I read a study that said HER2 cancers did not always do well with tamoxifen, but that this negative interaction was actually mitigated by herceptin--so the herceptin was a good thing. I asked my oncologist about this, since you continue tamoxifen for several years after you stop the herceptin, she said she had seen the studies, but that this problem has not been seen outside of the research setting. Basically, she said to stop worrying. I haven't, but I thought I'd stop worrying until I stopped the herceptin…I hope your concern is also unfounded; I haven't run across anything to contraindicate herceptin and tamoxifen…it seems pretty standard.
