An Excision Biopsy is a surgical procedure used to remove an entire lump or abnormal area in the breast for detailed examination. It is commonly recommended when imaging or needle biopsy results are inconclusive or if a complete removal of a suspicious lesion is necessary.

During the procedure, the affected area is removed along with a margin of surrounding healthy tissue to ensure accurate diagnosis. The tissue is then sent to a laboratory for histopathological analysis to determine whether the lesion is benign (non-cancerous) or malignant (cancerous).

This biopsy is performed under local or general anesthesia, depending on the size and location of the lesion. The procedure usually takes about 30 to 60 minutes. A small scar may remain, but efforts are made to minimize its visibility, often using oncoplastic techniques to maintain the natural shape of the breast.

Excision biopsy plays a crucial role in the early detection and diagnosis of breast cancer and can also serve as a therapeutic procedure when the lesion is completely removed.
