In ablation therapy, why is it important to assess the margins of ablation?

In ablation therapy, assessing the margins of ablation is critical because it directly relates to the effectiveness of the treatment in ensuring complete destruction of the target tissue. The goal of ablation is to remove or destroy pathological tissue, such as tumors, while preserving surrounding healthy tissue. By evaluating the margins, clinicians can confirm that the entire area of the abnormal tissue has been adequately treated.

If the margins indicate that there is residual tissue left behind, it can lead to a higher risk of treatment failure, as any remaining cells may allow for the recurrence of the condition being treated. Therefore, understanding the adequacy of the ablation margins is fundamental to achieving the successful outcome of the procedure and reducing the likelihood of needing additional treatments.

While factors like recovery time, future treatment preparations, and infection risks are important in the context of a patient's overall care, they are secondary to the primary objective of ensuring that the ablation is thorough and complete.
