Dry stools every day can be a clinical manifestation of colon cancer, often due to lesions in the colon caused by the invasion of cancer. Sometimes, it is caused by cancerous bowel obstruction. In addition to dry stools, some patients may also experience nausea, vomiting, abdominal distension, abdominal pain, and constipation. However, daily dry stools are not solely caused by colon cancer; some benign intestinal diseases can also lead to this condition, such as chronic constipation or melanosis coli, where patients may experience daily hard stools. Moreover, if dry stools occur daily and persist over a long period, they can potentially lead to malignant changes. Therefore, patients with daily dry stools should regularly undergo colonoscopy to prevent any pathological changes that might have progressed to cancer. Prompt treatment should be administered if the condition worsens.
