When exposed to cancer treatment like chemotherapy and radiation, brain and heart tissues in very young children are more prone to apoptosis or programmed cell death, researchers said.

Apoptosis, in which molecular signals order cells to self-destruct, plays an important role in deciding the “fate” of a developing cell.
