There are no so-called 10 signs of bowel cancer in its early stages, which is an unscientific statement and not true. Bowel cancer patients usually have no obvious clinical symptoms in the early stage, but some patients will have signs such as change of bowel habit and change of fecal character in the early stage of bowel cancer. However, they are not typical and cannot judge whether they are suffering from bowel cancer accordingly. 1. Change of defecation habit: some patients in the early stage of bowel cancer will have signs such as increased frequency of defecation, constipation, diarrhea, etc., which are recurrent and not easy to be corrected. 2. Change of fecal character: in the early stage of bowel cancer, patients may have signs such as blood in stool, incomplete defecation, mucus stool and so on. Relying on signs and manifestations alone cannot diagnose bowel cancer. It is recommended that people with family history of gastrointestinal cancer should have regular physical examination, gastrointestinal microscopy and relevant tumor sensitivity indexes, etc. If there is any discomfort in the body, go to regular hospitals in time to improve the corresponding examination and make a clear diagnosis. Early prevention, early diagnosis and early treatment.
