The gene expression pattern can both tell us something about which genes are involved in more invasive or aggressive breast cancer and can also tell us the prognosis of new patients. By identifying which genes are particularly active in breast cancer tumors, we can better understand the mechanisms driving the disease, potentially leading to the development of more targeted treatments. Additionally, by analyzing a patient's tumor for similar gene expression patterns, doctors can make more informed decisions about treatment options and prognosis.
