A medical license is an official authorization that allows a healthcare professional, such as a doctor or nurse, to practice medicine legally. This license is granted by a regulatory body, often at the state or national level, after the individual has completed the necessary education, training, and examinations. To maintain their medical license, professionals must adhere to specific standards and may need to complete continuing education courses. This ensures that they stay updated on the latest medical practices and technologies, ultimately promoting patient safety and quality care in the healthcare system.
