Lipid-Rich Cancer Cells (IMAGE) Purdue University Caption Researchers at Purdue have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals. Here, lipid-rich cancer cells (the two round objects) attach to collagen fibrils, simultaneously visualized using coherent anti-Stokes Raman scattering and sum frequency generation imaging. Cancer cells attach to collagen before spreading to organs in the body.
