The importance of genetic screening in disease prevention lies in its ability to identify individuals at risk for hereditary conditions. By analyzing genetic material, healthcare professionals can detect mutations that predispose individuals to diseases such as breast cancer, cystic fibrosis, and cardiovascular disorders. This information allows for early intervention, personalized treatment plans, and informed reproductive choices, thereby reducing the disease burden on individuals and families. Genetic screening also enhances public health strategies by identifying at-risk populations and guiding research in preventive medicine.
