Free 6-Cancer Risk Check — Know Your Risk in 10 Minutes
A free, NCI/ACS-aligned questionnaire that estimates your personal risk across breast, lung, colorectal, prostate, melanoma and cervical cancers — and gives you a tailored screening plan you can actually act on. Inside the same tool you can also run a free CBC blood test cancer screen that flags pattern signals across 20+ cancers from a standard Complete Blood Count. Pair with our AI Skin Scan, Mole Checker and Report Scan for a complete preventive picture.
The 6 cancers we screen for
Together these account for roughly half of all new cancer diagnoses each year — and most are treatable when caught early.
Breast cancer
Family history, BRCA risk cues, hormonal & lifestyle factors.
Lung cancer
Smoking pack-years, radon and occupational exposures.
Colorectal cancer
Diet, BMI, family history, IBD and screening history.
Prostate cancer
Age, ethnicity, family history and PSA screening status.
Melanoma cancer
Skin type, sun exposure, mole burden, prior biopsies.
Cervical cancer
HPV status, screening history, smoking and immune factors.

Why a 6-cancer risk check matters
Roughly 1 in 2 men and 1 in 3 women will be diagnosed with cancer in their lifetime, according to global incidence data. The good news: when caught early, 5-year survival exceeds 90% for breast, prostate, melanoma and cervical cancers, and approaches 70% for early-stage colorectal disease. Almost all of that survival uplift is driven by one thing — screening at the right time, with the right test, for your specific risk profile.
That's the gap a free cancer risk assessment closes. Population-wide screening programmes (mammograms at 50, colonoscopy at 45, PSA discussions at 50) are designed for the average adult. They don't know that your mother had ovarian cancer at 42, that you smoked for 18 years, that you've had three blistering sunburns and a previous BCC, or that you've never had an HPV vaccination. Our Cancer Risk Check takes those personal signals and re-stratifies you — so high-risk individuals don't wait until the average screening age, and low-risk individuals avoid unnecessary tests.
The assessment is grounded in evidence-based frameworks: NCI (National Cancer Institute) risk factor lists, ACS (American Cancer Society) screening guidance, USPSTF recommendations, and validated calculators such as the Gail model for breast cancer and PLCOm2012-style logic for lung cancer in former and current smokers. For melanoma, we layer in Fitzpatrick skin type, lifetime sunburn count, tanning bed exposure, mole burden, and any prior dermatology biopsies you've decoded with our Report Scan. For cervical cancer, we incorporate HPV vaccination history, screening interval, smoking, and immune status.
What makes the ScanSkinAI version more useful than a one-off web quiz is integration. Your melanoma risk score isn't just a number — it's connected to every AI Skin Scan you run and every mole you log in the Mole Checker. If your skin scans flag a suspicious lesion, the system already knows you're in the high-risk tier and triages you faster. Your daily UV Forecast reminders are tuned to your Fitzpatrick type. And when you next visit a clinician, you can hand them a clean, structured printout instead of half-remembered family history.
Importantly, this is not a diagnosis and not a probability. Cancer risk modelling at the consumer level is about decision support: should I book that mammogram a year earlier? Should I push my GP for low-dose CT given my smoking history? Should I get a full-body skin check this year rather than next? The Cancer Risk Check turns those vague worries into a concrete, screening-aligned action plan — and crucially, it stays free, private, and entirely separated from any insurance system.
Take the 10 minutes. Save the result. Retake it after a lifestyle change, a new family diagnosis, or once a year. Combined with regular skin scans, decoded dermatology reports, and a sun-safe routine, it's one of the most cost-effective preventive health actions any adult can take in 2026.
CBC Blood Test Cancer Screen — 20+ cancers
A different kind of test inside the same Cancer Risk Check tool. The 6-cancer questionnaire above asks about your history. The CBC screen looks at your current blood — it takes any standard Complete Blood Count and turns it into pattern-based flags for blood, immune-system and solid-organ cancers.
Questionnaire vs CBC screen
6-Cancer Questionnaire
- • Input: your history & lifestyle
- • Output: long-term risk tier per cancer
- • Covers 6 major cancers
- • Best for: planning future screenings
CBC Blood Test Screen
- • Input: your CBC lab values
- • Output: current biological flags
- • Covers signals across 20+ cancers
- • Best for: making sense of an existing CBC
Markers analysed
- WBC total + 5-part differential
- Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils
- RBC, Haemoglobin, Haematocrit
- MCV, MCH, MCHC, RDW — red-cell shape & size
- Platelets — paraneoplastic & thrombocytosis patterns
- NLR & PLR — inflammatory cancer signals
Signals across 20+ cancers

How the CBC cancer screen works
- 1. Grab any recent CBC report. Most adults already have one from a routine check-up, pregnancy work-up or pre-op blood test. UK, EU, US units auto-detected.
- 2. Enter the values. Type in the 12–15 standard markers — about 3 minutes.
- 3. Get a pattern-based report. The screen flags combinations of values associated with specific cancer types — not just single abnormal numbers.
- 4. Take the report to your GP. Each flag includes the suggested follow-up (blood smear, ferritin, LDH, FIT, imaging, haematology referral).
What it can / cannot do
What it can do
- • Flag abnormal patterns most associated with cancer
- • Translate lab jargon into plain English
- • Compute derived ratios (NLR, PLR) automatically
- • Suggest the right follow-up test or referral
- • Give you a printable summary for your GP
What it cannot do
- • Confirm or rule out cancer
- • Replace bone-marrow biopsy, imaging or tumour markers
- • Diagnose any specific disease
- • Replace a haematologist or oncologist
- • Catch cancers that don't affect blood counts
Logic aligned with NICE NG12 (suspected cancer pathways), BSH guidance on persistent cytopenias, and peer-reviewed work on NLR/PLR as prognostic indicators in oncology. New to cancer risk screening?
