Question 1.
Which breast structure is responsible for milk production?
A. Lactiferous sinus
B. Lobules
C. Nipple
D. Cooper’s ligaments
Answer: B
Rationale: Lobules contain glandular acini that produce milk. Lactiferous
sinuses store milk, the nipple delivers milk, and Cooper’s ligaments provide
structural support.
Question 2.
The most common anatomical site for breast cancer development is the:
A. Upper outer quadrant
B. Lower inner quadrant
C. Subareolar region
,D. Upper inner quadrant
Answer: A
Rationale: The upper outer quadrant contains the most glandular tissue and
the axillary tail of Spence, making it the most frequent site for breast cancer.
Question 3.
BRCA1 and BRCA2 mutations are associated with increased lifetime risk of which
cancers?
A. Breast and ovarian cancer
B. Lung and colon cancer
C. Thyroid and skin cancer
D. Pancreatic cancer only
Answer: A
Rationale: BRCA mutations significantly increase the risk of breast, ovarian,
fallopian tube, and peritoneal cancers; BRCA2 also raises male breast and
prostate cancer risk.
Question 4.
The standard screening imaging tool for average risk women aged 40 and older
is:
,A. Breast ultrasound
B. Breast MRI
C. Mammography
D. Thermography
Answer: C
Rationale: Mammography is the primary screening modality for early
detection, reducing breast cancer mortality. Ultrasound and MRI are
supplemental in specific populations.
Question 5.
A 35 year old woman with a palpable breast mass should initially undergo:
A. Screening mammogram only
B. Diagnostic mammogram and targeted ultrasound
C. Breast MRI
D. Core needle biopsy
Answer: B
Rationale: Diagnostic mammogram and ultrasound are first line imaging for a
palpable mass in women under 40; biopsy follows if imaging is suspicious.
, Question 6.
Core needle biopsy reveals atypical ductal hyperplasia (ADH). The appropriate
next step is:
A. Routine follow up
B. Surgical excisional biopsy
C. Bilateral mastectomy
D. Tamoxifen chemoprevention alone
Answer: B
Rationale: ADH on core biopsy requires surgical excision to rule out coexisting
ductal carcinoma in situ (DCIS) or invasive cancer, as upgrade rates approach 15
30%.
Question 7.
Sentinel lymph node biopsy uses which combination for identification?
A. Methylene blue dye only
B. Radioactive colloid and/or blue dye
C. Indocyanine green fluorescence only
D. Ultrasound guided aspiration
Answer: B
Rationale: The dual agent technique (technetium 99m sulfur colloid and
isosulfan blue or methylene blue) increases the accuracy of sentinel node
identification.
