A program trains women as tactile medical examiners to identify tumors before they show up on imaging scans. And, in a materials science discovery, scientists made a liquid silk solution that hardens and picks up objects—not unlike Spider-Man’s web.How Blind Women In India Are Detecting Early Breast CancerBreast cancer is the second most common cancer worldwide, just behind lung cancer. And the earlier a breast tumor is found, the more likely it is that the person survives their diagnosis.An international program called Discovering Hands trains blind women to detect even the smallest lumps and bumps through breast exams. The idea is to leverage the blind examiners’ sense of touch, which may be more acute than sighted people’s, to feel for breast abnormalities and, hopefully, catch cancer in an early stage.Discovering Hands has a cohort in India, a country where only around one in every two people diagnosed with breast cancer survive, and imaging equipment can be expensive or hard to come by.SciFri producer Ra
