Indian-origin researchers at the University of Michigan have developed a new technique that is more effective than previous methods for growing tumor cells taken from cancer patients in the lab. This represents a major step forward in personalized cancer treatment. The tumor cells circulating in blood, known as circulating tumor cells, can provide valuable genetic information to help doctors make more informed treatment decisions tailored to individual patients. The new technique also helps address previous challenges with studying these rare cells found in early-stage cancer patients.
