Genomic medicine is a branch of medicine that uses information from a person's genome to improve health care. The genome is the complete set of DNA, including all of its genes. By analyzing this genetic information, doctors can better understand diseases, predict health risks, and tailor treatments to individual patients. This approach allows for more personalized medicine, meaning treatments can be customized based on a person's unique genetic makeup. For example, certain medications may work better for some individuals than others, depending on their genetic variations. This can lead to more effective and safer treatment options.
