My Mother was diagnosed w/ stage 1b2 cervical cancer and has positive lymph nodes. She needs to undergo chemo and both internal/external radiation. She also has constant back pain and needs to take pain med. in order to control her pain daily. I believe the reason is b/c, in her case, they left the cervix and uterus intact in order to protect the adjacent vital organs during radiation. Ask if you had your cervix removed b/c in certain cases when there are positive lymph nodes they treat the cancer with radiation and chemo. and leave the uterus/cervix intact.
