Surgical Margins

Surgical margins refer to the border or edge of tissue removed during surgery to ensure complete removal of a disease, such as cancer. The goal is to leave no abnormal or cancerous cells behind. If the margins are "clear," it means no cancer is seen at the outer edge of the removed tissue, suggesting all the disease has been excised. If the margins are "positive," cancer cells are found at the edge, indicating some may remain and additional treatment might be needed. Proper margins are crucial for reducing the risk of the disease returning.
