If endometrial cancer has high-risk factors, chemotherapy is needed after surgery if these high-risk factors are found in the pathological staging. If it's early-stage endometrial cancer without these high-risk factors, chemotherapy might not be necessary after surgery because chemotherapy also serves to prevent recurrence and metastasis. Therefore, it is advised that patients with high-risk factors in endometrial cancer undergo chemotherapy. Although chemotherapy may have significant side effects, it can improve the survival time and quality of life for cancer patients. The decision to proceed with chemotherapy should be based on the postoperative pathological staging, biopsy results, and the presence or absence of factors like lymph node metastasis.
