Summary

This study tests whether a program of motivational counseling to follow diet and exercise guidelines helps women newly diagnosed with breast cancer complete their chemotherapy and hormone therapy as planned. About 173 women scheduled for chemotherapy will be randomly assigned to receive the counseling or standard care. The goal is to see if lifestyle support can improve treatment adherence and body composition.
