Now I have a rich set of verified, textbook-backed content. Let me compile the comprehensive PYQ-style question bank for Breast topic.

🏥 Breast - High-Yield PYQs (NEET PG / INICET / UPSC / SMS)

Compiled from recalled exam questions, textbook sources (Schwartz, Sabiston, Bailey & Love, Current Surgical Therapy, Fischer's), and pattern analysis.

SECTION A: ANATOMY & PHYSIOLOGY

Q1. The axillary tail of the breast is also known as:

A) Tail of Haversian
B) Tail of Spence ✅
C) Tail of Rathke
D) Tail of Comet

Schwartz's Surgery: The breast extends from 2nd to 6th rib, sternum to mid-axillary line, with an axillary extension - the axillary tail of Spence - into the axilla.

Q2. What percentage of breast lymphatic drainage goes to axillary lymph nodes?

A) 50%
B) 65%
C) 75%
D) 85% ✅

Current Surgical Therapy 14e: "The axillary lymph nodes receive 85% of the lymphatic drainage from the breast."

Q3. The predominant route of lymphatic drainage of the breast is to:

A) Internal mammary nodes
B) Supraclavicular nodes
C) Axillary nodes ✅
D) Infraclavicular nodes

SECTION B: BENIGN BREAST DISEASE

Q4. Most common benign breast tumor in young females (15-30 years):

A) Phyllodes tumor
B) Lipoma
C) Fibroadenoma ✅
D) Cystosarcoma phyllodes

Key fact: Fibroadenoma is hormone-sensitive, may enlarge in pregnancy. It is well-circumscribed, mobile ("breast mouse"). Small typical ones can be observed.

Q5. "Breast mouse" refers to:

A) Phyllodes tumor
B) Fibroadenoma ✅
C) Lipoma
D) Galactocele

Q6. Phyllodes tumor differs from fibroadenoma in all EXCEPT:

A) Older age group
B) Rapid enlargement
C) Axillary lymph node metastasis is common ✅
D) May be malignant

Schwartz's: Axillary dissection is NOT recommended for phyllodes because axillary lymph node metastases rarely occur. The answer that is INCORRECT about phyllodes is that ALND is commonly indicated.

Q7. Treatment of malignant phyllodes tumor of breast:

A) Wide local excision
B) Mastectomy ✅
C) Modified radical mastectomy with ALND
D) Lumpectomy + radiotherapy

Large/malignant phyllodes: mastectomy WITHOUT axillary dissection (lymph node mets rare).

Q8. Drug-induced gynecomastia is seen with all EXCEPT:

A) Spironolactone
B) Cimetidine
C) Finasteride
D) Furosemide ✅

Drugs causing gynecomastia: spironolactone, cimetidine, antiandrogens, anabolic steroids, digoxin, metoclopramide, ketoconazole. Furosemide is NOT classically listed.

SECTION C: CARCINOMA BREAST - STAGING & CLASSIFICATION

Q9. (INICET 2025 Recall) A patient presents with a rapidly growing breast lump (20×15 cm), erythema, and peau d'orange with family history of breast cancer - diagnosed as inflammatory breast cancer. Appropriate treatment is:

A) Neoadjuvant chemotherapy followed by MRM ✅
B) MRM followed by chemotherapy
C) Neoadjuvant therapy followed by BCT and SLNB
D) Palliative care

Schwartz's: IBC (Stage IIIB) - neoadjuvant chemotherapy (anthracycline-based) → assess response → Modified Radical Mastectomy → adjuvant therapy + chest wall/nodal irradiation. Note: The DigiNerve INICET 2025 recall listed answer as "C" (neoadjuvant + BCT) but the textbook standard for IBC is neoadjuvant chemo → MRM. BCT is NOT standard for IBC.

Q10. Hallmark histological finding of inflammatory breast carcinoma is:

A) Lymphocytic infiltrate
B) Tumor emboli in dermal lymphatics ✅
C) Squamous metaplasia
D) Comedonecrosis

Sabiston: "Hallmark of inflammatory breast cancer is diffuse tumor involvement of the dermal lymphatic channels within the breast and overlying skin."

Q11. (NEET PG recall) A breast cancer with skin changes involving >1/3rd of breast skin, acute onset erythema, and peau d'orange - stage is:

A) T3
B) T4a
C) T4b
D) T4d ✅

T4d = Inflammatory breast cancer (peau d'orange involving ≥1/3 of breast skin, acute onset within 3 months).

T4a = chest wall fixity

T4b = skin edema/ulceration

T4c = both T4a and T4b

T4d = inflammatory carcinoma

Q12. Peau d'orange (orange-peel skin) in breast cancer is due to:

A) Dermal lymphatic obstruction ✅
B) Venous obstruction
C) Arterial invasion
D) Skin infiltration by cancer cells

Robbins Pathology: "Infiltration and obstruction of superficial lymphatics by breast cancer may cause edema of the overlying skin; the characteristic finely pitted appearance is called peau d'orange."

Q13. Inflammatory breast cancer accounts for what percentage of all breast cancers?

A) <3% ✅
B) 5-10%
C) 10-15%
D) >20%

Schwartz's: <3%; Current Surgical Therapy 14e: ~2% in the USA.

SECTION D: SURGICAL MANAGEMENT

Q14. Sentinel lymph node biopsy was first described/developed in:

A) 1984
B) 1990
C) 1994 ✅
D) 2000

Current Surgical Therapy: "The development of sentinel lymph node biopsy in 1994 has been groundbreaking to the management of the axilla."

Q15. As per ACOSOG Z0011 trial, completion axillary lymph node dissection can be omitted in:

A) Any node-positive patient
B) T1-T2 tumors with clinically node-negative disease undergoing lumpectomy with 1-2 positive sentinel nodes ✅
C) T3 tumors with 1 positive sentinel node
D) Mastectomy patients with positive sentinel nodes

Current Surgical Therapy: Z0011 - patients with T1-T2, clinically node-negative, undergoing lumpectomy, with 1-2 positive sentinel nodes → completion ALND can be omitted with no difference in overall survival.

Q16. AMAROS trial compared in node-positive patients (positive SLNB):

A) SLNB vs. ALND
B) ALND vs. axillary radiotherapy ✅
C) Chemotherapy vs. radiotherapy
D) Lumpectomy vs. mastectomy

Current Surgical Therapy: AMAROS - ALND vs. axillary radiation in SLNB-positive patients. No difference in OS, but ALND had 2-fold higher lymphedema (40% vs. 22% at 1 year).

Q17. Immediate breast reconstruction is contraindicated in:

A) DCIS
B) T2 tumors
C) Inflammatory breast cancer ✅
D) BRCA mutation carriers

Sabiston: "Immediate breast reconstruction is contraindicated in breast cancers with aggressive pathology, such as inflammatory breast cancer, because reconstruction may delay postmastectomy radiation treatment."

Q18. In male breast cancer, treatment is:

A) Mastectomy only
B) Similar to female breast cancer - breast conservation with axillary staging + RT, or mastectomy with axillary staging ✅
C) Always modified radical mastectomy
D) Hormonal therapy alone

Fischer's Mastery of Surgery: "Surgical management of male breast cancer involves similar options to that of female breast cancer."

SECTION E: RECEPTORS & MOLECULAR BIOLOGY

Q19. Triple negative breast cancer (ER-, PR-, HER2-) - best response to neoadjuvant chemotherapy is seen in which molecular subtype?

A) Luminal A
B) Luminal B
C) Triple negative ✅
D) HER2 enriched

Current Surgical Therapy: "Response to neoadjuvant therapy...is greatest in triple-negative and HER2-positive tumors."

Q20. Sentinel lymph node mapping can be done using all EXCEPT:

A) Blue dye (isosulfan blue / methylene blue)
B) Technetium sulfur colloid radiotracer
C) Indocyanine green (ICG)
D) Gadolinium-based contrast ✅

Blue dye, Tc-99m sulfur colloid, ICG - all used. Gadolinium is an MRI contrast agent, not used for SLNB mapping.

SECTION F: SPECIAL SITUATIONS (HIGH-YIELD)

Q21. Paget's disease of the nipple is associated with underlying carcinoma in what percentage?

A) 10%
B) 30%
C) >90% ✅
D) 50%

Paget's disease = eczematoid change of nipple - >90% have underlying carcinoma (DCIS or invasive). Never dismiss as eczema without biopsy.

Q22. Bloody nipple discharge is MOST commonly associated with:

A) Fibroadenoma
B) Intraductal papilloma ✅
C) Breast carcinoma
D) Duct ectasia

Most common cause of unilateral, bloody nipple discharge = intraductal papilloma. Cancer must be excluded.

Q23. DCIS (Ductal Carcinoma In Situ) surgical options include:

A) Only mastectomy
B) Breast-conserving surgery (partial mastectomy) as part of BCT, or mastectomy ✅
C) Lumpectomy alone without radiotherapy
D) Chemotherapy only

Mulholland & Greenfield's: "Surgical options for treatment of DCIS include breast-conserving surgery as a component of breast conservation therapy (partial mastectomy + RT), or mastectomy."

Q24. All women should undergo breast cancer risk assessment by age:

A) 25
B) 30
C) 35 ✅
D) 40

Mulholland & Greenfield's: "All women should undergo risk assessment by age 35 to determine the best approach for breast cancer screening."

Q25. In clinically node-positive breast cancer, axillary management is:

A) Sentinel lymph node biopsy only
B) Axillary lymph node dissection (level I and II) ✅
C) Observation
D) Radiotherapy alone

Current Surgical Therapy: "For women with clinically positive axillary lymph nodes confirmed by FNA or core needle biopsy...ALND may be performed. Level I and II anatomic LND is preferred."
