Can colon cancer be cured by removing a malignant tumor?

Whether or not a malignant colorectal cancer tumor can be cured after resection depends on many factors, including tumor stage, patient's physical condition and treatment effect. Early detection and timely surgical resection have a higher cure rate; even if advanced tumors are resected, the risk of recurrence still exists.

1. Tumor staging is the key to determining the cure rate. Early stage I and II colorectal cancer tumors are confined to the intestinal wall and have not spread to the lymph nodes or other organs. The cure rate can reach more than 80% after surgical resection. Stage III colorectal cancer tumors have spread to the lymph nodes and require chemotherapy after surgery. The cure rate is about 50%-60%. Stage IV colorectal cancer tumors have metastasized to other organs. Even with surgical resection, the cure rate is low, and the treatment goal is more to prolong survival and improve quality of life.

2. The patient's physical condition affects the treatment effect. Young patients with better physical fitness have a stronger tolerance to surgery and chemotherapy and a better treatment effect. Patients with other chronic diseases such as diabetes and hypertension have a slower recovery after surgery, which may affect the overall treatment effect.

3. The treatment effect is closely related to postoperative management. Regular postoperative review and follow-up are the key to preventing recurrence. Review items include colonoscopy, tumor marker detection and imaging examination. Postoperative chemotherapy can kill residual cancer cells and reduce the risk of recurrence. Targeted therapy and immunotherapy provide new treatment options for patients with advanced colorectal cancer.

After the removal of the malignant tumor of colorectal cancer, the patient needs to actively cooperate with postoperative treatment and management. Early detection and early treatment are the key to improving the cure rate. Regular postoperative follow-up, a reasonable diet and moderate exercise can help reduce the risk of recurrence and improve the quality of life. Even for advanced colorectal cancer, comprehensive treatment can effectively prolong survival.
