why might we see reduced fibrous connective tissue in the breast
- increased age–> fatty replacement

margin of echogenicity, irregularly shaped, inner hypogenecity, posterior shadowing
how would we insert a needle for biopsy into the breast?
from below the breast, parallel to the chest wall
what might bright focal lesions on a mammogram suggest?
calcification
if you saw a popcorn appearance of coarse calcification lesions on a mammogram, what would you think?
fibroadenoma
if you saw micro calcification lesions- what would you think?
Ductal carcinoma in situ
what might indicate malignancy on the mammogram?
microcalcification lesions and stellate appearance that is irregularly shaped
