1. Symptoms caused by cancer bleeding

Anemia: A symptom of colorectal cancer When long-term chronic blood loss exceeds the body's hematopoietic compensatory function, colorectal cancer patients may develop anemia. Generally speaking, the later the disease is, the more frequent and severe the anemia is. In particular, right-sided colon cancer often presents anemia as the first symptom, so clinicians must not give up active surgical treatment simply because of anemia.

2. Symptoms caused by tumor obstruction

When the tumor grows to a considerable size or infiltrates the intestinal wall muscle layer, it can cause intestinal stenosis, the intestinal cavity becomes smaller, and the passage of intestinal contents is blocked. At this time, symptoms such as bowel sounds, abdominal pain, abdominal distension, constipation, and difficulty in defecation may occur. When the lesion is located in the rectum, the stool may become deformed and thin, and it may be difficult to defecate all at once. The frequency of bowel movements may increase or there may be a feeling of tenesmus. Further development may lead to partial or even complete intestinal obstruction, which is also a symptom of colorectal cancer.

I hope that after everyone understands the specific symptoms of colorectal cancer, they will no longer make the mistake of ignoring the symptoms of colorectal cancer, which will increase the harm of colorectal cancer.
