Dr. Shen Yonghua
The early symptoms and signs of colorectal cancer are often not obvious and can be easily overlooked. The most common manifestations include changes in bowel habits, such as alternating diarrhea and constipation, or a narrowing of the stool. Abdominal discomfort, cramping, or bloating may also occur. A persistent sensation of incomplete evacuation after bowel movements, known as "tenesmus," can be present. Some patients may notice blood or mucus in the stool, accompanied by general symptoms such as significant weight loss and decreased appetite. In some cases, patients may feel fatigued or weak, often related to anemia. Early detection of colorectal cancer is crucial for effective treatment; therefore, persistent gastrointestinal symptoms should be taken seriously and medical attention sought promptly.
