What are the early symptoms of colorectal cancer ? The specific early symptoms of colorectal cancer are introduced as follows:

Red blood cells can be found in stool microscopy, and the stool occult blood test is positive;

2. Changes in bowel habits are one of the early symptoms of colorectal cancer: the frequency of bowel movements changes from once a day to two or three times a day, and there is a feeling of incomplete bowel movement after each bowel movement;

3. Abdominal pain and bloating: Intestinal cancer patients may experience abdominal bloating and pain due to intestinal obstruction, which are early symptoms of intestinal cancer. The incidence of abdominal pain is higher than that of bloating. The pain is mostly in the middle and lower abdomen, and the severity varies. The early symptoms of intestinal cancer are mostly dull pain or bloating;

4. Mucus and bloody stools: When the tumor ruptures, the stool often contains bright red or dark red blood and mucus. The early symptoms of intestinal cancer may be mixed with blood in the stool.

5. Anemia and weight loss: As the disease progresses, patients may develop early symptoms of chronic wasting colorectal cancer and even cachexia, often accompanied by fatigue and unexplained weight loss, which is related to bloody stools, insufficient intake and excessive consumption.
