Researchers at Cambridge University, led by Dr. Maria Garcia, are using advanced DNA technology to accelerate genetic analysis in breast cancer research. They aim to identify overactive genes in tumors, which could lead to more targeted treatments. The team has discovered four additional genes potentially involved in breast cancer development, bringing the goal of effective treatments closer.

How many more genes have been identified that are thought to play a role in breast cancer development?

What is the expected outcome of speeding up gene analysis according to the researchers?
