Early Symptoms of Sigmoid Colon Cancer
A friend of mine has recently noticed an increased frequency of bowel movements, accompanied by abdominal pain, bloating, and fatigue. He suspects he may have sigmoid colon cancer—what are the early symptoms of this condition?
Early Symptoms of Sigmoid Colon Cancer
In its early stages, sigmoid colon cancer may present with abnormal bowel habits and bloody stools. Some patients experience frequent bowel movements; others feel a persistent sensation of incomplete evacuation; some pass purulent stools; and in certain cases, overt rectal bleeding occurs. Additional symptoms may include abdominal pain, bloating, unintentional weight loss, and fatigue. Patients exhibiting these signs should seek prompt evaluation at a reputable hospital. Comprehensive preoperative assessment and preparation are essential, followed by timely surgical intervention—specifically, radical resection of the sigmoid colon tumor.

Treatment for sigmoid colon cancer depends on the disease stage. For early-stage tumors, radical surgical resection remains the optimal therapeutic approach. However, if high-risk features such as regional lymph node metastasis, vascular tumor thrombi, or perineural invasion are present, adjuvant chemotherapy following surgery is recommended.

Patients are advised to adopt healthy lifestyle and dietary habits, avoiding raw, cold, or spicy foods whenever possible. We hope this information proves helpful.
