Canadian chip could gauge breast estrogen with a needle poke
University of Toronto researchers unveil a lab on a chip that uses digital microfluidics to extract and measure estrogen from tiny breast tissue samples obtained by needle. The device aims to enable quick, routine monitoring of estrogen levels to track therapy response and cancer risk, though years of study remain before clinical use. The approach moves from traditional blood tests to direct breast measurements, potentially transforming breast cancer care and infertility monitoring.
