Most lesions are benign, but it is always worth checking them out and Dr Dancey will do this without charge as part of a consultation or treatment. Any lesions that you don’t like and are benign can be shaved off, such as warts, sebaceous keratoses (dry aging spots), small moles. Flat lesions such as brown marks and sun spots can be peeled off using electrocautery. Lesions that are potentially nasty can be referred back to your GP or to a specialist.
