I just wanted to chime in that I'm on the AC-TH regimen and have had minimal side effects. I've finished AC and am halfway through Taxol. I'll continue with the Herceptin for the remainder of a year once the Taxol is completed. I am 34 years old and my heart continues to do fine. I'm not entirely sure why my oncologist (who I love) chose AC-TH, but I think because of my age he wanted to give me everything I could handle in the hopes of keeping this cancer gone forever. I'm slightly ER+ PR- and obviously Her2 positive. I had no node involvement and chose to have a double mastectomy. I've been able to continue teaching and though I've had days I feel "yucky", I've never had a day that made me regret the chemo. Good luck to you and your sister; mine has been amazing for me
