I am of two minds on this.  I have read some opinions that you don't need 
a Cancel action at all (be it a button or a link), that you just need to 
provide the user with clear alternatives to proceeding.  I'm not convinced 
of that, however; at least not in the general case.  On the one hand, it 
seems to me that people are accustomed to having a Cancel option in dialog 
boxes and tend to expect the same elsewhere (e.g., Web apps).  On the other 
hand, I suspect that "Return to X" would *be* such a clearer alternative.
I do think it should be a button rather than a link, precisely because it 
conveys the impression of performing an action rather than simply navigating.

I agree with you, Claudia.  If it takes an action, make it a button, 
regardless of whether it also has the side effect of taking the user 
somewhere else.  The user expects to see things change on clicking a 
"Cancel" button.  In this case, navigation is not specifically the user's 
intent, and a link is not the appropriate mechanism for it.
