Patient's question:
Five years ago, I had surgery for rectal cancer. This year, it was found that the cancer has metastasized to the pelvis, with a tumor size of 3 centimeters. How should pelvic cancer be treated?Doctor's answer:
Clinically, radiotherapy is one of the more effective local treatment methods for treating pelvic cancer, especially malignant tumors. Although radiotherapy shows rapid results, it is also difficult to completely eliminate all cancer cells. Additionally, while killing cancer cells, some normal body tissue cells are inevitably "shot down" as well. Therefore, radiotherapy can produce strong toxic side effects on the patient's body, causing great suffering. As a result, radiotherapy should not be frequently used for treating tumor patients.
