Agent-based models of cancer cells

Definition

Agent-based models of cancer cells are computational simulations that represent individual cancer cells as autonomous agents, each with its own set of behaviors and interactions. These models help researchers understand the complex dynamics of tumor growth, metastasis, and treatment responses by simulating how these agents interact in a virtual environment, allowing for the exploration of various factors influencing cancer progression.
