms, such as irregular bowel movements, bowel polyps and other precancerous lesions. 1. Pre-cancerous lesions: Bowel cancer is often associated with colon polyps, ulcerative colitis, schistosomiasis granulomatosis and family history, etc. 2. Early clinical manifestations of bowel cancer: according to different tumor lesions, early manifestations are also different. For example, the right half of colon has a large intestinal lumen, and the right colon cancer of bulging type is common, which is easy to be necrotic, bleeding and infected, therefore, abdominal pain, abdominal mass and systemic symptoms are the main symptoms; the intestinal lumen of the descending colon is small, and the infiltration type of colon cancer of the left colon is common, which is easy to cause narrowing of intestinal lumen and obstruction, therefore, the symptoms of obstruction, change of defecation habits and stool properties are the main symptoms. Bowel cancer is also related to dietary intake of excessive fat and protein, lack of dietary fiber, age, obesity, ethnicity, smoking and other factors. Therefore, people with high risk factors for bowel cancer should be checked regularly for bowel cancer.
