Quick answer
UK skin cancer risk is driven mainly by intermittent intense UV exposure (holiday sun and sunbeds), fair skin (Fitzpatrick I–II), high mole count or atypical moles, personal or family melanoma history, and immunosuppression. The most modifiable factor is sunburn — particularly blistering burns in childhood. Anyone in a higher-risk group should add a monthly home self-check with dated photos to their annual GP visit. ScanSkinAI is a screening and monitoring tool, not a diagnosis.
TL;DR: Key Takeaways
- UK melanoma incidence has more than doubled since the 1990s
- Intermittent intense sun (holidays, sunbeds) is more risky than steady exposure
- Fair skin, many moles, family history = closer monitoring
- Sunbeds before 35 raise melanoma risk by ~75% (WHO/IARC)
- Modifiable lever #1: avoid sunburn. Lever #2: monthly self-checks
Who is at higher risk?
- Fitzpatrick skin types I–II (very fair to fair, burns easily)
- History of any blistering sunburn — especially in childhood
- More than 50 moles, or any atypical (dysplastic) moles
- Personal or first-degree family history of melanoma
- Sunbed use (any age, but especially before 35)
- Immunosuppression — organ transplant, certain medications
- Outdoor occupation with chronic sun exposure (NMSC risk especially)
Why one check is rarely enough
A single scan tells you about one spot, on one day. But skin changes are about patterns over time — a new mole appearing, a slow shift in shape, size or colour, or a patch that simply isn't healing. Monitoring the same spots side-by-side, week after week, surfaces the subtle changes a one-off check will always miss — and gives you a clear record to show a clinician if something needs a closer look.

What you can actually change
- Daily SPF 30+ during UV index 3+ days (UK March–September)
- Cover up between 11 am and 3 pm on holidays
- Never use a sunbed — full stop
- Treat every blistering sunburn as a long-term flag for monitoring
- Monthly self-checks if you fall into any higher-risk group

Family history and genetics
Roughly 10% of melanomas occur in patients with a family history. First-degree relatives of someone with melanoma have approximately double the risk. A small proportion of high-risk families carry pathogenic CDKN2A or BAP1 mutations — eligible for NHS genetics referral if there are three or more affected relatives, or any family member with multiple primary melanomas.
- 1 affected first-degree relative: ~2x risk
- 2+ affected first-degree relatives: ~4–5x risk · consider dermatology surveillance
- 3+ relatives or any with multiple primaries: NHS clinical genetics referral
- Personal history of melanoma raises risk of a second primary by ~5–10x
Environmental and lifestyle factors
- Latitude — higher UV closer to the equator; long-haul holidays multiply lifetime UV dose
- Altitude — UV intensity rises ~10–12% per 1,000 m (skiing burns)
- Reflective surfaces — snow reflects up to 80% of UV, water and sand 10–25%
- Occupational sun exposure — outdoor workers carry chronically elevated NMSC risk
- Vitamin D and sun: most UK adults can meet vitamin D needs via short non-burning exposure or supplementation — burning is never required
A simple risk-band summary
Use this as a personal triage:
- Average risk: no risk factors → annual self-awareness + monthly photo of any worrying mole
- Moderate risk: one or two risk factors → monthly self-checks + annual GP review
- High risk: multiple factors, family history or atypical moles → monthly self-checks + 6-monthly dermatology + total-body photography
- Post-melanoma: per oncology follow-up schedule, typically 3-monthly for first 1–2 years
