This trial studies disseminated tumor cells in blood and bone marrow samples from patients previously treated for breast cancer. Studying samples of blood and bone marrow from patients with breast cancer in the laboratory may help doctors to determine whether there are any dormant tumor cells in the body. It may also help doctors to better understand what disseminated tumor cells are and how they can be best treated to improve the treatment and prevention of breast cancer in the future.

PRIMARY OBJECTIVE:
I. To determine the incidence and frequency of bone marrow in patients who have completed primary treatment for breast cancer for eligibility to a recurrence prevention trial.
SECONDARY OBJECTIVES:
I. To compare the frequency and concordance between an immunohistochemical assay (disseminated tumor cells [DTC]-immunohistochemistry [IHC]) and flow cytometric-based assay (DTC-Flow) to detect DTCs in patients who have completed primary treatment for breast cancer and are undergoing surveillance.
II. To compare the molecular and genetic features between primary tumor and disseminated tumor cells (DTCs) among those patients who harbor DTCs.
OUTLINE:
Patients undergo blood collection and bone marrow aspiration for DTCs assessment via DTC-IHC, DTC-Flow, whole exome sequencing, and ribonucleic acid sequencing (RNA-seq).
