    Recognising a skin cancer

    Normal, healthy spots on the skin usually have a smooth edge and an even colour. Skin cancers don’t all look the same, but there are signs to look out for, including:

    • a spot that is different from other spots on the skin
    • a spot that has changed in size, shape, colour or texture
    • a sore that doesn’t heal
    • a spot that bleeds.

    There is no screening program for skin cancer, so it’s important to get to know your skin. Checking yourself every three months, or as recommended by your general practitioner (GP), will help you notice any new or changing spots.

    Skin biopsy

    If you notice any changes to your skin, your doctor will examine you, paying particular attention to any spots you have identified as changed or suspicious. If the doctor thinks you may have a skin cancer, they will usually take a tissue sample (biopsy) to confirm the diagnosis. A biopsy is a quick and simple procedure and is usually performed in the doctor’s office.

    You will be given a local anaesthetic to numb the area, and the doctor will take a small piece of tissue from the spot or cut it out completely in a procedure called an excision. Often they will use stitches to close the wound and help it heal.

    The tissue that is cut out will be sent to a laboratory, where a pathologist will examine it under a microscope. The results will be available in about a week.

    If all the cancer is removed during the biopsy, this will probably be the only treatment you need.
