A NEW pocket-sized device may allow doctors to check a woman's breast cancer risk in minutes with just droplets of blood or a sliver of breast tissue, according to Canadian researchers.
They said the microchip device can measure levels of the hormone estrogen using far smaller samples than conventional methods, making it possible to quickly screen for breast cancer risk or check to see if treatments are working.
"The new device is compatible with extremely small samples - around 1,000 times smaller than the amount needed for conventional analyses," said Aaron Wheeler of the University of Toronto, whose study appears in the journal Science Translational Medicine.
