I understand you concern. This finding on a core biopsy signifies a benign condition, however if there are other characteristics of the breast nodule that will point out to a possible malignancy (like irregular gritty borders, associated skin dimpling, hard and fixed nodule) then the doctor might have to do a larger biopsy like an excision biopsy. The fact that you had left breast cancer already makes you at risk of developing another breast cancer at the right, and that this finding of sclerosing adenosis may not add to that risk significantly. I suggest that you continue surveillance with your doctor and that to discuss with him or her if he's comfortable with the core needle biopsy results. Regards and God bless.
