Can dogs sniff cancer? AI joins the hunt in India

Bengaluru, India – When rescue dog Chloe is not tumbling across the grass on a farm outside India’s tech capital Bengaluru, she is learning to sniff human breath for cancer with a little help from artificial intelligence. Fitted with a 3D-printed helmet and harness packed with sensors, Chloe is part of experimental efforts to use dogs’ extraordinary sense of smell to develop a noninvasive test for the disease. A growing body of global research suggests dogs can be trained to detect cancer and other human illnesses, from Parkinson’s to COVID-19.
