with a similar shape on two views

conspicuity.

of less than one quadrant of
the breast and is of more concern.
The frequency of finding focal asymmetry at screening
mammography is less than 1%.

asymmetry where at least one

is new or increased in conspicuity
compared with the previous mammogram.
It is challenging to evaluate, as it often looks
similar to fibroglandular tissue
at mammography.
A developing asymmetry should be viewed with suspicion
because it is an uncommon
manifestation of breast cancer.
