It is possible for a patient with bowel cancer to have no change in blood count, which means that the test is normal. There may also be changes, such as more anemia, and there may be a decrease in white blood cells and a decrease in platelets in the course of doing treatment. Bowel cancer may show more blood in the stool, and if there is long-term chronic blood loss, it will show lower hemoglobin and lower red blood cells in the blood routine. If it is an early stage of intestinal cancer and there is no obvious blood in stool or the blood in stool is not serious, this condition may not show any change in blood routine. The development of bowel cancer or the diagnosis of bowel cancer cannot be based on whether there is a change in blood count alone. Bowel cancer is a kind of malignant tumor of digestive system, which is mainly treated by surgery after detection and can be combined with radiotherapy and chemotherapy after surgery.
