The best part is that it's very easy with this tool because you can do all of your research online before going into surgery! I also like how simple everything was when creating my account so far but there are still some things missing which i think will be added soon such as being able create different types (ie bony or cartilaginous) tumors etc..
It would have been great if they included more tumor examples too since we don't know what kind our surgeon wants us doing yet until he comes out after looking at them himself.
