Q

The American cancer society recommends what for early detection of breast cancer

A

Women should be familiar with how their breasts normally look and feel and should report any changes to health care provider
Women between 40-44 have the option to start screening with a mammogram every year
Women 45-54 should get yearly mammograms
At 55 women can switch to every other year

0- incomplete
1- normal; annual
2- benign; annual
3- probably benign, short-term follow up

Q

3D vs 2D mammography

A

3D (digital breast tomosynthesis) decreases call backs, increases CA dx, better in dense breasts, increased costs

Q

If a diagnostic study is needed, what technique is obtained first?

A

Standard two view mammogram

17
Q

What should be made known to the radiologist when you order imaging for a suspected mass?

A

The location and description of a suspected breast mass

18
Q

What are the indications for ultrasonography?

A

Detected, indeterminate mass
Palpable mass not seen on mammography
Palpable Mass on patient under the age of 40
Significantly dense breast

19
Q

Ultrasound is highly reliable for

A

Differentiating cystic from solid masses

20
Q

If the criteria for a simple cyst are met, the diagnosis is over ___% accurate

A

99%

21
Q

What are limitations of ultrasound

A

It is operator dependent
Only images a small part of the breast at one moment

22
Q

What is the first Indication of image guided needle aspiration and biopsy

A

To confirm dx, relieve pain or both

23
Q

Cystic fluid is not routinely sent for cytology unless

A

It’s bloody

24
Q

What is the second indication for image guided biopsy? What is used for this?

A

Solid lesions- core needle biopsy is used in this case

25
Q

Why is core needle biopsy used for solid lesions?

A

To confirm benignity of a lesion with low suspicion of malignancy
To confirm malignancy in a highly suspicious lesion prior to initiating further surgical planning and treatment
To eval any other lesion for which further imaging or excision is a less desirable option

26
Q

Guidance for needle biopsy can be accomplished with

A

Stereotactic mammography, ultrasound, and MRI

27
Q

What are the most common techniques for needle biopsy guidance

A

Ultrasound and mammography

28
Q

When a non palpable breast lesion must be excised, imaging is used to guide placement of a needle into the breast, with the needle tip traversing or flanking the lesion. What is this called?

A

Image guided needle localization

29
Q

Why is a hook wire inserted after the needle is in the appropriate position during image guided needle localization?

A

This prevents migration during patient transport and surgery

30
Q

Spherical calcifications with lucent centers are typically

A

Benign calcifications associated with fat necrosis and calcified cysts

31
Q

T or F: The majority of breast cysts are malignant

A

False, the majority are benign

32
Q

Breast cysts mostly occur in (older/younger) patients with FCC

A

Younger

33
Q

Breast cysts may indicate ___________, some of which are malignant and may be associated with nipple discharge

A

Intraductal papilloma

34
Q

T or F: breast cysts often recur

A

True

35
Q

On ultrasound breast cancers are ______ while on mammogram breast cancers are _______

A

Black
White

36
Q

What are the 9 possible causes of palpable masses

A

Fibroadenoma, lymph nodes, malignancies, cysts, abscess, galactocele, fibrocystic change, hematoma, fat necrosis

37
Q

What imaging captures multiple images of the breast and combines the images using a computer to create detailed picture

A

Breast MRI

38
Q

What are the indications for breast MRI

A

Preop eval in patients with newly dx breast CA
Eval of breast CA treated with chemo
Eval of breast CA patients with positive surgical margins after breast conservation therapy
Eval of patients with metastatic axillary lymphadenopathy and unknown primary malignancy
Determine silicone implant integrity
CA screening in high risk women
Problem solving tool for equivocal mam findings

39
Q

When should you be concerned about nipple discharge?

A

If it is unilateral, bloody, or spontaneous
