Skin Cancer Risk Calculators & Personal Risk Assessment Tools
These tools assess personal and environmental risk factors such as family history, UV exposure and skin characteristics. They do not analyse photographs and do not determine whether an individual mole is cancerous. Each one is free, runs in your browser, and takes about two minutes.
Quick answer
A skin cancer risk calculator scores the risk factors you carry as a person — skin type, mole count, sunburns, sunbed use, family history and occupational UV. A mole checker analyses a photograph of one lesion. Use a risk calculator to decide how closely to watch your skin; use a photo check when a specific spot concerns you.
Choose a risk assessment
Personal Melanoma Risk Assessment
11 questions · ~2 min
Skin phenotype, mole pattern, UV history, personal and family history, age and immune status.
Best if you want the broadest personal melanoma picture.
Family History Melanoma Risk
11 questions · ~2 min
Which relatives were affected, age at diagnosis, multiple primaries, and how that interacts with your own mole pattern.
Best if a parent, sibling or child has had melanoma.
Lifetime Sun Exposure Risk
10 questions · ~2 min
Childhood sun, blistering sunburns, sunbed use, years in high-UV climates and your current protection habits.
Best if you want to know what your UV history has cost you.
Outdoor Worker Skin Cancer Risk
11 questions · ~2 min
Industry, years outdoors, peak-UV hours, reflective surfaces, workplace PPE and burn history at work.
Best if you work in construction, agriculture, delivery, utilities or maritime roles.
General Skin Cancer Risk Quiz
Short quiz · ~2 min
A quick overview across all skin cancer types rather than melanoma alone.
Best if you want the fastest general overview.
6-Cancer Risk Check
~10 min
Broader questionnaire covering breast, lung, colorectal, prostate, melanoma and cervical risk factors.
Best if you want risk factors beyond the skin.
Risk assessment vs photo-based mole checking
Risk questionnaires (this page)
Evaluate you: skin type, moles, sunburn history, family history, occupational UV. Answer questions like "am I more likely to develop melanoma?"
Photo tools
Evaluate one lesion from an image. Answer questions like "does this particular mole look concerning?" Start with the AI mole checker.
The two are complementary. A high risk-factor load never means a specific mole is cancerous, and a low one never rules a spot out.
Frequently asked questions
What is a skin cancer risk calculator?
A questionnaire that scores the background risk factors a person carries — skin type, mole count, sunburn history, sunbed use, family history, occupational UV exposure and immune status. It estimates likelihood at the level of the person, not of a specific mole.
Do these tools analyse photos of my moles?
No. These are questionnaire tools. Photo-based assessment of an individual mole or lesion is a separate ScanSkinAI product — the AI mole checker — and answers a different question.
Which risk calculator should I use?
Start with the personal melanoma risk assessment for the broadest picture. Use the family history tool if a close relative has had melanoma, the lifetime sun exposure tool if your concern is UV history, and the outdoor worker tool if your exposure is occupational.
Are they free?
Yes. Every questionnaire runs in your browser with no account, no email and no photo upload.
Can a risk calculator diagnose skin cancer?
No. None of these tools diagnose anything. They summarise recognised risk factors and point you toward an appropriate next step, which for a specific worrying spot means a photo assessment and a clinician review.
Worried about a specific spot?
Risk questionnaires cannot assess an individual lesion. If you have a mole or spot you are concerned about, use the photo-based tools instead.
