I am currently seeking shadowing opportunities and I included my resume in all of the emails I sent out. I thought it was a good idea mainly so that doctors could get a feel for who I am and whether or not I was serious. In some of the responses I've received, it is obvious it was never looked at... but in some other responses, it was obvious that physicians agreed to meet with me based on my past experiences (obviously listed in my resume).
So, YES I would include it, but don't get too stressed about the quality/detail. They will probably just skim it... if anything they may want to see where you go to school, when you will graduate for age purposes (or if you already graduated), what you're currently up to, etc.
