Symptoms of colorectal cancer

The symptoms of rectal cancer include rectal irritation symptoms, bleeding symptoms, intestinal stenosis symptoms, etc.

1. Rectal irritation symptoms

are a series of symptoms caused by the stimulation of the rectum by the lesion site in most cases, including changes in defecation habits, frequent defecation, anal drop feeling before defecation, urgency after defecation, and abdominal pain in the late stage.

2. Bleeding symptoms The

tumor tissue is relatively fragile, and when feces pass, it often leads to bloody stools.

3. Intestinal stenosis Symptoms When the

tumor further develops and leads to intestinal stenosis, the stool will become thin at first, and the later stage will be dominated by incomplete intestinal obstruction such as bowel sounds and abdominal distension.
