How to detect skin cancer early

The best way to detect skin cancer early is to look for it regularly.

If you’re familiar with your own skin, you can notice new or changing spots or lumps. For the spots you don’t notice, have a skin check with an experienced doctor or skin cancer clinician.

Check your skin regularly

Skin cancers usually appear as “ugly duckling” spots, most commonly appearing on normal skin.

You don’t need special training to detect an ugly duckling; it can be bigger, darker, lighter, differently-shaped, rougher or different from the other spots in many different ways.

You identify them by comparing them with the surrounding spots. If you notice a new or changing outlier or “odd one out”, it might be a skin cancer – you should have it checked by a doctor.

Tips to detect skin cancer

If you're familiar with your own skin, you can notice new or changing spots or lumps. For the spots you don’t notice, have a skin check with an experienced doctor or skin cancer clinician.

Tips to detect skin cancer
Photograph your moles to keep track of them

Using your phone and the MoleScope app, you can record what your skin looks like at any given time. The app allows you to photograph:

  • Individual spots of interest.
  • Regions of your body (i.e. you can perform your own mole mapping at home).

Once you’ve photographed your moles or body regions a few times, you can compare them side-by-side on your computer to see if there are any odd-looking new spots or changes to existing ones.

The MoleScope app also allows you to send photos to one of our doctors for an opinion if it’s not possible for you to attend the clinic.

Have regular checks with your skin cancer doctor

About half of the melanomas detected in Australia are discovered by health workers examining patients who were unaware of the melanoma’s presence. Without an examination, these melanomas may have been present for much longer before they were noticed by the patient, their partner, a friend or a family member. This delay in diagnosis could potentially allow the melanoma time to spread to other parts of the body, leading to serious illness.

When a doctor, nurse or other skin cancer clinician checks your body, they use a dermoscope, allowing them to see fine details beneath the skin’s surface. These details assist in skin cancer detection earlier than possible without dermoscopic examination.

If you’re at risk of skin cancer, you should consider having your skin examined every year.
