How can you describe excruciating leg pain in a cervical cancer. Does all leg pain is associated with cervical cancer?

This question. Needs to go to your gynoncologist or rad onc treating you. My largest concern is sciatic nerve invasion, but bony disease can also do this. So, you need an exam, updated imaging and possibily a biopsy.
What stage. Leg pains could be due to unrelated vascular problem, or in late stages nerves, vessels could be encroached by the tumor.
