Introduction: The quest for more precise diagnostics and effective treatments is unending. Cancer, with its multifaceted nature and ability to adapt, necessitates innovative approaches to diagnosis and treatment. One such innovation that holds immense promise is the utilization of circulating tumor cells (CTCs) as biomarkers. CTCs, shed from primary tumors or metastatic sites into the bloodstream, offer a window into the dynamic nature of cancer, providing insights into disease progression and treatment response. This blog discusses the burgeoning field of CTC research, exploring their utility as biomarkers for diagnosis, prognosis, and treatment monitoring, and their potential to drive advancements in…
