Why some cancers return: Robotic mini tumor tests point to new ways to target persister cells

AI Summary

New research utilizing robotic mini tumor models reveals mechanisms behind cancer recurrence, pinpointing persister cells that survive treatment and seed future tumors. This insight opens potential avenues for more targeted therapies against resilient cancer cells.

Cancer drugs can shrink fast-growing tumors. But sometimes a few tumor cells survive. These "persister" cells seed new tumors, forcing cancer patients into arduous cycles of testing and treatment.
