  • Lobular carcinoma
  • Multicentric cancers
17
Q

Shrunken breast?

A

Invasive lobular carcinoma

18
Q

DDx for architectural distortion?

A

Post surgical scar
Breast cancer (IDC or ILC)

19
Q

Type of cancer?
What’s going on?

Bonus, what if the breast were small with thickening?

20
Q

WHEN can you call a BI-RADS 3?

A

Diagnostic mammo, baseline exam (no priors)

21
Q

WHAT findings qualify as BI-RADS 3?

A
  1. Grouped round calcifications on a BASELINE
  2. Looks like a fibroadenoma on a BASELINE (could grow = phyllodes)
  3. Focal asymmetry without calcs or distortion on a BASELINE
22
Q

How long is followup on a BI-RADS 3?

A

2 years (or upgrade if the findings changes)

23
Q

BI-RADS 3 = __% chance malignancy?

A

<2%

24
Q

BI-RADS 4 = __% chance malignancy?

A

2%-95%

25
Q

BI-RADS 5 = __% chance malignancy?

A

> 95%

26
Q

Nipple discharge… what 3 things do you want to know?

A

Spontaneous?
Bloody?
Single duct?

27
Q

What kind of breast cancer do men get? Why?

A
  • Ductal
  • Male breast tissue does not form lobules
  • NO lobular carcinoma
  • NO fibroadenoma
  • NO cysts
28
Q

Causes of gynecomastia?

A

Drugs and meds - Psych meds; spironolactone; marijuana

Conditions - cirrhosis; testicular cancer

Normal <13yo or >65yo

  • Dendritic (not painful)
  • Diffuse (woman’s breast; think estrogen therapy)
30
Q

Scary breast mass in a male patient… next best step?

A

Mammography

Don’t jump to biopsy… nodular gynecomastia can look scary. Needs mammo for further characterization

31
Q

What is pseudogynecomastia?

A

Increase in fat tissue in the breast, but NO glandular tissue

32
Q

Implant associated breast cancer?

What increases risk?

Associated with saline vs silicone?

A
  • Breast implant-associated anaplastic large cell lymphoma
  • TEXTURED implants increase risk
  • Neither… type doesn’t matter
