Mammography Questions And Answers
Verified by Experts
Benign, malignant Masses consisting of mostly fat are usually _______, whereas masses
consisting of variable fibroglandular tissue could be _______.
UOQ Most cancers are detected in the _______ of the breast
98% Percentage of axillary lymph nodes located in UOQ
Radial scar, fat necrosis, breast abscess, sclerosing adenosis Examples of benign stellate
lesions
Fibroadenoma, cyst, intramammary lymph node, hematoma, galactocele Examples of
benign circumscribed masses
15-25% Approximately _______ of microcalcifications found in asymptomatic women
are associated with cancner
Needle-wire localization for open surgical biopsy, fine-needle aspiration biopsy (FNAB), large-
core needle biopsy (LCNB) Nonpalpable breast lesions can be localized using three
techniques:
, Mammography Questions And Answers
Verified by Experts
Needle-wire localization Uses a needle that contains a hooked guidewire to lead the
surgeon directly to the suspicious tissue
FNAB Uses a hollow small-gauge needle to extract tissue cells from a suspicious lesion
FNAB Can potentially decrease the need for surgical excisional biopsy by identifying
benign lesions and by diagnosing malignant lesions that require extensive surgery rather than
excisional biopsy
LCNB Obtains small samples of breast tissue by means of a 9-gauge, 11-gauge, or 14-
gauge needle with a trough adjacent to the tip of the needle
Needle-wire localization Predominant method for localizing nonpalpable lesions for open
surgical biopsy
Kopans, Homer (18-gauge), Frank (21-gauge), Hawkins (20-gauge) The four most
common needle-wire localization systems are the ______, _______, _______, and _______.
80%, not malignant Approximately _______ of nonpalpable lesions identified by
mammography are ___________
Stereotactic intervention A minor surgical procedure used to determine the benign or
malignant nature of suspicious breast lesions
