Precision Oncology Tumor Matching Simulator

Precision medicine's clearest win is molecular tumor profiling: sequence the tumor's DNA, find its actionable driver mutation, and pick the drug built for exactly that alteration. This simulator visualizes a tumor as a population of cells growing under logistic competition for space and nutrients, then lets you choose the tumor's driver mutation (EGFR, HER2 or BRAF V600E) and a therapy to challenge it with — a targeted drug that only works when it matches the tumor's real mutation, an immunotherapy whose effect scales with tumor mutation burden, or a mutation-agnostic chemotherapy fallback. Watch the population, response rate and a proxy circulating-tumor-DNA level evolve week by week as the mismatch — or match — between mutation and therapy plays out.
