Pathology report question

Caeryn23

I had a biopsy last thursday. Two thngs the biopsy found were duct ectasia, and fibroadenomatoid changes. It also says there are "predominantly extensively sclerotic breast parenchmya with sparse scattered benign ducts and lobules." The gross description says, "the rubbery consistency of the tissue extends to all 6 inked margins."

Are any of these proliferative changes? What does sclerotic mean? What does the margin part mean? Thank you.
