Fatty liver boosts colorectal cancer spread

New research in Nature, led by Dr. Peter S. Kim, found that a fatty liver (steatosis) doesn't just make colorectal cancer worse, it directly changes how tumor cells behave, making them spread more aggressively. This isn't just a correlation; the fat cells in the liver essentially give the cancer cells a super-boost, defining how badly the disease progresses. Translation: a fatty liver makes a bad situation much, much messier for cancer patients.
