Prospective Breast Cancer Biospecimen Collection

This is a breast cancer biospecimen and possible metastasis procurement study with the goal of obtaining specimens appropriately for genomic and proteomic analysis. Other than reviewing and signing the consent form by the participants in the study, and the study-specific blood tissue procurement and blood draw (and optional biome specimen), all care and clinical encounters will be as per standard of care. There are four times when tissue may be procured and an optional biome specimen collection depending on the treatment course the treating team decides upon. The technique will be chosen based on physician discretion, patient medical treatment, and patient preference. Treatment regimen will consist of tumor sampling/extraction, one blood draw, optional biome specimen collection, and sample storing. This is a single arm study; all participants will have tissue and blood sample procured for biospecimen analysis and repository. Patients have the option to donate a biome specimen as well. Providing the biome sample is optional and will not influence eligibility to patient participation in this study. There will be no assignment or randomization to different treatment groups.
