Breast radiologists as OperatorsOur special considerations/challenges
Technical/operative:-choice of modalities
-lesion location
-visibility
-breast thickness
-contraindications uncommon
-complications uncommon
Radiologic/rad-path:-”false positive”
-false negative—don’t forget!
-did you get the lesion?
-deciding when done
-follow up imaging or excise?
-patient preferences!
-potential loss to follow up (importance of direct communic)

Case 2
JYL2019 9
Case 2–Q
31 year old white woman (average risk) presents with a new right palpable lump x 1 month. She does do periodic self-breast exam (SBE). Which tests to use and in which order?
A. Nothing needed. Average risk. Likely benign anyway.
B. Breast ultrasound only, because of radiation risk. Maybe biopsy and clip, then do mammo.
C. Straight to palpation guided core biopsy or excision. More efficient.
D. Bilateral diagnostic mammo and ultrasound. Biopsy as indicated by imaging
JYL2019 10
Case 2– Answer
She is 31, of average risk, presenting with a new palpable lump. Which tests and in which order?
For over 30, usually start with mammography--balance risk and benefit. Comparison breast is helpful and makes exam complete.
Ultrasound and biopsy as indicated by imaging and clinical details.
But art of medicine, can start with ultrasound too as in this case.

Diagnostic ultrasoundLooking for correlate for mammofinding
Is this a match?
What next?
Did we look everywhere else, bilaterally, including axilla?
What next?
If 2D + screening US +dense BT, then which modality gets credit for cancer detection?
17
JYL2019
Biopsy?
Which method?
US-core biopsy=IDC involving radial scar…
What next?What if radial scar alone?
18
JYL2019
What if she had had screening ultrasound last year?
Have supplemental screening ultrasound data proved mortality benefit?
Will it ever?
And so what?

Case 3–Q
Spiculated mass on screening mammo. Workup and biopsy showed “invasive ductal carcinoma involving a radial scar.” Is this concordant? What is next management step?
A. BI-RADS 6, concordant. Rec surgical and oncologic management
B. BI-RADS 3, because the IDC is in a radial scar so doesn’t really count. Rec imaging follow up.
C. BI-RADS 4, because the IDC might be a false positive. The RS might be a false positive too. Rec surgery for more info.
D. BI-RADS 2, because IDC might be a false positive. And RS is not cancer. High risk lesions are benign. Rec routine imaging.
E. BI-RADS 0, need more information. Rec surgery.
JYL2019 20
Case 3– Answer
Spiculated mass on screening mammo. Workup and biopsy showed “invasive ductal carcinoma involving a radial scar.” Is this concordant and what is next management step?
A. BI-RADS 6, concordant. Rec surgical and oncologic management
Disc: spiculated mass ddx includes malignancy and “false positives” such as radial scar and fat necrosis (that would be benign and concordant). Cancer -> surgery but in many institutions, so might RS because it’s a high risk lesion, and may be associated with cancer at time of detection. The so called “upgrade potential” at surgery.

• Concordant…and benign…so far…?
• Patient traveling so opts out of excisional biopsy for full histopath…
• Not all HRLs go straight to excision—balance clinical and shared decision making
• Short term follow up imaging (STFU)—only effective if the patient does follow through with the follow up.Make sure she’s informed of results, and aware of the why the f/u

Case 5 -- sidestepping the FPsPt anxiety…how about rads’ anxiety?
Television celebrity, 62y
Eager to do an October breast awareness month feature
Wants to do live mammo appt and live reading of her exam
Yes, +fam hx
Not sure when was last exam or where…
JL is the breast imager to see her
JL made multiple requests for any outside prior exams…meeting resistance due to their rush timing
JL declined request to interpret exams on “live camera”
Finally got OSF on day of filming:
10/14, 9/12, 2/11, 10/08, 10/07

Screening mammo: 62 year old woman with strong fam hx. New to your institution. What would you like to do next?
A. Dense breasts, fam hx supplemental screening US
B. Breast MRI. More sensitive than screening US.
C. I see a clip. There are calcs. Need a biopsy.
D. Right exaggerated CC lateral, for partially seen asymmetry
E. Compare with prior outside films and path records. Everything I can get. And complete this exam.

You’ve compared with the prior two years. Convinced of a developing asymmetry at lumpectomy site. What to do next?
A. Rec surgical excision. This is highly suspicious.
B. Rec stereotactic guided biopsy. This is suspicious.
C. Do ultrasound, correlate. Anticipate US finding to guide biopsy. Left axilla, full ultrasound—would be good.
D. Do MRI next. US will be nonspecific. Not sure about biopsy.

Summary
• The science and the art of medicine
• Best practices, appropriateness criteria… but we’re doctors with real intelligence, not artificial intelligence
• Smartly using all the tools we got
• SBE and CBE count too (espinterval CAs, not screening)
• Dense breasts: Not all dense breasts get cancer. Cancers arise in all density levels.
• Masking potential is the more immediate concern.
• “False positives”- get those OSF to avoid the avoidable FPs
• “False positives”- the unavoidable kind.
