Welcome to Mayo Connect, for the most part, we are not medical professionals, instead we are patients and caregivers sharing experiences, asking advice and supporting each other.
Radiology imaging reports can be very technical and hard to interpret.
I understand your concern about cyst, especially with your family history.

Do you have a follow appointment with your provider to help you understand results? Ask about a biobsy or a if a MRI should be schedule due to dense breast.

Another suggestion, based on family history, has anyone suggested genetic testing?
