What does the term "non-invasive" refer to in medical procedures?

The term "non-invasive" in medical procedures refers to techniques that do not involve entering the body. This means that non-invasive procedures can be performed on the surface of the body or through external methods, without the need to penetrate or damage internal tissues. Examples of non-invasive procedures include imaging techniques like ultrasound, MRI, and certain types of physical therapy.

This distinction is significant because non-invasive methods are typically associated with fewer risks, shorter recovery times, and less discomfort for the patient compared to invasive procedures. While other choices may involve methods related to care, they do not align with the definition of non-invasive, highlighting the importance of maintaining the body’s integrity during such procedures.
