About

Scientific research attributes a significant percentage of cancer cases to modifiable lifestyle factors. While genetics play a role, choices regarding diet, physical activity, and substance use often weigh heavily on long-term health outcomes. This assessment tool utilizes epidemiological data to generate a simplified "Risk Score". It highlights areas where behavioral changes-such as smoking cessation or weight management-can statistically lower the probability of developing malignancies.

The scoring logic aggregates weighted vectors from user inputs. This is a simplified linear model:

Score = wsmoke + wbmi + walc + wdiet
