When my surgeon went over my Biopsy results, it was bad news. Aggressive 3IDC ER/PR+/+ and I would need surgery, lymph nodes removed, chemo, radiation and 5 or more years on Anastrozole. She told us she would send my Biopsy sample to Oncotype DX for a more intensive testing which would determine the best treatment plan. Results showed no chemo treatments and 4% chance of recurring in 10 years. Get the Oncotype test before surgery. Also, if you haven't had a chest CT scan recently, get one and possibly a heart echocardiogram. It will establish a baseline in case you unfortunately have lung damage. Good luck and God bless you on your journey to recovery.
