Dr. Shen Yonghua
Common symptoms that may appear in the early stages of colorectal cancer:
1. Changes in bowel habits: Persistent constipation, diarrhea, or narrowing of the stool may be early signs of colorectal cancer. These changes should be taken seriously if they persist for more than a few weeks.
2. Blood in the stool: Painless rectal bleeding or presence of bright red or dark red blood in the stool.
3. Abdominal pain or discomfort: Unexplained abdominal pain, bloating, or discomfort, especially after eating.
4. Weight loss: Unintentional weight loss, particularly when accompanied by the aforementioned symptoms.
5. Fatigue and anemia: Colorectal cancer may cause chronic blood loss, leading to anemia, which manifests as persistent fatigue, pallor, and shortness of breath.
6. Abdominal mass: A firm lump felt upon touching the abdomen may be a sign of a tumor.
If any one or more of the above symptoms occur and persist, prompt medical attention is advised.
