Diagnosis involves identifying a disease or condition based on a patient's symptoms, medical history, and diagnostic tests. Healthcare professionals may use physical examinations, laboratory tests, imaging studies, and other methods to gather information and reach an accurate conclusion about the patient's health. Treatment refers to the management and care of a patient to combat a disease or alleviate symptoms. This can include medications, therapies, surgeries, or lifestyle changes. The chosen treatment plan often depends on the specific diagnosis, the severity of the condition, and the patient's overall health and preferences.
