- B. The cancer cells look like normal cells.
- C. Further testing is needed to determine the spread of the cancer.

B's wrong grading, not staging, covers cell look (differentiation). C's off no spread's confirmed already. D's nonsense the cervix is the origin. Nurses break this down in oncology to ease fears only the cervix' signals a shot at cure with local treatment, not systemic chaos yet.
