What does the suffix "-iatry" indicate in the context of healthcare?

The suffix "-iatry" is used in medical terminology to indicate a branch of medicine concerned with the treatment of a particular condition or group of conditions. It implies a focus on not just studying medical phenomena but actively providing medical treatment and intervention. For example, "podiatry" refers to the treatment and care of foot-related conditions, while "psychiatry" refers to the medical treatment of mental health disorders.

While some other suffixes or terms may relate to study, research, or patient care, "-iatry" is distinctly associated with medical disciplines that encompass therapeutic practices aimed at improving health outcomes for patients. This is why the answer regarding medical treatment is the most accurate choice in this context.
