After chemotherapy, surgery and/or radiation, most breast cancer survivors take medications for at least 5 years to prevent the dreaded disease from returning. That may change.

Scientists continue to advance their understanding of how breast cancer develops and progresses. Knowing where the disease is headed offers powerful new alternatives.

Breast cancer cells frequently rely on the hormone estrogen to develop and grow. New research has discovered more about this relationship, findings that could lead to new, better treatments.

Just as the old saying goes, "You are what you eat," scientists have now learned that what cancer cells eat predicts how aggressive they are. These new findings can be used to offer better and more personalized cancer treatment.
