Q

Fibrocystic changes big 5

A

Etiology: hormonal fluctuations cause a constellation of breast changes

Patho: cysts and fibrosis in breast tissue
H+P: mass = lumpy, tender, fluctuates with cycle
Dx: mostly clinical, imaging often not needed
Tx: nothing, if pt is symptomatic, can use hormonal therapy

Q

Fat necrosis big 5

A

Etiology: post surgery or breast injury
Epidemiology: anyone w a history of breast surgery or trauma is at risk
Patho: healing after event causes necrosis and fibrosis
H+P: mass = firm, non-tender/painless, non-mobile
Tx: none unless it is causing discomfort

Q

Galactocele big 5

A

Etiology: milk filled cyst that arises post lactation
Epidemiology: post partum women
Patho: milk retention in ducts
H+P: soft, fluctuant lump, +/- pain
Dx: US, aspriation/biopsy to confirm
Tx: usually self resolves, aspiration drainage if it doesn’t

Q

Lactation mastitis big 5

A

Etiology: lactating women usually during early lactation (4-6 weeks into breastfeeding)
Epidemiology: anyone who is lactating
Patho: ductal narrowing leads to milk retention –> swelling, edema, and inflammation, and compression of other milk ducts –> stagnant milk becomes infected with bacteria –> infection travels to surrounding breast tissue
H + P: localized swelling and pain, redness; systemic complaints = myalgia, chills, malaise
Dx: mostly a clinical dx
Tx: abx (dicloxacillin or cephalexin if no MRSA risk), continue breast feeding (gets rid of infected milk), warm compress

Q

Breast abscess big 5

A

Etiology: complication of lactation mastitis (3-11% of cases)
Patho: infected fluid retention
H+P: palpable, tender and well defined fluctuant area of breast
Dx: ultrasound
Tx: abx, US guided drainage

Q

Classifying mastalgia

A

Cyclic - changes in breast pain concordant with menstrual cycle
Non-cyclic - changes in breast pain do NOT follow menstrual cycle
Extramammary - referred breast pain from some other source (GI, MSK, pulm, etc,)

Q

Management of pt with cyclic mastalgia and no palpable mass?

A

No imaging recommended (low likelihood of cancer), enact pharmacologic (NSAIDs, Tamoxifen, Goserelin if refractory to other meds) and non-pharmacologic (counsel and educate, reduce stress and anxiety, check bra fit) interventions

Q

Management of a pt with noncyclic mastalgia and no palpable mass?

A

If pain is FOCAL:
- Targeted US in pts under 30
- Diagnostic mammo AND targeted US if pt is > 30

If pain is NONFOCAL:
- No imaging if pt is < 40 OR has no risk factors
- Diagnostic mammo if pt > 40 OR has risk factors

Q

T or F: Normal imaging rules out any mass or other abnormality

A

False, sometimes masses go undetected on imaging

17
Q

Characteristics of a malignant mass

A
  • Irregular border
  • Solid
  • Non mobile
  • Heterogenous on imaging
  • round
  • dimpling of overlying skin
  • associated lymphadenopathy
  • bloody discharge
18
Q

Characteristics of benign masses

A
  • Solid OR cystic
  • Regular borders
  • Mobile
  • Homogenous on imaging
19
Q

What are the 2 main imaging modalities for breast lumps?

A

US and mammogram

20
Q

When do you use US vs mammogram?

A

US – used in pts < 30
mammogram - used in pts > 40

pts in between 30 and 39 can use either

21
Q

What imaging modality CONFIRMS a breast lump diagnosis?

A

Breast biopsy (aka aspiration)

22
Q

BIRADS scoring interpretation (used to score breast lumps)

A

0 = incomplete; get more imaging
1 = negative findings; no additional imaging necessary unless high clinical suspicion for abnormal finding
2 = benign; resume routine screening
3 = probably benign; short interval clinical f/u
4 = suspicious abnormality; biopsy + specialist referral
5 = high cancer risk (>95%); biopsy + urgent specialist referral
6 = confirmed cancer; ensure adequate treatment

23
Q

Imaging flow for pt with palpable breast mass

A

Under 30 = start with targeted US, over 40 = start with mammogram –> if lesion is not visualized, mammogram if not yet done, or biopsy

24
Q

What is BIRADS used for?

A

Used to figure out management of a breast mass with a confirmed lesion on biopsy

BIRADS 1 or 2: clinical f/u (if cystic lesion/solid lesion w/ no sx), aspiration (if solid lesion w/ sx)

BIRADS 3-5: biopsy to determine next steps
