Spiculated nodule in left breast in association with skin retraction and axillary adenopathy: BIRADS 5

Left nodule progression


Screening mammogram LMLO view showed a small nodular lesion with undefined margins in the left upper quadrant of the breast, no adenopathies. ​3 years later, the lesion has grown considerably, from 10 mm to 31 mm, it has spiculated margins and there's presence of skin retraction and axillary adenopathy.

Case Discussion
