I need an idea of what to expect

The reply from CherylS is probably better than the explanation we received when we first learned about Jill's diagnosis. She is also right on about the Anthracycline chemo regimens (AC) and the latest research. Make sure your onc is up to date with the latest.

There are several options for ER+. You can take Tamoxifen. You can take meds to stop estrogen, or you could have surgery (oopherectomy sp?) to remove your ovaries, then take an AI. This decision is maybe not as easy since each option has risks/rewards. You are relatively young at 42 and may not want to completely stop estrogen production becasue of later issues such as osteoporosis and cardiac problems. At the same time, Tamoxifen increases other cancer risks. I am sure that others will weigh in on this.

Good Luck. Keep positive and learn as much about your treatment as possible. Do not be afraid to ask questions and research on your own.
