Afternoon! Newly diagnosed -- waiting to see surgeon next week. Just got back the addendum to my pathology a few minutes ago and am ER/PR+, along with HER2-

I've just started to read up but want to know from others with the same results.

Many thanks!

I have the same diagnosis with those.  If you are ER/PR positive it means that your BC is dependent on estrogen to grow.  That usually means treatment with something like Tamoxifen for 5 years which is an estrogen blocker.  I will be starting Tamoxifen this week (I already did surgery and chemo).  If you are HER2 - it means you do not respond to a medicine called herceptin so that won't be a treatment for you.   HER2 + means the cancer is a bit more aggressive (from what I read - which is limited as I was HER2-).  Once you have surgery (lumpectomy or MX) the final pathology report  will help them with staging of your treatment.  Did they mention what grade you are?  (grade 1, 2 or 3).
