Obesity Rewires Tumor Environment to Accelerate Breast Cancer Invasion

At the University of Oklahoma, researchers have uncovered something more unsettling than a statistical correlation: obesity does not merely raise the odds of breast cancer, it rewires the biological logic by which early tumors become invasive ones.
