# Skin cancer signs: sores that do not heal

> Source: World Aid Network — https://worldaidnetwork.org/cancer/skin-cancer/symptoms

## In short

Skin cancer is the UK’s most common cancer, with more than 350,000 cases a year. Most are non-melanoma — basal cell or squamous cell — caused by UV from the sun or sunbeds. Look for a sore that will not heal, a new lump, or a scaly patch.

Non-melanoma skin cancers are rarely life-threatening when treated. Melanoma has its own silo. Both are largely preventable by not burning.

## What should you show a GP?

Take a photo if a patch changes. GPs can refer to dermatology on a suspected-cancer pathway.

- A new growth, lump or patch that will not heal
- A sore that scabs, bleeds and does not heal in a few weeks
- A mole that changes (see the melanoma ABCDE rule)
- A rough, scaly or crusty patch, especially on sun-exposed skin

## BCC or SCC — what is the difference?

Basal cell carcinoma is the most common and rarely spreads. Squamous cell carcinoma can spread if neglected. Both are treated, usually with surgery, in dermatology clinics.

## How do you cut UV risk?

Shade, clothing, and sunscreen on uncovered skin. Do not use sunbeds. A tan is skin injury, not health.

## Key takeaways

- A sore that will not heal should be checked.
- UV is the main cause.
- Most non-melanoma skin cancers are highly treatable.

## Frequently asked questions

### Do I need a whole-body mole map?

People with many moles or a strong family history may be offered surveillance. Everyone should report a changing lesion.

### Can skin cancer appear where the sun does not shine?

Yes, though sun-exposed sites are more common. Check your back, scalp and between the toes.

### Do you fund skin cancer surgery overseas?

When a partner hospital can treat an eligible patient who cannot pay.
