My question is I need to extract that blue polygon tumor suspicious region from original image and then I will segment that extracted image.

Once you have the mask, do this:
% Mask the image using bsxfun() function to multiply the mask by each channel individually.
% Works for gray scale as well as RGB Color images.
maskedImage = bsxfun(@times, rgbImage, cast(mask, 'like', rgbImage));
changing the names to whatever you want to call them.
