Q

The appearance of free silicone within a lymph node is consistent with a diagnosis of

A

Extracapsular rupture

23
Q

Why is needle wire localization preferred over skin localization method?

28
Q

Branch of biology dealing with the structure, function, multiplication, pathology and life history of cells

A

Cytology

29
Q

During a needle localization procedure using an ultrasound approach, deep lesions are best:

A

30
Q

Most likely sonographic appearance of capsular contracture

A

31
Q

Following lumpectomy, approximately what percentage of patients develop seromas?

A

50%

32
Q

On the CC view of a mammo, markers should be placed:

A

Lateral outer aspect of the breast

33
Q

The purpose of sentinel node mapping is______

In reference to mammographic views

36
Q

Most common indication for galactography

A

Single duct discharge and normal mammo

37
Q

When would incisional biopsy be useful?

A

If the lesion is large and poorly defined

38
Q

Most accurate for intraoperative breast specimen imaging

A

Specimen mammography and ultrasound

Following radiation therapy, a patient may demonstrate ________ for up to 2 years

A

Skin thickening

40
Q

Axillary lymph node dissection procedure typically removes _________

A

10-15 lymph nodes

41
Q

A lesion visualized on ultrasound will appear closer to the chest wall than the same lesion found on mammo

A

True

42
Q

The delivery of treatment prior to surgery in order to shrink the cancer

A

Neoadjuvant therapy

43
Q

Breast abscess drainage is most successful when the abscess is:

A

Less than 2.5cm

44
Q

Which region of the breast is the most poorly demonstrated on the MLO mammo projection?
