Study reveals cancer grows uniformly across tumors, challenging previous beliefs about its spread.

Researchers from the University of Cologne and the Centre for Genomic Regulation found that cancer grows uniformly throughout a tumor, not just at the edges. This discovery challenges old beliefs about cancer growth and spread. By analyzing genetic information in liver tumors, they observed mutations spread evenly, suggesting all parts of the tumor are actively growing. This could explain how cancer cells evolve to evade the immune system. The study, published in eLIFE, used spatial genomics technology and computer simulations to map the tumor's growth patterns. Further research is needed to understand larger and metastatic tumors.
