All of the following are contraindications for breast conserving surgery except –
**Core Concept**
Breast-conserving surgery (BCS) is a treatment option for early-stage breast cancer, where the tumor is removed along with a margin of healthy tissue, followed by radiation therapy. The decision to perform BCS depends on various factors, including tumor size, location, and patient preference.
**Why the Correct Answer is Right**
The correct answer is not a contraindication for breast-conserving surgery. Breast-conserving surgery can be performed in patients with small tumors, especially if they are located in the outer quadrants of the breast. In these cases, the tumor can be removed with a good margin of healthy tissue, allowing for effective treatment with radiation therapy.
**Why Each Wrong Option is Incorrect**
* **Option A:** Large tumor size is a contraindication for breast-conserving surgery because it may be difficult to remove the tumor with a good margin of healthy tissue, increasing the risk of recurrence.
* **Option B:** Multicentric breast cancer, where there are multiple tumors in different quadrants of the breast, is a contraindication for breast-conserving surgery as it may be difficult to remove all the tumors with a good margin of healthy tissue.
* **Option C:** Ductal carcinoma in situ (DCIS) is a contraindication for breast-conserving surgery if it is extensive or multifocal, as it may be difficult to remove all the abnormal cells with a good margin of healthy tissue.
**Clinical Pearl / High-Yield Fact**
When considering breast-conserving surgery, it is essential to evaluate the tumor size, location, and extent of disease to determine the best treatment option for the patient.
**Correct Answer:** D.
