Will a lump on scalp indicating 99% benign skin lesion require complete excision?
This is not serious.
Thank you for the query.
It would be much easier to answer this query if you attach a photo of it.
From your description there is no reason to be worried. Your lump is for 99% benign skin lesion. Freezing it is not a good idea. It has to be removed completely otherwise it will regrow.
Please consult general surgeon and consider removal of this lump. This is simple and most effective solution.
Hope this will help. Feel free to ask further questions.
