A medical specialist is a doctor who focuses on a specific area of medicine, such as cardiology, neurology, or pediatrics. These professionals have completed additional training and education beyond general medical school, allowing them to diagnose and treat complex health issues related to their specialty. Medical specialists often work in hospitals, clinics, or private practices, collaborating with other healthcare providers to ensure comprehensive patient care. They may perform specialized procedures, interpret diagnostic tests, and develop treatment plans tailored to individual patients' needs.
