According to an insertion support system of the present invention, when a biopsy area is specified at a periphery of the bronchi, the barycenter of the biopsy area is extracted. A circle centering on the barycenter is determined as a search area. The search area is expanded until the bronchi are located within the search area. A point in the search area to which the bronchi first reach is determined as an end point. A first route choice connecting the end point and a start point is determined. If the first route choice has not been registered yet, the first route choice is registered as a first registered route. Accordingly, a location of interest can be specified as an arbitrary region, and navigation leading to the specified region is appropriately set.
