resultant side effects Answer: Lymphoscintigraphy
◍ Lymphoscintigraphy aka Answer: Sentinel node mapping
◍ Lymphoscintigraphy uses injection of radio isotope where?
Answer: Around the tumor
◍ Principle behind Lymphoscintigraphy Answer: First node, sentinel
node, receives drainage from a tumor & can be used to predict
presence or absence of tumor in remaining nodes

under u/s guidance Answer: cyst aspiration
◍ FNA ideal for cyst eval. and aspiration. Uses ___ to ____ gauge
needle Answer: 22-25
◍ which breast intervention usually requires a cytotechnologist eval
of sample Answer: Fine needle aspiration
◍ 3 treatments for breast cancer Answer: surgery, drugs
(chemo/hormone therapy), radiation therapy
◍ _________ removes breast tissue and some of underarm lymph
nodes Answer: modified radical mastectomy
◍ Removal of entire breast, leaving most of the lymph nodes intact
Answer: Mastectomy
, ◍ which mastectomy removes entire breast, lymph nodes, and chest
wall muscles? Answer: Radical mastectomy (RARELY
PERFORMED)
◍ Removal of malignant tumor & the surrounding margins, often
combined w/ chemo, radiation or hormone tx Answer: Lumpectomy
◍ two common types of flap techniques Answer: TRAM, latissimus
dorsi flap
◍ more common form of radiation therapy Answer: External beam,
Uses high energy radiation to destroy cx cells in the chest wall, axilla,
and breast. Can be used in to shrink the tumor before sx
◍ internal beam radiation (brachytherapy) usually lasts ______ to
____ days and can begin immediately after surgery. Answer: 5 to 9
days (instead of weeks). Less irritation of healthy breast tissue
◍ How long is Radiation therapy and how long after surgery can it
begin? Answer: 6 to 8 weeks; 1 month after surgery to allow breast to
heal. Tx time approx: 15-30 mins, 5x/wk
