A treatment called carbon dioxide (CO2) laser therapy can be used to treat small melanomas that come back in the same area (recurrent melanoma). It may also be used for advanced melanoma to help shrink the melanoma and to help with symptoms such as pain or bleeding.
It involves directing a high-intensity beam of light at the affected areas of skin to destroy the melanoma cells.
You can have this treatment as an outpatient. You can have it more than once. You may be given a local anaesthetic to numb the area first. You may feel some discomfort in the skin during and after treatment. Taking mild painkillers can help. The area may be covered with a dressing to protect it afterwards.
