ER/PR - Tumors start out ER/PR +?/

[Olivia]

It seems I have heard recently (maybe here), that they believe that ER/PR - tumors began as ER/PR+?????? If that is the case, why am I not taking Tamoxifan to prevent a recurrence????

Also, Nancy Davidson, Oncologist at Hopkins, is doing a study about flipping you from ER/PR - to +. What would be the benefit? Just enabling you to take Tamoxifan?

Does anyone have any ideas about this?

Thanks,

Olivia
