Wide local excision removes a tumour together with a margin of normal tissue around it. It is commonly used for skin cancers, melanoma, soft-tissue tumours and some other solid tumours. The width of the margin depends on the cancer type and thickness.

The pathologist examines the edges of the specimen. If cancer is found at the margin, further surgery may be advised. Larger defects may need a skin graft or flap to close.

How the Procedure Can Help

It removes the cancer completely, lowering the risk of local recurrence.

Risks and Considerations

Possible effects include scarring, wound infection, delayed healing and numbness. Re-excision may be needed if margins are not clear.
