IIT researchers turn to Artificial Intelligence for identifying cancer

A team of experts from IIT-Kharagpur (IIT-Kgp) and Tata Medical Centre (TMC), Kolkata, has devised a computer-assisted model they say can automatically grade breast cancer aggressiveness, even in remote settings, providing fresh impetus to Artificial Intelligence-based medical technology in India. It seeks to reduce human error in identifying breast cancer of various levels of aggressiveness to assist in distinguishing normal and low and higher risk malignant tumours. The team has tapped into deep learning, a form of AI concerned with algorithms inspired by the structure and function of the brain called artificial neural networks. The application revolves around a protein (or marker) called Ki-67 which is used to calculate an index that groups cancers in the "low" or "high" aggressiveness groups. The Ki-67 globally-approved index is used to help predict outcome or prognosis and help figure out what treatment might work best. It is increasingly being used by doctors to reflect cancer behaviour.
