10 Free Breast Practice Questions

1. What blood vessel supplies the medial inner breast?

   1. Circumflex artery
   2. Subclavian artery
   3. Axillary artery
   4. Internal thoracic artery
   Show Answer & Explanation

   Correct answer: Internal thoracic artery

   The internal thoracic artery supplies oxygenated blood to the medial inner segment of each breast.

2. What are the glands called that lubricate the areola?

   1. Spencer's glands
   2. Montgomery's glands
   3. Cooper's glands
   4. Supramammary glands
   Show Answer & Explanation

   Correct answer: Montgomery's glands

   Montgomery's glands are the glands that lubricate the areola of the breast.

3. The presence of two mammary glands on one side of the body describes which congenital anomaly?

   1. Amazia
   2. Polymastia
   3. Macromastia
   4. Amastia
   Show Answer & Explanation

   Correct answer: Polymastia

   Polymastia is when there is >1 mammary gland on each side of the body (i.e., two breasts on the right or left). It is described as supernumerary breast tissue.

4. How accurate is ultrasound in the differentiation of a cystic versus solid lesion of the breast?

   1. >96%
   2. <15%
   3. 70-76%
   4. 40-52%
   Show Answer & Explanation

   Correct answer: >96%

   Ultrasound is between 96- and 100% accurate in differentiating between a cystic versus solid lesion. For this reason, ultrasound is often used as a supplemental tool alongside screening mammogram for further characterization of atypical findings.

5. The most optimal imaging of the breast can be achieved through the use of which transducer?

   1. 10.0 MHz linear array
   2. 18.0 MHz curvilinear array
   3. 6.0 MHz linear array
   4. 3.0 MHz curvilinear array
   Show Answer & Explanation

   Correct answer: 10.0 MHz linear array

   The patient’s breast size should be considered when selecting the transducer frequency to yield an appropriate resolution to penetration ratio. A 10.0 MHz or higher transducer provides the best resolution for the small-to-average sized breast, while the frequency may need to be lowered slightly (i.e., 8.0 MHz) for the larger-chested patient. Breast imaging is standardly performed using a linear transducer.

6. In patients greater than 40 years of age, what imaging test is the gold standard for routine breast cancer screening?

   1. Mammogram
   2. Ultrasound
   3. MRI
   4. CT
   Show Answer & Explanation

   Correct answer: Mammogram

   An annual mammogram is widely accepted for malignancy screening, with modalities such as ultrasound and MRI as an accessory to differentiate cystic from solid structures (i.e., US) or in the presence of breast implants (i.e., MRI).

7. Which segment of the breast ducts is lined with epithelial cells?

   1. Epithelial cells are not present within breast ducts
   2. Middle
   3. Inner
   4. Outer
   Show Answer & Explanation

   Correct answer: Inner

   Epithelial cells line the inner part of breast ducts.

8. Which sign correlates to intracapsular implant rupture?

   1. Noose
   2. Linguini
   3. Stepladder
   4. Snowstorm
   Show Answer & Explanation

   Correct answer: Stepladder

   Visualizing the stepladder sign is the most reliable finding of intracapsular rupture in a silicone gel breast implant via ultrasound.

9. Which abnormality or syndrome involves sclerosing superficial thrombophlebitis of the anterior thoracic wall veins?

   1. Marfan's disease
   2. Peau d'orange
   3. Fibrocystic breast
   4. Mondor disease
   Show Answer & Explanation

   Correct answer: Mondor disease

   This disease involves thrombophlebitis of the veins in the chest/breast tissues.

10. Which of the following is the gold standard imaging examination for Ductal carcinoma in situ (DCIS)?

    1. Mammogram
    2. Ultrasound
    3. MRI
    4. CT
    Show Answer & Explanation

    Correct answer: Mammogram

    Ductal carcinoma in situ (DCIS) typically presents as suspicious microcalcifications which may be present with or without a coinciding mass. Suspicious microcalcifications on breast imaging are typically characterized by shape and distribution, suspicious shape raise concerns about their potential association with malignancy, these include: Amorphous, Coarse heterogeneous, Fine Pleomorphic, Fine linear or fine-linear branching microcalcifications. For this reason, mammography is the gold standard imaging test for DCIS.
