Read our Breast Cancer research guide →This trial is creating a tissue and blood sample repository — essentially a research library — from patients with breast cancer at various stages of their diagnosis and treatment. Researchers will use these donated samples to study breast cancer biology, proteins, and genetics to help answer important questions about the disease. By participating, you would be contributing to research that could help future patients.
Scientists need access to real breast cancer tissue and blood samples from patients to understand how the disease develops, progresses, and responds to treatment. This repository will make it easier for researchers to conduct studies that could lead to better diagnosis methods and treatment options.

Your involvement would include having core needle biopsies (small tissue samples collected with a needle) taken from your breast cancer at baseline and potentially at other time points depending on your treatment plan. You would also provide blood samples and complete surveys about your health and medical history. The exact number of biopsies and follow-up visits depends on which group you join — for example, patients receiving chemotherapy before surgery may have biopsies taken before and after starting treatment, while those with recurrent cancer would have samples taken at the time of recurrence.
