Shown is an optical mammography image of hemoglobin oxygenation of a duct carcinoma in situ (DCIS), a breast cancer in the lining of the milk ducts that has not yet invaded nearby tissues. In this image, the boxed area corresponds to the cancer location and indicates lower values of hemoglobin oxygenation.
For cancerous tissue that is associated with abnormal hemoglobin concentration and oxygenation, optical mammography can be used to help diagnose breast cancer and also indicate how well a patient responds to breast cancer chemotherapy.
