Well, first of all hello to everyone, I'm from Chile so sorry about my english, but I have a lot of questions about this treatment because my mother suffers from Breast Cancer with methastasis on her Liver. The Chemotherapy didn't work on her body, so the doctors told her that she had to take the drug called Herceptin. Everything was doing fine, she had her 6 month's session with Herceptin, but her breast started to hurt her and it was hot, as if the nodule was inflamed or something, so the only treatment that the doctors decided for her at this moment is the mixture of this two drugs every 3 weeks. I wanted to know how effective this treatment is for a woman of 55 years old, because I don't see her defeated or something, I just see her with a lot of strength, but the secondary effects keep her in bed. That's my question, I hope that you can explain me more about its effectiveness on Breast Cancer. Thank you, and I'll keep in touch for further questions.
