Welcome to MayoConnect, and sorry to hear about your diagnosis. However, I am always happy to hear about patients who get a molecular study and their doctor orders the correct therapy for their cancer!
Our experience was not good until the doctor did order the study and learned that my wife had a HER2 amplification with a Erbb2 mutation. Once he learned that he put my wife on a Targeted therapy that has worked wonders for the past 28 months.
Good luck!
