Dry, granular stools are not necessarily symptoms of colon cancer, but patients with colon cancer may also experience dry, granular stools. Therefore, after exhibiting the above symptoms, patients need to promptly complete an electronic colonoscopy to confirm the diagnosis of the disease. For example, if the symptoms are due to colon cancer, aggressive surgical treatment should be taken, followed by comprehensive treatment including radiotherapy and chemotherapy. If the symptoms are due to functional indigestion causing constipation, treatment should involve using medications to regulate the intestinal flora and relieve constipation.
