Tumor Progression

Tumor progression refers to the process by which cancer cells grow, change, and become more aggressive over time. Initially, abnormal cells multiply abnormally, forming a small tumor. As these cells evolve, they may invade nearby tissues and potentially spread to other parts of the body through the bloodstream or lymphatic system. This progression often results in increased tumor size, complexity, and difficulty in treatment. Understanding tumor progression helps medical professionals develop strategies to detect, monitor, and treat cancers effectively at different stages.
