A lesion like this can be characterized as a fibroadenoma, but it has some unusual characteristics (micro lobulation, non-parallel orientation).
Taking into consideration family and personal history, lesion's characteristics and the fact that the patient had her first imaging breast examination at the age of 50, I decided to grade this as a BIRADS IV lesion.
I suggested her to perform a mammography immediately, but she refused.
My final report was BIRADS IV for the right breast, and also a strong advice for a mammography as soon as possible because of the further lesion evaluation.
