Clinical Correlation: Breast Exam (11/3) Flashcards
Lymphatic tissue drainage
90% ipsilateral axilla
10% internal thoracic nodes
1st site of metastasis usually
Epidemiology
1/8 lifetime risk for women
Most common cancer among women, 2nd leading cause of cancer deaths (lung)
BRCA1 and BRCA2
Family hx of breast/ovarian cancer
5-10% risk BRCA1 or BRCA2 gene (autosomal dominant)
1 - 65% BC by 70
2 - 45% risk
USPSTF: Mammography
Before 50 - individual decision w/ patient context
50-74 q2 years
Over 75 - unsure
USPSTF: BSE
Recommends against
USPSTF: CBE beyond mammography, >40yo
Evidence insufficient
USPSTF: MRI instead of mammography
Unsure
AAFP Guidelines
Recognize that recommendations do not end screening in women 40-49, just need individualized care
Guidelines similar to USPSTF (q2years mamm 50-74, not BSE, unsure 75
ACS Guidelines

Is Mastalgia risk factor?
No
Cyclic vs noncyclic breast pain
Cyclic: Diffuse, bilateral, radiates to axilla (around luteal phase - increased water in stroma)
Non: Unilateral or focal
Focal merits evaluation w/ diagnostic imaging
nipple discharge
color, number of ducts, bilateral/unilateral, associated with mass
benign in 97% cases
Physiological Discharge
Physiologic: 1yr after breast feeding, endocrinopathy, meds/drugs
Bilateral, multiple ducts, associated with nipple stimulation/breast compression, milky white
Pathological Discharge
Spontaneous, unilateral, bloody, serous, clear or associated with mass
Intraductal papilloma, ductal ectasia, carcinoma, infection
mammography and subareolar US
Cytology
Benign masses
Discrete margins, no skin changes, smooth, soft to firm and mobile
i.e. fibroadenoma, cysts
