The presence of leg swelling in cervical cancer patients is not necessarily a precursor of death. There are many signs and symptoms of precursor of death, which cannot be determined by leg swelling alone; patients need to make a comprehensive assessment and judgment. Patients with leg swelling can be seen in the following situations: 1) patients with abdominal lymph node metastasis may have leg swelling in the lower limbs; 2) patients may have hypoproteinemia and leg swelling may also occur; 3) patients with venous thrombosis may also have leg swelling. A clear diagnosis should be made and treatment should be given for the cause. At the same time, pay attention to more rest, eat high-protein food to supplement nutrition, avoid spicy and stimulating food, adjust the mentality and maintain optimism.
