I was diagnosed over 5 years ago, Stage III, and I'm doing fine.
You may interested in this statistic I read just the other day in my doctor's office. Complications from diabetes kills more people than AIDS and breast cancer combined!
BC is extremely treatable and curable. Please take things one at a time. You don't need to be in a huge rush. One piece of advice I'll give you: be sure you REALLY like your doctors. I interviewed three Oncologists before deciding on one. I knew I'd be seeing one for many years to come. I actually look forward to going now, and 5 years ago, I sat in her office completely freaked out. Wish I knew then what I know now.
Take care, and my prayers will be with you. Please come back and let us know how you are doing.
