Removing Pectoral Muscle Mammogram

I have an image below. I would like to remove the pectoral muscle on the left. I have used imclearborder() function but it does not remove the pectoral muscle successfully. Are there any other methods I can do to remove the region?

Why did that not work? What does "remove" mean to you? The image must remain rectangular. Do you want to blacken the area in the original gray scale image that corresponds to the pectoral muscle? By the way, if the breast touches the bottom of the image you could get into trouble. The way around that is to write "false" into all outer edge pixels of the image where you do not expect a breast to be. That way only the pectoral blob will be removed.

% Get rid of blobs touching the edge of the image.
noBorder = imclearborder(binaryImage);
% Get the blob representing only the pectoral muscle.
pectoralOnly = xor(noBorder, binaryImage);
% Blacken the pectoral region in the original image.
grayImage(pectoralOnly) = 0;

How could someone do that in a meaningful way without an image to view. We like to have images when we suggest image analysis algorithms. I already asked this of you here in this link but you did not respond there for some reason - you did it here. Can you post your image and non-working code in that question? Or did you finally get it working?
