Breast cancer is one of the leading causes of cancer deaths worldwide. Diagnosis and treatment are usually quite challenging. The standard techniques of diagnosis, like MRI and CT scans, often lack the ability to detect the disease in its early stages, while invasive ones like biopsy may include certain discomfort and risks. Nanotechnology, a type of technology that operates at the molecular level, offers solutions to these challenges. It talks about the application of nanotechnology in the detection and treatment of early-stage breast cancer, focusing on nano-enabled biosensors and nanoparticles. Nano-enabled biosensors can detect cancer biomarkers in body liquids, providing a non-invasive alternative to the conventional techniques of imaging. At the same time, nanoparticles enhance treatment efficacy owing to their potential for precise targeting of cancer cells, which reduces the side effects compared to conventional chemotherapy. This review also explores recent preclinical and clinical studies discussing the latest advances, such as bifunctional nanoprobes, fluorescent nano sensors, and ultra-pH-sensitive nanoparticles. Despite these advances, certain challenges remain regarding both biocompatibility and long-term safety. Continued research and exploration will be necessary fully to utilize the potential of nanotechnology in improving the detection and treatment of breast cancer. Basically, nanotechnology represents a huge step in the development of early detection and effective treatments, which can ensure happier and healthier patients.
