On a sunny March morning in Bengaluru, Ayesha Banu and Noorunnisa walk up to the stage of Nitte Meenakshi Institute of Technology. Their white canes folded and held aside, they speak to a packed hall of students and teachers about their work as Medical Tactile Examiners (MTEs). We assist doctors in detecting the early signs of breast cancer in women," Banu speaks into the mic. "Using the first two fingers of both hands, we examine women's breasts for abnormalities." She explains that blind women like herself and Noorunnisa are especially well-suited to this profession because of the "high tactile sense in our fingertips, which helps us find tiny lumps in the breast." Tactile breast examinations, or TBEs, are clinical breast examinations specially designed for blind women trained as MTEs. Employing MTEs for routine breast cancer screening " and reaching women in their communities and workplaces " could help in the early detection of cancer and save lives, says Dr. Poovamma CU, the breast specialist under whom Banu and Noorunnisa work. Studies prove that in the absence of sight, blind people's brains can develop a heightened sense of touch, as well as hearing. Through the MTE training, a woman with vision impairment is able to empower another woman, by offering her preventive health care. In a recent Indian study where two MTEs conducted TBEs on 1,338 women, their success rate of detecting malignant cancers was over 78 percent, and the miss rate, only one percent.
