본문내용

2. Risk factor for breast cancer
(1) major
①sex(F>M)
②Age(30대 이후부터 40,50 대에 peak)
③Family Hx.
④Personal Hx(contralat. breast ca.)
⑤Noninvasive carcinoma(ductal or lobular CIS)
⑥Benign proliferative change with atypia

(2) minor
①early menarch
②Late menopause
③Obesity
④Low-does radiation

*prophylactic sugical Tx(either subcutaneous or total mastectomy in the setting of a positive family history): mother & sister가 bilat. ca. at early age

3. Diagnosis
1) Biopsy
(1) palpable mass: FNA, core Bx, excisional Bx, incisional Bx
(2) non-palpable mass: stereotactic Bx, NLB

*Criteria for open Bx
①needle aspiration produce no cystic fluid and a solid mass is diagnosed
②the cyst fluid produced is thick and blood tinged
③Fluid is produced but the mass fails to resolve completely
④the mass reapperars in the same area
⑤Rapid accumulation of fluid after initial aspiration(2wk)

4. BI-RADS
1) Incomplete
* Category 0
2) Complete final categories
* Category 1 negative
* Category 2 benign finding
* Category 3 probably benign finding
* Category 4 suspicious abnormality
: Biopsy should be considered.
4A: low suspicious for malignancy
4B: intermediate suspicion of malignancy
4C: moderate concern, but not classic for malignancy
* Category 5 highly suggestive of malignancy (> 95%)
* Category 6 known biopsy-proven malignancy
