# How is skin cancer diagnosed?

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

## In short

A GP looks at the lesion and may refer you to dermatology. A dermatoscope is a lighted magnifier that shows structures under the skin surface. Many suspected cancers are biopsied or removed and sent to a pathologist. This is general information. Do not try to diagnose your own mole from photographs on the internet.

Photography helps you and the clinic see change. It does not replace an examination.

## What is dermoscopy?

It is a handheld microscope for skin. It helps distinguish seborrhoeic warts, blood vessels in BCC, and pigment networks in moles.

## Punch, shave or excision biopsy?

The clinic chooses a method that gets enough tissue without unnecessary scarring. Melanoma is usually excised with a margin, not shaved, when it is suspected.

## Do I need scans?

Most BCC and SCC do not. Scans are for melanoma or SCC that might have spread. Your letter will say if further tests are needed.

## Key takeaways

- Dermoscopy plus biopsy is how most skin cancers are confirmed.
- Suspected melanoma is excised, not ignored.
- Most non-melanoma cases do not need body scans.

## Frequently asked questions

### Will the biopsy leave a scar?

Usually a small one. Ask about the site and stitches before you agree.

### Can a GP freeze a suspected cancer?

Cryotherapy is for some diagnosed, low-risk lesions — not a substitute for examining a changing mole.

### Does WAN run UK dermatology clinics?

No.
