Inherited Genetics Play Larger Role in Cancer Evolution Than Previously Understood, Study Finds

A study co-led by Yale researchers and published in the journal Nature has provided direct evidence that inherited genetics significantly influence not only cancer risk but also how tumors acquire mutations, their growth rate, genetic instability, and overall evolution. These findings suggest that genetic background can steer cancerous tumors down different developmental paths, even when exposed to the same cancer-causing agents, potentially explaining variations in cancer behavior across individuals from diverse ancestral backgrounds.
