EARLY CANCER DETECTION USING BIOPHYSICAL METHODS: BASED ON AMERICAN EXPERIENCE

Abstract

Early detection of cancer is one of the most promising strategies to decrease mortality and improve the effectiveness of treatment. The American experience in this field demonstrates the crucial role of biophysical methods in identifying oncological diseases at their earliest stages. Biophysical diagnostic tools, including magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), optical coherence tomography (OCT), and ultrasound elastography, allow non-invasive assessment of tissue structure, metabolism, and elasticity, revealing abnormalities long before clinical symptoms appear.     In the United States, the combination of these imaging techniques with molecular diagnostics and artificial intelligence systems has greatly improved diagnostic precision and patient outcomes. Recent innovations such as nanoplasmonic sensors, quantum dots, and biosensors enable highly sensitive detection of cancer biomarkers in blood, forming the foundation for liquid biopsy technologies. This integration of biophysical and digital methods supports real-time tumor monitoring and personalized medicine approaches.  The American model highlights the importance of preventive screening programs such as mammography and low-dose CT scans—supported by advanced imaging and data analysis. As a result, early detection rates and survival outcomes have markedly improved across various cancer types. Overall, biophysical methods represent a vital component of modern oncology, ensuring timely diagnosis, accurate treatment planning, and a higher quality of life for patients.
