Non-Melanoma Skin Cancer: The Most Common Types

Key Information

Common and Treatable: Most skin cancers in the UK are non-melanoma skin cancers, not melanoma.
The Main Types: The two most common types are Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC).
The Key Rule: Any new spot that does not heal within 4 weeks should be checked.

This page explains the typical features of the two most common non-melanoma skin cancers:

Type 1: Basal Cell Carcinoma (BCC)
- This is the most common type of all skin cancers and 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 common sign is a sore that seems to heal but then breaks down again — a spot that just will not properly go away.
- Risk: A BCC almost never spreads to other parts of the body, but it does need treatment to remove it completely.
Type 2: Squamous Cell Carcinoma (SCC)
- This is the second most common type and can grow more quickly than a BCC.
- Appearance: 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 caught.
- Risk: The risk of spreading is still low, but slightly higher than with a BCC. Early treatment is important.
