Cancer Risk Prediction

AI-Powered Screening Tool · 9 Machine Learning Models

⚕️This tool is for screening purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.

Model Guide — Which Should I Use?

⭐ HighRecall_Ensemble — Recommended

Best for screening. Combines 4 models with boosted minority-class weights to catch the most cancer cases. Lowest false-negative rate.

🥈 Ensemble_L2_ET — Strong Runner-Up

Logistic + ExtraTrees soft-vote. Better precision than the top model — fewer false alarms.

📐 SVM — Highest AUC (0.931)

Best at ranking patients by risk score. Use for risk stratification rather than binary decisions.

📊 Logistic Models — Most Explainable

L1 (feature selection) and L2 (stable coefficients). Best when transparency and interpretability matter.

Prediction Model

HighRecall_Ensemble is recommended for most users.

Enter 0 if not applicable.

Systolic Blood Pressure (mmHg)

Upper BP reading. Normal: <120 | Elevated: 120-129 | High: >=130

Diastolic Blood Pressure (mmHg)

Lower BP reading. Normal: <80 | High: >=80

Risk Assessment

Binary result based on the model's tuned decision threshold.

Cancer Risk Probability (%)

Model's estimated probability of cancer (0-100%). Values above the threshold = HIGH RISK.

Decision Threshold

Per-model cutoff tuned on validation data. Above this = HIGH RISK.
