Question

Explanation:

When removing margins around a tumor during surgery, the main goal is to get rid of any remaining cancer cells. Metamorphosis is not relevant here. Ensuring patient comfort is a general aspect but not the main objective of removing tumor margins. Confirming diagnosis is usually done through biopsy before or during surgery (not the main purpose of margin removal).

Answer:

eliminating residual cancer cells
