This study focuses on people with breast cancer who have aromatase therapy-associated musculoskeletal symptoms. The purpose of the study is to determine whether tart cherry concentrate and fish oil, when taken together, have an impact on arthritis symptoms in these patients. Researchers will also assess whether tart cherry concentrate and fish oil have an impact on pain, functional performance, quality of life, and cognition. Additionally, the study will evaluate whether these dietary supplements change the composition of the blood. A biomarker is a biological molecule found in blood, other body fluids or tissues that may be a sign of a condition or disease and can be used to predict response to a specific treatment. Biomarker samples will be stored for future analysis and studies related to the mechanisms by which arthritis symptoms occur in aromatase inhibitor therapy. Tart cherry concentrate and fish oil are commercially available but have not been approved by the U.S. Food and Drug Administration (FDA) for the purpose intended in this study.
