Novel imaging technique shows promise in breast cancer

A breakthrough imaging approach using terahertz waves enabled clear visualization of ductal carcinoma in situ lesions smaller than 0.5 mm and had nearly thousandfold greater accuracy in distinguishing DCIS and invasive ductal carcinoma samples without the need for tissue sample staining, compared with other terahertz-based techniques, according to a study to be published in the Journal of Physics: Photonics. "Combining our technique with machine learning will aid in the early detection of cancer and determination of cancer malignancy, as well as the development of innovative terahertz diagnostic devices using micro electromechanical systems," said researcher Masayoshi Tonouchi.
