Breast cancer stem cells origins and the memory stem cells: clinical significance of biomarkers and the active therapeutic approaches

Despite recent improvements in diagnosis and treatment, breast cancer (BC) remains one of the leading causes of cancer-related deaths among women. In this complex disease, breast cancer stem cells (BCSCs) are a small but significant subset of different cancer cells with the ability to proliferate and self-renew. According to an increasing amount of studies, BCSCs are essential for breast cancer metastasis, drug resistance, and recurrence. Due to its diverse nature, BC includes numerous subtypes, each of which displays unique BCSC types and concentrations that are connected to different therapy outcomes and outcomes. Despite significant advancements in the treatment of early-stage breast cancer, there are still few effective therapy approaches for metastatic BC. The development, progression, and dissemination of BC are largely attributed to cancer stem-like cells (CSCs), which are characterized by their exceptional adaptability and self-renewal ability. An overview of the development of BCSCs, their biomarkers, clinical significance, and the mechanisms behind their behavior is the goal of the current study. The active therapy strategies being employed to address BCSCs will also be examined.
