Is there a command on matlab that detects only the outer edge of an image ?

I am working on the detection of breast cancer, and I need a command Matlab that detects only the outer edge of the breast

There is no higher level breast edge detector in MATLAB. If the background is a lot darker than the breast, you can threshold and call bwboundaries. Post your breast image and I can maybe do a demo.

In what form do you want the "outer edge"? A list of boundary (x,y) coordinates? A binary mask image? A binary image of just the outline / perimeter?
