Skin cancer surgery involves removing the tumour and then reconstructing it. Depending on the size and location of the tumour the skin can either be pulled together and closed. If the skin cancer is larger and depending on the location, you might need a skin flap or graft.
A flap is tissue that is moved from an adjacent area to close the defect. Bleeding will be carefully controlled before thee wound is closed in layers. The internal layer of sutures is dissolvable whilst the outside layer is closed with non-dissolvable sutures. These will be removed a few days after the procedure. The wound is then covered with tape.
A graft is skin and sometimes cartilage that is disconnected from its blood supply and moved to a different location. It survives by in growth of blood supply from the recipient bed. Grafts need to be kept dry for 1-2 weeks depending on the location of the graft.
All scars need to be protected from the sun for about one year after surgery to prevent them getting darker. This can be with taping, sunscreen or barrier clothing as necessary.
