Cervical cancer usually causes pain in the anterior iliac and sciatic nerve distribution of the leg, but there may also be localized pain in other parts of the leg. Generally, when cervical cancer develops into advanced stage, it will cause pain in the anterior iliac position due to the gradual enlargement of the tumor, which will exert pressure on the pelvis. If the tumor is located backward, it will press the sciatic nerve in the waist, which will also cause pain in the corresponding sciatic nerve circulation area in both legs. Besides, cervical cancer will metastasize in the late stage, and if it metastasizes to the bones of the lower limbs, the cancer cells will compress the nerves and tissues and invade the nerve endings, which will also cause pain, usually localized pain, and the pain is severe and unbearable. It is recommended that patients should consult doctors in time to treat and relieve pain under doctors’ guidance.
