Key Information:

When we talk about skin cancer, most people think of melanoma and checking moles. However, the vast majority of skin cancers in the UK are actually non-melanoma skin cancer.

This page covers the two most common types: Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC).

Type 1: Basal Cell Carcinoma (BCC)

This is the most common type of all skin cancers. It is usually very slow-growing.

Appearance: It can look like a small lump that is pearly or waxy, or sometimes like a flat, scaly patch.

The "Stubborn Spot": A very common sign is a sore that seems to heal up but then breaks down again. Think of it as a stubborn spot that just won't properly go away.

Risk: The good news is that a BCC almost never spreads to other parts of the body, but it does need to be treated to remove it completely.

Type 2: Squamous Cell Carcinoma (SCC)

This is the second most common type. It can grow a bit more quickly than a BCC.

Appearance: It often appears as a firm red lump, or a flat patch with a scaly, crusty surface.

Sensation: It may feel tender and can sometimes bleed easily if you catch it.

Risk: The risk of spreading is still very low, but it is slightly higher than with a BCC. Getting it seen and treated early is important.

The 4-Week Rule

The most important takeaway for any type of skin cancer is the timeline.

• Is New; AND
• Does not heal properly within 4 weeks; OR
