What Does Skin Cancer Look Like?

Introduction

Skin cancer is the most common form of cancer in Australia, but the good news is that early detection saves lives. The challenge is that skin cancer doesn’t always look the same; it can show up as a new spot, a changing mole, or even a sore that doesn’t heal. So, what does skin cancer actually look like?

In this article, we’ll cover the key signs to watch for, including the ABCDE guide to melanoma, and explain when you should see your doctor.

Common Signs of Skin Cancer

Not all skin cancers look alike, but there are some common features to keep in mind:

• Basal Cell Carcinoma (BCC): Often appears as a shiny, pearly bump, or a red patch that may bleed easily.
• Squamous Cell Carcinoma (SCC): Usually forms as a scaly, crusted sore or a thickened patch of skin that may be tender.
• Melanoma: The most serious type, often starts as a mole that changes in size, colour, or shape.

The ABCDE Rule for Melanoma

One of the best tools for spotting dangerous moles is the ABCDE rule:

• A – Asymmetry: One half looks different to tother.
• B – Border: Edges are irregular, blurred, or jagged.
• C – Colour: Uneven shades of black, brown, red, or even blue.
• D – Diameter: Larger than 6mm (about the size of a pencil eraser).
• E – Evolving: Changing in size, colour, or shape.

If a mole or spot shows any of these warning signs, it’s important to get it checked promptly.

Can Skin Cancer Appear in Hidden Places?

Yes. While most skin cancers appear on sun-exposed areas like the face, ears, arms, and legs, they can also develop in less obvious spots, including:

• The soles of the feet
• Under fingernails or toenails
• The scalp
• Genital areas

This is why full-body skin checks are so important.

When to See a Doctor

You should see a doctor if you notice:

• A new mole or spot that looks unusual
• A sore that won’t heal
• A mole that bleeds, itches, or crusts
• Any change in an existing mole

Early diagnosis usually means simpler treatment and a higher chance of cure.

Key Takeaway

Skin cancer doesn’t always look the same, but by following the ABCDE rule and staying aware of changes, you can catch problems early. If you’re ever unsure about a mole or spot, it’s better to get it checked.
