What are the three types of treatment? Three types of treatment commonly categorized are curative, palliative, and preventive treatments, though classifications vary. Curative treatment aims to cure disease and restore health, such as antibiotics curing bacterial infection, surgery removing diseased organ, or chemotherapy curing cancer. Palliative treatment aims to relieve symptoms, improve comfort and quality of life when cure not possible, such as pain management, hospice care, and symptom control in advanced cancer. Preventive or prophylactic treatment aims to prevent disease or complications, such as vaccinations, lifestyle changes, and medications to prevent heart disease. Another classification includes primary treatment which is main treatment for disease, adjuvant treatment which is additional treatment after primary to reduce recurrence, and neoadjuvant treatment given before primary to shrink disease. So three main types are curative aiming to cure, palliative aiming to relieve symptoms, and preventive aiming to prevent disease, covering major goals of medical treatment.
