bining CARS and intravital flow cytometry represents a possible new diagnostic tool to screen patients for cancer. The tool can be used to count lipid-rich tumor cells circulating in a patient's blood by shining a laser through the skin and into blood vessels. Because lipids can be detected without the need for dyes, the technique might be developed into a convenient method to diagnose whether a patient's cancer is spreading aggressively, Cheng said.

"These findings open the possibility of an entirely new, relatively simple method for diagnosing whether cancer is metastasizing," he said.

Future work will focus on not only how obesity increases metastasis but also how it might play a direct role in initiating the development of cancers.
