 The goal of this clinical research study is to find out if the parametrial nodes are sentinel nodes the lymph nodes believed to be the greatest risk for the spread of cancer and if intraoperative lymphatic mapping can identify sentinel lymph nodes in the parametrium the tissue that is on either side of the cervix. Identifying these lymph nodes may help to predict the status of the remaining lymph nodes in the pelvis. This research will also determine if India Ink is safe to use with the blue dye and radioactive tracer and if it improves the process of identifying the sentinel nodes.
