Q&A: Your Top Skin Cancer Questions Answered

We asked our Skin Institute clinicians to answer the most common questions about skin cancer that patients often ask. Here are their expert insights:

1. What’s the difference between a mole and melanoma?
A mole is a common, usually harmless skin growth made up of pigment-producing cells. A melanoma is not a mole but a type of skin cancer that can arise either from an existing mole or appear as a new spot. Warning signs include asymmetry, irregular borders, varied colours, diameter over 6mm, or changes over time.

2. Can skin cancer show up in places not exposed to the sun?
Yes. While sun exposure is the biggest risk factor, skin cancer can develop anywhere — including the soles of your feet, under nails, or even between your toes. Regular full-body skin checks are crucial.

3. How often should I get a skin check?
For most people, an annual skin check is recommended. However, if you have a personal or family history of skin cancer, fair skin, or lots of moles, you may need checks every 6 months. Book in a skin cancer consultation to find out more and always get any new or changing spots reviewed immediately.

4. What does a skin cancer consultation involve?
One of our trained Skin Cancer clinicians will examine your skin from head to toe using a dermatoscope (a specialised skin microscope). The process is painless and non-invasive.

5. If I wear sunscreen daily, do I still need a check?
Absolutely. Sunscreen lowers your risk but doesn’t eliminate it. Prevention and early detection work best together.
