Skin Cancer Risk Factor Calculator
Tally common skin-cancer risk factors — skin type, sunburns, family history, tanning beds and mole count — into a simple awareness score.
How it works
Score = fair-skin points + sunburn-history points + family-history + tanning-bed + high-mole-count (0–9)
The strongest known risk factors for skin cancer include fair skin that burns easily, a history of blistering sunburns, tanning-bed use, many moles, and a family history of the disease. This tool simply counts those factors so you understand your relative exposure — it is an awareness aid, not a screening test. A higher tally means being more vigilant about sun protection and getting professional skin checks; a lower tally is not a guarantee, since anyone can develop skin cancer.
Worked example
A fair-skinned person (type II, 1 point) with three blistering burns (2), no family history (0), past tanning-bed use (2) and normal mole count (0) scores 5 of 9 — the moderate band, a nudge toward diligent sun protection and self-exams.
Frequently asked questions
Does a low score mean I am safe?
No. These are risk factors, not a diagnosis or a screen. People with dark skin and few risk factors still get skin cancer — often diagnosed later — so everyone should protect their skin and watch for changes.
What is the ABCDE rule?
It flags worrying moles: Asymmetry, irregular Borders, uneven Colour, Diameter over about 6 mm, and Evolving (changing) spots. Any of these, or a sore that will not heal, warrants a dermatologist visit.
How often should high-risk people get checked?
People with several risk factors or a personal or family history often have professional skin exams yearly or more, plus monthly self-exams. Your dermatologist sets the right interval.
