What are the common early symptoms of colorectal cancer patients

The early symptoms of colorectal cancer are generally not obvious, and only manifest as symptoms of precancerous lesions. However, as the lesions progress, a series of symptoms and signs may appear. Many patients may not know the early symptoms of colorectal cancer. The common early symptoms of colorectal cancer in clinical practice can be summarized as follows:

1. Blood in the stool: The surface of the tumor is different from the normal mucosa, and it is easy to bleed after friction with the stool. The stool in the lower large intestine is dry and hard, so blood in the stool is the most common early symptom of colorectal cancer. Because the lesion is close to the anus, the blood is mostly bright red or dark red, and the blood and stool are often separated. The stool in the right colon is still in a semi-fluid state, so the amount of bleeding in right colon cancer is relatively small. In addition, the color of the blood mixed in the stool changes, so it is not easy for patients to detect. Most of them are occult blood positive. Only when the amount of bleeding is large can the stool be seen to be brown and jam-like.

2. Anemia: When long-term chronic blood loss exceeds the body's hematopoietic compensatory function, the patient may develop anemia , an early symptom of colorectal cancer . Generally speaking, the later the disease is, the more frequent and severe the anemia is. Anemia is not necessarily a late manifestation. For example, 34.9% and 50.9% of patients with stage I and II colon cancer, respectively, had hemoglobin levels below 100g/L. 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.
