How common viruses could quietly raise your cancer risk

In this episode of Science Quickly, one of SciAm’s Young American Scientists, biologist Jaye Gardiner, explores how common viral infections may raise cancer risk—not just through genetic mutations but by reshaping the body’s “extracellular matrix” of molecules that support cells and tissues. She explains how viruses can alter the extracellular matrix, potentially creating conditions that allow tumors to grow, and why this emerging view could change how we think about everything from colds to long COVID.
