Benign skin lesion is an umbrella term for a range of lumps and bumps including moles, cysts, keratoses, skin tags, calluses, corns and warts. They are generally harmless and do not necessarily need to be removed unless you do not like the way they look.
Following consultation and skin assessment Treatment will depend on the size of the lesion, how deep it is and where it is on your body. Benign skin lesion removal takes place under local anaesthetic.
Shave excision the lesion off at its base so it is at the level of the surrounding skin. This may be combined with a technique called cautery which seals the skin and stops bleeding. This method is used for lesions such as keratosis, skin tags and ‘shallow’ moles.
Excision Complete removal, where the entire lesion is surgically removed. Your surgeon will remove the lesion and some of the tissue around it and you may need stitches afterwards. This is a technique used for larger moles or for lesions which are suspected to be cancerous.
Freezing (which involves freezing off the lesion with liquid nitrogen). Also known as cryotherapy it can be used to remove warts, skin tags and keratosis. The liquid nitrogen is applied to the lesion for about 10 seconds. A blister will form which, when it falls off, will take the lesion with it. We do not offer this treatment at the centre currently.
