Micrima’s Mission

To reduce the number of women who die of breast cancer by developing a system that can aid earlier detection.

About Us

The whole team at Micrima come to work every day because we believe there has to be a better way to detect this disease earlier and prevent some of these deaths. Our mission is to continue to work with clinicians and technical experts, in house and external, to develop a breast imaging system that is comfortable for the patient, easy to interpret and can be used frequently and from a much younger age in order to detect breast cancer.
