The Hidden Enemy: Why Cancer's Dormant Cells Pose a New Threat The latest research from the Medical Research Council (MRC) Laboratory of Medical Sciences has revealed a disturbing truth about breast cancer.
Scientists have found that hidden pockets of dormant cells, shielded by immune and connective tissue cells, can evade chemotherapy and reactivate later.
This phenomenon, known as quiescence, was previously observed in slower growing tumors. However, the new study shows that even aggressive forms of breast cancer harbor these silent killers.
