Due to their ability to simulate human conditions, xenograft models such as CDX (Cell line-Derived Xenografts) and PDX (Patient-Derived Xenografts) have gained popularity in pre-clinical research. The choice of xenograft technique is influenced by the type of tumor employed, particularly in more aggressive tumor models like TNBC with metastases.

Late 19th century histologic evidence that cancer begins as a single primary focus and Halsted's centrifugal theory of stepwise spread (breast, regional nodes, and systemic distribution) provided the rationale for both en bloc surgery and the lifesaving benefit of early detection. Clinicians soon noticed exceptions to this ordered timeline, and pathologists identified histological features that questioned its primacy; however, Bernard Fisher spearheaded the initial challenge. His groundbreaking hypothesis that breast cancer was systemic from its inception was supported indirectly by the 3rd arm of National Surgical Adjuvant Breast and Bowel Project (NSABP) B04 and B06. These trials bolster his contention that a patient's fate was dependent on shed cells rather than the extent of the operation; however, the breast cancer wars of the 1970s focused on competing local treatments. When follow-up data revealed equivalent survival results, it established lumpectomy/radiation as equal to mastectomy, but overlooked Fisher's attack on Halsted's theory. Two mid-20th century medical innovations also played a role in the history of early detection: population-based screening by detecting cancer before it became clinically evident, and repurposing systemic treatment designed for metastatic recurrence into adjuvant chemotherapy.
