Surgery is a broad category of invasive medical treatment that involves the cutting of a body for a specific reason such to remove a diseased organ or to repair a tear or breakage. Surgeons may be physicians, dentists, podiatrists.
Minimally invasive procedures such as the procedures of interventional radiology are sometimes described as "minimally invasive surgery." The field traditionally described as interventional neuroradiology, for instance, is increasingly called neurointerventional surgery. Robotic surgery is an area of growing interest.
