you got this girl! I was diagnosed in September, went to one oncologist, then decided to get a second opinion at Mayo Clinic. I went with Mayo, they did every possible test, etc. I had a lumpectomy, 5 rounds of radiation, and now on Letrozole (an estrogen blocker) I feel great!
You're in the most difficult part of the journey. Find an oncologist ( cancer center - a plus) you trust and in no time you'll be over the hump.
Good luck to you!!!
