NCIt definition : A mass in the mammary gland, either mobile or immobile. Once the mass has reached
the size of a small garden pea, it can be detected by palpation. With mammography
a larger number of early breast cancers are being detected since this techniques allows
detection prior to the point at which the mass can be felt. Breast masses are not
always malignant. Benign fibrocystic breast disease is not uncommon. A fine needle
biopsy aspiration can distinguish a cystic mass from a solid one.;
Alternative definition : FDA: Abnormality in the breast parenchyma, identified either by palpation or imaging.
These abnormalities include calcifications, breast tissue distortion, presence of
areas of density, and presence of benign or malignant tumors.;
