About 80% of breast cancer biopsies turn out benign – new imaging tool promises clearer diagnoses and fewer biopsies

My work as an engineer focuses on improving imaging technology to detect and diagnose cancer. Breast cancer grows when the tumors form new blood vessels and consume more oxygen. This makes examining blood vessels and oxygen levels potential biomarkers that could improve breast cancer diagnosis. Diffuse optical tomography, or DOT, is an imaging technology that uses near-infrared light to measure total blood hemoglobin concentration and oxygen levels – key indicators of tumor activity – in the breast lump. It does not require patients to be injected with contrast dyes to make the image clearer.
