| Age | Height | Weight | Smoking | Pack-years | Alcohol/wk | Activity/wk | Processed meat/wk | Fruit & veg/day | Family history | UV | Screening | Occupational | BMI | Score | Band |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

Formula used
This calculator uses a normalized weighted score:
Each factor is scaled from 0.00 to 1.00, then multiplied by its weight. The weights below add to 100 points.
| Factor | Weight | How it is interpreted |
|---|---|---|
| Age | 12 | Older age increases baseline weighting in this educational model. |
| Body mass index | 8 | Higher BMI bands add more points. |
| Smoking and pack-years | 18 | Current smoking and greater cumulative exposure add the most points. |
| Alcohol use | 8 | More weekly drinks raise the factor score. |
| Physical activity | 8 | Lower weekly movement produces higher points. |
| Processed meat intake | 8 | More weekly servings raise diet-related weighting. |
| Fruit and vegetable intake | 6 | Lower daily servings reduce protective scoring. |
| First-degree family history | 12 | A positive history adds strong non-modifiable weighting. |
| Sun and UV exposure | 6 | More exposure increases skin-related risk weighting. |
| Screening status | 8 | Being overdue or unsure adds points because missed screening may delay detection. |
| Occupational exposure | 6 | Possible or known hazardous exposure increases weighting. |
The result is a general awareness score, not a validated prediction model for any single cancer type.

Frequently asked questions
1) Is this calculator a diagnosis?
No. It is an educational composite score. It cannot confirm cancer, rule it out, or replace medical testing, screening, or clinician judgment.
2) What does a higher score mean?
A higher score means more weighted risk markers are present in this model. It suggests a stronger prevention focus, not a guaranteed outcome.
3) Why is family history included?
First-degree family history can shift baseline risk. Including it helps flag when a clinician may need a fuller history or earlier screening discussion.
4) Why does screening status affect the score?
Being overdue does not cause cancer directly. It matters because delayed screening can reduce chances of catching some cancers earlier.
5) Can lifestyle changes lower the score?
Yes. Quitting smoking, reducing alcohol, improving diet, increasing activity, managing weight, and staying current with screening can lower modifiable burden.
6) Does this apply to every cancer type?
No. This is a broad wellness score. Different cancers have different drivers, screening rules, and inherited risk patterns.
7) Should younger adults ignore the result?
No. Younger adults often have lower baseline weighting, but lifestyle, family history, and exposure patterns still matter for prevention planning.
8) When should I speak with a clinician?
Speak with a clinician for symptoms, strong family history, unusual exposures, or overdue screening. Urgent symptoms should not wait for online tools.
