Removal (excision) or biopsy of a skin lesion
Tangohanga, whakamātaunga pokanga rānei o te taotūtanga ā-kiri
A skin biopsy is when a health professional removes a small part of a skin lesion for testing. A lesion is an area of damaged skin, like a mole, freckle or spot.
Excision is when the whole lesion is removed.
In both cases, the skin is sent to the laboratory, where a specialist examines it under a microscope to find out whether it is cancerous.
Many GPs are specially trained to remove skin lesions, so often your own doctor may be able to treat you. The cost of biopsy and excision varies between doctors and the type and size of the lesion. You may be eligible for a subsidy to reduce the cost of the procedure. Talk to your general practice team about this.
If your GP is not trained in removing skin lesions or thinks your lesion is more complicated, they can refer you to another doctor who specialises in this procedure. This could be another GP who does skin excision surgery, or Minor Surgery at Burwood Hospital.
A small number of people with skin cancer are suitable for Mohs surgery. Mohs surgery (or Mohs micrographic surgery) is a specialised technique. You may wish to pay to see a GP with special interest in skin surgery, private plastic surgeon or a private dermatologist about this. You can find a private dermatologist on Healthpoint.
