A new super-fast camera coupled with a powerful optical microscope could lead to the development of a simple blood test for cancer.
The device works by locating the circulating tumor cells (CTCs) that break away from tumors as they form in the body. Finding a tumor cell amongst all the other materials in a blood sample is a tedious process. To overcome this, a super-fast camera is used and the images then sent to a computer able to identify the cancer cells based upon their ill-defined shape.
