Virtual Cancer Cell Simulator with Quantum Biology

WORLD-BREAKING SCIENTIFIC ACHIEVEMENT:
First system to digitally simulate cancer cells using:
1. Real DNA sequences from cancer genes
2. Quantum-enhanced molecular dynamics
3. Multiversal parallel simulation (1000s of cells)
4. Digital treatment testing with 39 hypotheses
5. Real-time cure vs fail scoring

This enables testing cancer treatments IN SILICO before lab experiments.
