Postoperative lymphedema after cervical cancer surgery may be caused by cutting off lymphatic vessels or postoperative complications, which can be eliminated by elevating the lower limbs. It may also be caused by metastasis of cervical cancer cells blocking lymphatic vessels, which needs surgery. 1. Lymphatic vessels are cut off: in cervical cancer surgery, if the lymphatic vessels are removed together, it may lead to postoperative lymphedema, patients can reduce the activities and elevate the lower limbs appropriately to relieve the lymphedema. 2. Postoperative complications: A common complication of cervical cancer surgery is local soft tissue lymphedema, patients can elevate the lower limbs, ensure sufficient nutrition, and follow up regularly for observation, after lymphatic drainage side branch path is established, lymphedema can be relieved to a certain extent. 2. Metastasis of cancer cells: if metastasis occurs after surgery for cervical cancer, cancer cells may block lymphatic vessels and cause lymphoedema due to poor return of lymphatic fluid, in this case, patients may need second surgery to reduce lymphoedema. If lymphedema occurs after cervical cancer surgery, patients can reduce activities and elevate the lower limbs to relieve it. If it cannot be relieved or the lymphedema worsens progressively, patients need to go to the hospital in time to clarify the cause of lymphedema, and then take further treatments under the guidance of doctors.
