Benign Breast Diseases Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Benign Breast Diseases. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Benign Breast Diseases Indian Medical PG Question 1: Which of the following breast lesions is associated with the HIGHEST risk of developing invasive breast cancer?
- A. Sclerosing adenosis
- B. Simple fibroadenoma
- C. Florid hyperplasia
- D. Atypical hyperplasia (Correct Answer)
Benign Breast Diseases Explanation: ***Correct: Atypical hyperplasia***
- **Atypical hyperplasia** (either atypical ductal hyperplasia [ADH] or atypical lobular hyperplasia [ALH]) represents a proliferative lesion with some, but not all, features of carcinoma in situ [1]
- Associated with a **4-5 times greater risk** of developing invasive breast cancer compared to the general population
- Characterized by disordered architectural patterns and cellular atypia, indicating a **significant increased risk** for future malignancy [1]
- Considered a high-risk lesion requiring close surveillance
*Incorrect: Sclerosing adenosis*
- This is a **benign proliferative lesion** characterized by increased glandular elements and stromal fibrosis
- Confers only a **slightly increased risk (1.5-2 times)** of breast cancer
- While it can sometimes mimic carcinoma on imaging, it is generally considered a **low-risk lesion**
*Incorrect: Simple fibroadenoma*
- A **simple fibroadenoma** is a benign tumor composed of both glandular and stromal tissue
- **Does not increase the risk** of breast cancer
- Typically presents as **well-circumscribed, mobile masses** and is among the most common benign breast lesions
*Incorrect: Florid hyperplasia*
- Also known as **usual ductal hyperplasia without atypia**
- Involves an increase in the number of epithelial cells within the ductal lumen but lacks cellular atypia
- Carries a **minimal increased risk (1.5-2 times)** for developing invasive breast cancer
- The absence of atypia distinguishes it from the higher-risk atypical hyperplasia

Benign Breast Diseases Indian Medical PG Question 2: ACR score 4 in breast imaging indicates
- A. Probably benign
- B. Highly suggestive of malignancy
- C. Negative
- D. Suspicious abnormality (Correct Answer)
Benign Breast Diseases Explanation: ***Suspicious abnormality***
- An **ACR BI-RADS category 4** indicates a **suspicious abnormality** that necessitates a biopsy to rule out malignancy.
- The risk of malignancy in this category ranges from **2% to 94%**, representing findings that do not have the classic appearance of malignancy but have a definite probability of being cancer.
*Probably benign*
- This description corresponds to an **ACR BI-RADS category 3**, which suggests a less than 2% chance of malignancy.
- Category 3 findings are usually followed up with **short-term interval imaging** (e.g., 6 months) to assess stability.
*Highly suggestive of malignancy*
- This corresponds to an **ACR BI-RADS category 5**, where the findings almost certainly represent **malignancy** (at least 95% probability).
- Category 5 lesions require **appropriate action**, such as biopsy or definitive treatment, based on the highest level of suspicion.
*Negative*
- This description is for an **ACR BI-RADS category 1**, meaning there are **no significant findings** and the breast is normal.
- Category 1 indicates that the study is completed and no further action is needed beyond routine screening.
Benign Breast Diseases Indian Medical PG Question 3: Gold standard investigation for breast carcinoma screening in a patient with silicone breast implants
- A. Mammography
- B. CT scan
- C. USG
- D. MRI (Correct Answer)
Benign Breast Diseases Explanation: ***MRI***
- **MRI** is considered the **gold standard** for breast cancer screening in patients with silicone breast implants due to its superior ability to visualize breast tissue through the implant and detect subtle lesions.
- It offers **high sensitivity** in detecting both implant rupture and early malignancies, often providing better clarity than mammography in augmented breasts where implants can obscure tissue.
*Mammography*
- While a standard screening tool, **mammography** can be limited in patients with silicone implants because the implants can **obscure adjacent breast tissue**, making detection of small masses challenging.
- Special views (e.g., **Eklund views**) can be used, but sensitivity is still reduced compared to MRI in augmented breasts.
*CT scan*
- **CT scans** are not routinely used for primary breast cancer screening due to their use of **ionizing radiation** and lower sensitivity for detecting early breast lesions compared to MRI.
- CT is more commonly used for **staging** advanced cancers or evaluating complex masses detected by other modalities.
*USG*
- **Ultrasound (USG)** is a valuable complementary tool, especially for evaluating palpable lumps or clarifying findings from mammography, but it is **operator-dependent** and has a lower overall sensitivity for general screening compared to MRI.
- It is particularly useful for differentiating between **cystic and solid masses** and detecting implant ruptures but is not the gold standard for comprehensive screening in augmented breasts.
Benign Breast Diseases Indian Medical PG Question 4: On mammogram, all of the following are the features of a malignant tumor except:
- A. Microcalcification
- B. Irregular mass
- C. Macrocalcification (Correct Answer)
- D. Spiculation
Benign Breast Diseases Explanation: ***Macrocalcification***
- **Macrocalcifications** are typically **benign** and are often associated with involutional changes in the breast, such as aging or fibroadenomas.
- These are usually larger, coarser calcifications that are easily seen and rarely indicate malignancy.
*Microcalcification*
- **Microcalcifications**, especially when **pleomorphic**, **linear**, or grouped, are a significant indicator of potential malignancy, such as **ductal carcinoma in situ (DCIS)**.
- They represent calcium deposits within the ducts or stromal tissue, which can be associated with rapidly proliferating cells.
*Irregular mass*
- An **irregularly shaped mass** with ill-defined margins is highly suspicious for malignancy because it suggests invasive growth into surrounding tissues.
- Unlike benign lesions which tend to be round or oval with smooth borders, malignant tumors often grow in an uncontrolled, infiltrative manner.
*Spiculation*
- **Spiculation** refers to **radiating lines or projections** extending from the borders of a mass, indicating an infiltrative process highly suggestive of malignancy.
- These spicules represent fibrous tissue reaction to an invading tumor and are a strong predictor of breast cancer.
Benign Breast Diseases Indian Medical PG Question 5: A microbiology laboratory reports growth of Staphylococcus aureus from pus drained from a breast abscess. What is the most likely condition predisposing the patient to the development of a breast abscess?
- A. Endocarditis
- B. Menopause
- C. Breast feeding (Correct Answer)
- D. Inflammatory breast carcinoma
Benign Breast Diseases Explanation: ***Breast feeding***
- **Lactation** is the most common predisposing factor for breast abscesses, as **milk stasis** and **cracked nipples** can lead to bacterial entry and infection.
- *Staphylococcus aureus* is the most frequent pathogen isolated in **lactational mastitis** and subsequent abscess formation.
*Endocarditis*
- Endocarditis is an infection of the **heart valves** and, while it can cause septic emboli, it is not a direct predisposing factor for a localized breast abscess.
- The primary symptoms of endocarditis are usually systemic, such as fever, new heart murmurs, and embolic phenomena, which are not described here.
*Menopause*
- Menopause involves hormonal changes that can affect breast tissue but typically does not predispose women to acute bacterial breast abscesses.
- Postmenopausal breast infections are less common and often associated with duct ectasia or other benign conditions rather than acute abscesses from *Staphylococcus aureus*.
*Inflammatory breast carcinoma*
- Inflammatory breast carcinoma can mimic infection with redness and warmth, but it is a **malignancy** and does not directly predispose to a bacterial abscess.
- While it can sometimes be superimposed on an infection or cause skin changes that increase infection risk, it is not the most direct predisposing condition for a *Staphylococcus aureus* abscess.
Benign Breast Diseases Indian Medical PG Question 6: Inflammatory carcinoma of the breast is classified under which category?
- A. T4b
- B. T4c
- C. T4d (Correct Answer)
- D. T3
Benign Breast Diseases Explanation: ***T4d***
- **Inflammatory carcinoma of the breast** is specifically classified as **T4d** in the TNM staging system, regardless of tumor size.
- This classification reflects its unique clinical presentation with **diffuse erythema, edema, and peau d'orange** (orange peel skin) due to lymphatic invasion [1].
*T4b*
- **T4b** refers to breast cancer with clinically evident **edema, ulceration of the skin of the breast**, or satellite skin nodules in the same breast [2].
- While inflammatory carcinoma might have edema, the hallmark features of widespread erythema and lymphatic involvement distinguish T4d.
*T4c*
- **T4c** is used when a tumor exhibits **both T4a and T4b features**.
- **T4a** involves chest wall fixation, and T4b involves skin edema/ulceration; neither specifically defines inflammatory breast cancer [2].
*T3*
- **T3** classifies breast tumors larger than **5 cm in greatest dimension** but without features of T4.
- Inflammatory breast cancer is defined by its characteristic skin changes and lymphatic involvement, not solely by tumor size.

Benign Breast Diseases Indian Medical PG Question 7: Which of the following conditions is not typically treated with a simple mastectomy?
- A. Paget's disease
- B. Fibroadenoma (Correct Answer)
- C. Cystosarcoma phyllodes
- D. None of the options
Benign Breast Diseases Explanation: ***Fibroadenoma***
- A **fibroadenoma** is a **benign tumor** of the breast that typically does not require a mastectomy for treatment.
- Treatment usually involves **observation**, **excision**, or **cryoablation**, depending on size, symptoms, and patient preference.
*Paget's disease*
- **Paget's disease of the breast** is a rare form of breast cancer that affects the nipple and areola, and is typically associated with an underlying **ductal carcinoma in situ** (DCIS) or **invasive breast cancer**.
- Due to the presence of malignancy and its superficial spread, **mastectomy** (simple or modified radical) is often the recommended treatment, especially for extensive disease.
*Cystosarcoma phyllodes*
- Formerly known as **phyllodes tumor**, this is a rare **stromal tumor** of the breast that can be benign, borderline, or malignant.
- Due to its potential for local recurrence and, in malignant cases, metastasis, **wide local excision with clear margins** is crucial, and a **simple mastectomy** may be necessary for large or recurrent tumors to achieve adequate margin control.
*None of the options*
- This option is incorrect because fibroadenoma is a condition not typically treated with a simple mastectomy, unlike Paget's disease and cystosarcoma phyllodes.
Benign Breast Diseases Indian Medical PG Question 8: In a patient presenting with jaundice, the HIDA scan would be most useful for which of the following:
- A. Biliary atresia (Correct Answer)
- B. Cholelithiasis
- C. Benign biliary disease
- D. Bile duct carcinoma
Benign Breast Diseases Explanation: ***Biliary atresia***
- A **HIDA scan** (hepatobiliary iminodiacetic acid scan) is instrumental in diagnosing biliary atresia by demonstrating the **absence of bile flow** into the duodenum.
- In infants with persistent jaundice, the failure of the tracer to appear in the small bowel after a prolonged period strongly suggests this condition, indicating **obstructed or absent bile ducts**.
*Cholelithiasis*
- While HIDA scans can detect **cystic duct obstruction** in acute cholecystitis, they are less definitive for uncomplicated cholelithiasis (gallstones without acute inflammation).
- **Ultrasound** is typically the primary imaging modality for diagnosing gallstones due to its non-invasiveness and ability to visualize stones directly.
*Benign biliary disease*
- This is a broad category, and while a HIDA scan can assess bile flow, it's not the **primary diagnostic tool** for all benign biliary conditions.
- For most benign biliary diseases (e.g., choledocholithiasis without acute cholecystitis), **ultrasound, ERCP, or MRCP** often provide more detailed anatomical information.
*Bile duct carcinoma*
- A HIDA scan might show **obstructed bile flow** in bile duct carcinoma (cholangiocarcinoma), but it does not provide the detailed anatomical information or staging necessary for diagnosis and treatment planning.
- **CT, MRI, MRCP, or ERCP** with biopsy are far more effective for identifying, characterizing, and staging bile duct malignancies.
Benign Breast Diseases Indian Medical PG Question 9: A 43 year old woman presented with serous discharge from a single duct of the nipple of her right breast which was sent for evaluation. She is unlikely to be suffering from
- A. Intraductal Papilloma
- B. Fibrocystic disease (Correct Answer)
- C. Carcinoma
- D. Duct Ectasia
Benign Breast Diseases Explanation: ***Fibrocystic disease***
- **Fibrocystic changes** usually present with **lumpy breasts**, pain, and sometimes **multiple** duct nipple discharge, which can be clear or milky.
- A **single duct serous discharge** is not a typical presentation, making it less likely given the details.
*Intraductal Papilloma*
- **Intraductal papilloma** is the **most common cause** of **serous or bloody nipple discharge** from a **single duct**.
- This benign tumor grows within the milk ducts and is a frequent finding with the described symptoms.
*Carcinoma*
- **Ductal carcinoma in situ (DCIS)** or **invasive ductal carcinoma** can present with **unilateral, bloody or serous nipple discharge** from a **single duct**.
- The type of discharge and its unilateral, single-duct nature are concerning features that warrant malignancy exclusion.
*Duct Ectasia*
- **Duct ectasia** can cause nipple discharge which is often **thick, sticky, and multicolored** (green, black, or brown), and may be associated with **nipple inversion**.
- While it can be from a single duct, the discharge is typically **not serous** and is more characteristic of a **dilated or inflamed duct**.
Benign Breast Diseases Indian Medical PG Question 10: A 17 year old girl presents with an ovarian cyst of 5cm. The cyst is echo free, unilocular and CA 125 of 8U/ml. What is most appropriate management?
- A. Laparoscopy for cyst removal
- B. Conservative with follow up ultrasound (Correct Answer)
- C. Laparotomy for cyst removal
- D. Medical treatment
Benign Breast Diseases Explanation: ***Conservative with follow up ultrasound***
- A 5cm **unilocular, echo-free ovarian cyst** in a 17-year-old with a normal **CA-125** (8 U/mL is well within the normal range, typically <35 U/mL) is highly suggestive of a **benign functional cyst**.
- Expectant management with **serial ultrasound follow-up** is the most appropriate initial approach, as these cysts often resolve spontaneously.
*Laparoscopy for cyst removal*
- This is an **invasive procedure** that is not indicated for a likely benign, asymptomatic ovarian cyst, especially given the young age of the patient.
- Surgical intervention would only be considered if the cyst persists, grows significantly, causes symptoms, or shows suspicious features on imaging.
*Laparotomy for cyst removal*
- **Laparotomy** is an even more invasive surgical approach than laparoscopy, involving a larger incision, and is reserved for cases where malignancy is strongly suspected or for very large, complex cysts that cannot be removed laparoscopically.
- Given the benign characteristics of the cyst, this approach is unwarranted.
*Medical treatment*
- There is **no specific medical treatment** (e.g., medication) that effectively resolves functional ovarian cysts.
- While hormonal contraceptives can sometimes suppress the formation of new functional cysts, they do not typically treat an existing one of this nature.
