Recent Breakthroughs in Breast Cancer Endocrinology and Tumor Microenvironmental Interactions

Breast cancer remains one of the most prevalent and lethal cancers among women worldwide, accounting for a significant proportion of cancer-related morbidity and mortality. Recent advancements in endocrinology have significantly contributed to understanding the disease’s complex mechanisms, leading to more effective treatments and improved patient outcomes. This review highlights the latest breakthroughs in breast cancer endocrinology, focusing on a variety of hormones and their involvement in tumor progression. Additionally, the review explores the effects of hormones in modulating tumor metabolism, including the metabolic reprogramming that cancer cells undergo to support rapid growth and survival. The impact of endocrine factors within the tumor microenvironment is also examined, shedding light on how hormonal signals from surrounding stromal and immune cells can affect tumor behavior and response to treatment. Furthermore, the review delves into potentially new hormone therapies in breast cancer treatments. Innovations in selective estrogen receptor modulators (SERMs), selective estrogen receptor degraders (SERDs), and other hormone-targeting agents have shown promise in overcoming resistance to traditional hormone therapies. These breakthroughs underscore the critical role of endocrinology in the ongoing fight against breast cancer. By elucidating the complex interactions between hormones and breast cancer cells, researchers are paving the way for more targeted and effective therapies.
