I need to use matlab image processing to compare the size of a tumor before treatment and after treatment (images shown below), basically I just need to be able to measure the area of the tumor in each image and do a comparison between the two to see how much it has shrunk.

You can use Image Segemeter app to segment the image using thresholding, for details follow this link:

Then you can measure diffrent properties of image regions like 'area', 'eccentricity', etc. using regionprops function.
