When cervical cancer develops to the late stage, the cancer cells will spread and metastasize, and at this time, bone metastasis is more common. When bone metastasis occurs, cervical cancer patients will feel obvious pain symptoms, and the main part of the pain is at the metastasis site. When bone metastasis occurs, the pain symptoms are relatively mild and intermittent, but with further development of the disease and further spread and metastasis of cancer cells, the pain will develop into persistent severe pain, which is intolerable to the patients, and is often accompanied by localized pressure and swelling, and even functional disorders and pathological fracture will occur. If cervical cancer bone metastasis reaches the spinal column, patients will have symptoms of compression of spinal cord and nerve roots. Patients with bone metastasis are often accompanied by local inflammatory changes, and at the same time, there are symptoms of general exhaustion, such as body wasting, fatigue and weakness. Nowadays, as long as there is a certificate for pain caused by cancer, morphine analgesics can be prescribed to alleviate the patient’s pain.
