Rancic's breast cancer diagnosis raises questions about in vitro fertilization

Fans of the "Giuliana & Bill" reality show are aware that E! News anchor Giuliana Rancic has been trying to get pregnant with the help of in vitro fertilization (IVF).

However, as Rancic was about to try a third round of assisted reproduction, her new doctor insisted that she get a mommogram first, even though she is only 36 years old. The screening revealed she had early stage breast cancer.

Senior medical correspondent Elizabeth Cohen joins American Morning today to discuss Rancic's diagnosis and the potential link between cancer and fertility treatments.
