# Genetic background and new mutations jointly direct cancer evolution

A new study in Nature reveals that an individual's genetic background sets the initial trajectory of cancer evolution, and this inherited context interacts with newly acquired mutations to shape tumor progression. The findings underscore the importance of considering inherited genetics alongside somatic mutations for understanding cancer development and personalizing treatment.

**Importance:** 3/5
