Online Nutrition Education to Decrease the Side Effects of Chemotherapy in Patients With Breast Cancer

This trial tests an online nutrition education program focused on decreasing nutrition-related side effects of chemotherapy in patients with breast cancer. Patients undergoing chemotherapy are at risk for complications such as diarrhea or constipation which can lead to poor nutritional intake and malabsorption of nutrients. This study is testing the effects of information delivered via the Cook for Your Life website in conjunction with standard clinical care to improve symptom management during chemotherapy treatment for breast cancer, which could serve as a new model for supportive oncology care.

Inclusion Criteria: * 18 years of age or older. * Stage I-III breast cancer. * Current breast cancer patients scheduled to receive ddAC-T(+/-C), TCHP, or TCPembro-AC chemotherapy at Fred Hutch South Lake Union (can enroll prior to receipt of 2nd cycle). * Not pregnant and no plan to become pregnant during chemotherapy treatment. * Ability to speak and read English. * Access to smartphone, tablet, or computer and Internet. * Willing and able to complete all study activities through the end of chemotherapy, including completing online questionnaires and telephone assessments. * Women must not be pregnant at time of enrollment based on self-report. * Able to understand and willing to sign written informed electronic (e) consent in English.
