The purposes of this study are (i) to obtain and study biospecimens from patients with breast cancer that has either spread out of the breast or recurred after initial treatment(s), such as surgery, chemotherapy, and/or radiation, and (ii) to collect information about patients, treatments, and the behavior of the underlying cancer. Research involving biospecimens that are linked to related medical information is one way to learn more about diseases. In this case, we seek to understand the mechanism of tumor spread and determine why people respond differently to specific cancer treatments. In general terms, scientists will study the cells, DNA, RNA, and proteins found in the tumor tissue and/or the blood to understand more about cancer and the body’s response to cancer and related treatments.
