Medical interventions refer to actions taken to improve a patient's health or manage a medical condition. These can include a wide range of procedures, treatments, and therapies, such as surgery, medication, physical therapy, and vaccinations. The goal of these interventions is to alleviate symptoms, cure diseases, or prevent health issues from worsening. Interventions can be classified as either preventive or therapeutic. Preventive interventions aim to reduce the risk of disease, such as screening tests and immunizations. Therapeutic interventions focus on treating existing conditions, like chemotherapy for cancer or insulin therapy for diabetes. Each intervention is tailored to the individual needs of the patient.
