"Could painless rectal bleeding be a sign of colorectal cancer?"

Painless hematochezia in stool does not necessarily indicate colorectal cancer, but may also be caused by other diseases. If this occurs, patients are advised to seek medical attention promptly for examination and treatment. Painless hematochezia in stool can be triggered by improper diet, such as excessive consumption of spicy or irritating foods or alcohol. It may also be caused by conditions like hemorrhoids or anal fissures. These situations generally do not have a significant impact on health or lead to serious consequences. There is no need for excessive concern or special treatment. Maintaining a healthy diet by avoiding spicy and irritating foods is recommended.

Colorectal cancer refers to malignant tumors that occur in the rectum and colon, often accompanied by symptoms like abdominal pain, diarrhea, constipation, and also painless hematochezia if the condition is severe. In such cases, relevant medical examinations such as abdominal CT and colonoscopy can be performed at a hospital. Following a definitive diagnosis, surgical resection of the affected area may be performed under the guidance of a physician. Postoperative radiotherapy and chemotherapy may also be required as adjunctive therapies. In daily life, it is important to maintain a balanced diet, focusing on light and easily digestible foods. Eating fresh fruits, vegetables, and foods rich in high-quality protein can help replenish essential nutrients. Additionally, ensuring adequate rest and avoiding late nights is crucial for overall health.
