Navigate complexity

AI struggles with:

• Patients with multiple conditions
• Unusual symptom presentations
• Context that affects treatment decisions
• Ethical considerations in care

AI in specific medical areas

Cancer detection and treatment

Current applications:

• Analyzing biopsy images
• Detecting tumors in scans
• Predicting treatment responses
• Personalizing treatment plans

The reality: AI assists oncologists but doesn’t replace the complex decision-making in cancer care.

Heart disease

Current applications:

• Analyzing ECG readings
• Predicting heart attack risk
• Monitoring patients remotely
• Detecting irregular heartbeats

The reality: AI helps catch problems earlier, but cardiologists make treatment decisions.

Diabetes management
