When an excision is performed, the margins refer to the edges or borders of the tissue that is removed along with the targeted lesion or tumor. Clear margins indicate that no cancerous cells are present at the edges, suggesting that the excision has successfully removed the entire abnormal area. Conversely, positive margins indicate that cancerous cells remain at the edges, which may require further treatment or re-excision. Proper assessment of margins is crucial for ensuring effective treatment and reducing the risk of recurrence.
