Personalized medicine is a medical approach that tailors treatment to individual patients based on their unique characteristics. This can include genetic information, lifestyle, and environmental factors. By understanding these differences, healthcare providers can choose the most effective therapies and medications for each person, improving outcomes and reducing side effects. This approach often involves the use of advanced technologies, such as genomic sequencing, to identify specific biomarkers related to diseases. Personalized medicine is particularly prominent in fields like oncology, where treatments can be customized to target specific types of cancer based on a patient's genetic profile.
