I am enclosing at least two links for each drug so you can read about them and decide which one you want to try first. There is no reason why you can't try one and if that one doesn't help you can try the other one.
Halaven is a new drug for metastatic breast cancer. Sheila has had experience with it, so hopefully she will respond to your request for information. I think she had some success with Halaven. If you find one of her posts she has some information in her bio about Halaven too.
Abraxane is believed to have less side effects than Taxol, because the binder/delivery system used is less of a problem than the one used in Taxol.
Have you seen my post in your thread about rashes and skin issues? I had a bad rash on my face. All my doctors thought it was cancer treatment related. However, I later found out it was from the binder or filler in the generic version of the blood pressure medicine I was taking at that time. If you are taking other medications perhaps the skin issues are from one of those.
We are behind you with our fingers crossed whichever treatment you decide to try first. All the best to you !! Let us know how you are doing.
