What is removed during an excision biopsy?

During an excision biopsy, the procedure involves the complete removal of the lesion along with a margin of normal tissue surrounding it. This approach ensures that not only the lesion is removed, but that any potentially affected adjacent tissue is also excised. This is crucial for accurate pathological assessment and minimizes the risk of leaving behind cancerous cells or other abnormalities.

In many cases, especially with suspected malignancies, a complete excision helps in providing a definitive diagnosis and reduces the chances of recurrence by addressing the surrounding area where abnormal cells might be present. Therefore, this method enhances the effectiveness of treatment and contributes to better patient outcomes.
