Will a biopsy of a small lesion on the nose always leave a scar?

I tell my patients that anytime we cut the skin, it will leave a scar. Whether that scar is noticeable to most people will depend on the type of biopsy taken (shave vs punch biopsy) and how deep the biopsy needs to be. Lesions concerning for skin cancers such as melanoma will need to be deeper than other biopsies and may leave a more noticeable scar.

Any time there is a removal done, there is a potential for a small mark or scar. Following good post care will minimize this very much, so please ask your dermatologist for the best post care to follow. "This answer has been solicited without seeing this patient and cannot
