ER/PR Positive Breast Cancer & HER2/NEU

How common is ER/PR Positive Breast Cancer in one breast and HER2/NEU in the other breast?

[bluebutterfly2222]

I'm not sure I fully understand your question, as you did not provide the complete receptor stautus for each breast.

That is,: ER=/PR+ AND WHAT HER2 status in  "one breast?"

             HER2 (pos or neg?)  AND WHAT ER/PR status in "the other breast?"

Perhaps if you provide more information as well as your reason for the question, someone can provide an answer.

Best wishes...
