Screening for Breast Cancer1 Flashcards
When does the American Cancer Society recommend screening
Regular annual mammography at age 40
When does the USPSTF recommend screening mammograms?
Start at age 50 - caused controversy. Most clinicians stick to 40
Is there a set age at which mammography should be discontinued?
No. Although the USPSTF found insufficient evidence to assess additional benefits and harms of screening mammograms in women age 75 and older
What is a general rule of thumb on when to stop breast cancer screening?
If the life expectancy is less than 5 years
Women with known BRCA mutation should have breast cancer screening starting at age
25 years
Women with a strong fx for breast CA (e.g. 1st-degree relative with premenopausal breast CA) should have screening started at ナ
5-10 years before the youngest age of breast CA diagnosis in a relative
Why are brease self-examinations no longer a part of breast cancer screening regimens?
Large randomized trials failed to show any reduction in breast cancer-specific or all-causes mortality when they were used.
What % of all breast cancers are NOT visible on screening mammography?
10-20%
When should clinical breast exams be initiated?
Beginning at age 20. Repeat q 2-3 years. Annually after age 40.
Women with a high risk for breast CA should have clinical breast exams how often?
q 6 months
Screening mammography has been shown to decrease the mortality of breast cancer by:
30%
What is the difference between a screening and a diagnostic mammogram?
Screening only has the craniocaudal (CC) and mediolateral oblique (MLO) views. Diagnostic mammograms have more views and manipulations to better view the breast lesion.
What are Eklund views in mammography
AKA implant displacement views: implant is pushed back agains the chest wall and the breast is pulled over it to increase the amount of breast tissue for imaging
Should a patient with a BIRADS 5 lesion with benign pathologic findings on core needle biopsy still undergo surgical excision?
Yes
What is the BI-RADS assessment and recommendation for a category 0 lesion?
Assessment Incomplete. Rec: Need additional imaging or prior studies for comparison
