Dear sharonl: This report describes normal breast tissue with no areas of concern. It is usual when one has had a biopsy to evaluate in 6 months. One reason is to get a new baseline now that the breast anatomy has been altered. Please continue to have your annual mammograms. If a cancer is ever found, it is best to find it early.
Bottom line: the words describe very common findings, none of which are considered worrisome or associated with cancer risk. To list some of the words: "parenchyma" is just a way of saying normal tissue, really. "Fibrosis" is scar tissue, very common in the breast, not of significance. "Atypia," which they did not see, can sometimes be associated with risk, so they pointed out it wasn't there. "Lactiferous cysts" are common, harmless cysts related to the milk producing areas. "Fibrocystic" changes are present to some degree in most women after a few years of owning breasts. All in all, it's a perfectly safe report.
