1. A method for the segmentation of a lesion, comprising the steps: providing an image region selected from a digital image with a recorded lesion; determining a starting region for the lesion in the image region, wherein the starting region has a starting region outer contour; determining a quantity of candidate regions for the lesion in such a way that each candidate region has a candidate region outer contour including the starting region outer contour, two respective adjacent candidate regions form an inner candidate region and an outer candidate region with respect to one another, and the candidate region outer contour of each outer candidate region includes the candidate region outer contour of the associated inner candidate region, and selecting a candidate region closest to the lesion from the quantity of candidate regions.
