Has anyone encountered a problem when filing form I-485 without evidence of medical record in the package?

Per instruction on form I-485, it did ask for your medical record. I am not going to include this in the package since USCIS already has a copy in their file as recently as 7 to 8 months ago when my fiancee has her medical exam & entered the US. I heard somewhere in VJ discussion forum that we do not need to include this evidence (medical record) in this package. Is it true that we need not include? If this is the case, then I'll want to avoid it altogether. Any one shed a light on this subject.
