Breakthrough Study Challenges Long-Held Cancer Growth Theories
New research from the University of Cologne and the Centre for Genomic Regulation challenges the long-held belief that tumors grow faster at their edges. Using spatial genomics and computer simulations, scientists found that liver tumors grow uniformly throughout their mass, with evenly distributed mutations. This discovery, published in eLife, suggests that tumors are not 'two-speed' entities and highlights the complexity of tumor evolution and therapy resistance. The study's findings, while focused on liver cancer, may not apply to all cancer types and primarily address early-stage tumor growth.
