The details of your examinations would be in the actual reports that were sent to your prescribing Physician so you might ck. with that office for a copy. Microcalcifications are an indication that some abnormality is present within the breast tissue ... NOT necessarily something malignant. I think the 6 month re-check is a proper recommendation since the findings did show cysts. If something is truly "highly suspicious" then a biopsy is usually recommended so this may have been an overuse of the term "highly suspicious". If I were you I would contact your Dr.s office and request that he/she sit down with you and discuss the reports in detail. I don't see a need for a second opinion as that would merely be having your films read by another Radiologist. Regards ....
I had microcalcifications (bilateral and scattered) that were "watched" on every 6 month mammograms for over a year. On the most recent mammogram, an increased cluster was seen on the right breast. The radiologist recommended a stereotactic needle biopsy. This came back as ADH (atypical ductal hyperplasia). An excisional biopsy (lumpectomy) was then recommended. This was done by a breast surgeon. The pathology result came back as borderline ADH/DCIS (ductal carcinoma in situ). For me, it was important to remove this abnormal tissue before it had a chance to develop into invasive cancer. You definitely want to stay on top of the 6 month follow-up mammogram. If you do not feel comfortable with this and want to be more aggressive, you could request a biopsy. To put your mind at ease though, according to my research, most biopsies do come back negative.
