What are smooth cancer margins?

Smooth cancer margins refer to the edges of a tumor that are well-defined and free of cancerous cells upon examination after surgical removal. This indicates that the surgery successfully excised the tumor with a clear boundary, minimizing the likelihood of residual cancerous tissue left behind. In contrast, irregular or infiltrative margins may suggest that cancer cells could remain, potentially increasing the risk of recurrence. Smooth margins are generally associated with a better prognosis.
